SUMMARY

Average annual costs of establishing -a new small-scale greenhouse tomato operation (8000 square feet) in the Southeast va-ry from approximately $11000 to $20000 depending on struCtu_ral desigI1 and cropping schedule Highest entrepreneurial proJi__ts are realized with a polyetllylene-eovereci -house growing bot~ fallatid spring crops

Operations of a_rgund 8000 square feet are common in ~h-e Southeast in contra~t to muell larger operations -in the Indiana-Ohio area The industry is -well established in the Northeast but has orily rece~tly developed in the Southeast where growth has been quite rapid

Ri~~ng fuel costs and lack of marketing expe~~ence are the main gro~ers I p~()blems The wide difference Ln producer costs between Florida-grown field tomatoes and greenhouse ~omatoes limits the market for the greentJouse product Recent taste tests however show consumer preference for greenhouse tomatoes

Greenhouse tomato growers should e_s~ablish marketing channels before beginning production AmSlTIg the ma~keting possibilities are direct growerretailer sales roadside stands a~d route sa)_e-s To be successful the grower must understand the many facets of the business have managerial skills and patience and wor~ hard

ECONmncs OF GREENHOUSE TOMATO

PRODUCTION IN THE SOUTHEAST

Robert G McElroy James E Pallas Jr

INTRODUCTION

Annu~l per capita consumption of fresh tomatoes is exceeded f)ly by ~hat- of lettuce and potatoe among fresh vegetable productsil Consumption of fresh tomatoes remained fairly contant at around 12 pounds (54 kg) between 1965 and 1975 al~_h9ugh processed tomato ketchup an-d t_(Hnato sauce consumption increased This situation nowever reflects only connnercial production the popularity of home gardens -would increase the total In this paper discussion is limited to fresh tomatoes although processing-type tomatoes could also be grown in greenhouses

Interest in greenhouse tomato production in the SOutheast has been stimulated by several factors Aggressive- promotion by greenhouse manufacturers is one factor but claims made by advertisers as to the profitability of a greenhouse operation are frequent-ly e~aggerated For example a recent ad read -- $40000 per year net income with only five greenhouses less than one acre of land and nine hours per week per greenhouse (~) ~ A net income of approximately $40000 requires a beJ9re~tax income of $64000 Considering current cos ts and tabor requirements as presented later in this report this would anmi~1-1y require nearly 14 acres and over middot15000 labor hours (for just 8 months production)

Another factor is the iilterest in alternative enterprises for rural development The Agricultural

Research Service (ARS) u S Department of Agric~Jture (USDA)- at Ci-emso~ SC is conducting research in the area of greenh6use-residence combinations Thcent Rural Development Center at Reidsville Ga is working with rural families in growing greenhouse tQmatqes forthe Savannah market

The industry appeals to retirees and others -looking for a part-time source of income Since greenhouse_ tomatoes are typically grown during the wi_nter when 0 tIter crops require minimal attention many small farmers see this as an opportunity to mor~ ~ully utilize their time in an off season

The greenhouse tomato has been gro_wTI in the -North Central United States since the beginning of this century (2) Before the developmerit 01 modern efficient t~ansportation it provided the only supp~y of fresh tomatoes in the area du_ring the late fall and winte_r Competition is nO- more keen from field-grown to~toes from Florida and Mexico but the longtime accepcance of the product continues

In the Southeast the industry is relatively new but growing Between 1969 and 1974 tile area under pr_oduction of gre~nhouse tomatoes in the Southeast (North Csectlrolina Kentucky Georgia Alabama ~ssissipp~ Tennessee Virginia and South Carolina) increa~ed approximately 700 percent (9 12) lJorth Carolina is the leading fiouthern State with an-estimated 14 million square feet (130000 square meters) devoted to the crop lt~) Growers in North Cardlina use amiddot low cost structure and fuel oil heating

Rising fuel costs present a major problem to t_he grmvers The lack of marketing experie_rice by growers is another problem Due to the_e and other factors many people who try 10 c-ofnmercially produce greenhouse vegetables are not successful In an attempt to better deal with the~e

problem growers are asking their State experiment statiilns and ARSUSDA Eor help

Ongoing research at several southea-stern centers is concentrating on these probleTItS Scientists at the ARS Southern Piedmont Conservat-ion Research Center Watkinsville Ga are deveipplng cultural pract-ices to recommend for this area The University of Georgia is working on a similar project In Alabama the Tennessee Valley Authority is experimenting with heating greenhouses using heated waste water frq~ power generating plants Solar energy co(ve_rsion for ~supplemental heat is being tested in Florida South Ca~olina and other States

This report presents the resu~ts of economic research un~erta~en in cooperation with the Agricultural Research Service the primary objectiveof the report is to develop basic economic guidelines for plant science research on greenhouse vegetables and to provide benchmark data for

those involved in the industry Specifically this includes

1 Determining the pattern of seasonal variation in market prices for selected southeastern markets as a basis for determining most favorable marketing seasons

2 Evaluating seasonal changes in the or1g1ns and volume of market supplies for selected southeastern markets and

3 Est ima ting break-even pr_ices under al terna tivel managentent systems and for different type structures and evaluating their sensitivity to wage rates and average yields

t1arket Patterns

Greenhouse toma toes grown during the fall middotJinter and spring m~nths must compete for a share of the market with the mature green and vine-ripe field-grown tomatoes from Florfda Hexico and California During the summer months locally grown field tomatoes mal~e up the largest share of local markets The sources of supply of fresh tomatoes in the two major southeastern markets are shown in figure 1

Average wholesale prices for field-grown tomatoes for these markets are snown in figuremiddot 2 1ITO periods of high prices are evident a winter high from November through January and a spring high from April through July Data are not kept ori monthly prices for greenhouse tomatoes in the Southeast but f~om figure 2 it can be seen that the greenhouse grower should harvest during these high-price months to better compete in the market

Taste Panel Tests

Field-grQoffi tomatoes for shipping to distant markets are generally of two classes depending on their stage of maturity at harvest These are mature green and vine-ripe which are predominant in Florida and Mexico respectively Mature green tomatoes are harvested in the green stage and

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

The commercial field-groWl- samples were obtained from the State Farmers1 Market -in Atlanta These had been grown in Florida ~and Mexico and shipped greet) to the market I The samples remained at room temperature to ripen for evalua tion Greenhouse samples were harvested as breakeirs

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

the three- structures~ The profits are the retur_l_s exp_ected at each price For examplcent f~r one crop annually in the pl~st-ic house at a wage rate of $250 per hour and an averlge annual yield of 13 pounds per plant negative profits are shown at prices of $45 per pound and less while $50 per pound are required for positive profits (to the nearest $05) For two crops per year the yield per plant is the total weight for both crops (yield per space occupied by one plant) Tomato prices in the two-crop schedule1are average prices for both crops (each crops price weighted by that crops percentage of its average yield to total annual yield)

It may be 61 interest t9 d~tehnine a~ just whatmiddot price (or w~ge ate or yield) the operation will break even in figure 3 (data from table 4) the curves shm the minimum price required for various yields so as not to lose money (break-even points)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

where y = yield per plant (13 lbs)

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

SUMMARY

Average annual costs of establishing -a new small-scale greenhouse tomato operation (8000 square feet) in the Southeast va-ry from approximately $11000 to $20000 depending on struCtu_ral desigI1 and cropping schedule Highest entrepreneurial proJi__ts are realized with a polyetllylene-eovereci -house growing bot~ fallatid spring crops

Operations of a_rgund 8000 square feet are common in ~h-e Southeast in contra~t to muell larger operations -in the Indiana-Ohio area The industry is -well established in the Northeast but has orily rece~tly developed in the Southeast where growth has been quite rapid

Ri~~ng fuel costs and lack of marketing expe~~ence are the main gro~ers I p~()blems The wide difference Ln producer costs between Florida-grown field tomatoes and greenhouse ~omatoes limits the market for the greentJouse product Recent taste tests however show consumer preference for greenhouse tomatoes

Greenhouse tomato growers should e_s~ablish marketing channels before beginning production AmSlTIg the ma~keting possibilities are direct growerretailer sales roadside stands a~d route sa)_e-s To be successful the grower must understand the many facets of the business have managerial skills and patience and wor~ hard

ECONmncs OF GREENHOUSE TOMATO

PRODUCTION IN THE SOUTHEAST

Robert G McElroy James E Pallas Jr

Warren K Trotter

INTRODUCTION

Annu~l per capita consumption of fresh tomatoes is exceeded f)ly by ~hat- of lettuce and potatoe among fresh vegetable productsil Consumption of fresh tomatoes remained fairly contant at around 12 pounds (54 kg) between 1965 and 1975 al~_h9ugh processed tomato ketchup an-d t_(Hnato sauce consumption increased This situation nowever reflects only connnercial production the popularity of home gardens -would increase the total In this paper discussion is limited to fresh tomatoes although processing-type tomatoes could also be grown in greenhouses

Interest in greenhouse tomato production in the SOutheast has been stimulated by several factors Aggressive- promotion by greenhouse manufacturers is one factor but claims made by advertisers as to the profitability of a greenhouse operation are frequent-ly e~aggerated For example a recent ad read -- $40000 per year net income with only five greenhouses less than one acre of land and nine hours per week per greenhouse (~) ~ A net income of approximately $40000 requires a beJ9re~tax income of $64000 Considering current cos ts and tabor requirements as presented later in this report this would anmi~1-1y require nearly 14 acres and over middot15000 labor hours (for just 8 months production)

Another factor is the iilterest in alternative enterprises for rural development The Agricultural

Research Service (ARS) u S Department of Agric~Jture (USDA)- at Ci-emso~ SC is conducting research in the area of greenh6use-residence combinations Thcent Rural Development Center at Reidsville Ga is working with rural families in growing greenhouse tQmatqes forthe Savannah market

The industry appeals to retirees and others -looking for a part-time source of income Since greenhouse_ tomatoes are typically grown during the wi_nter when 0 tIter crops require minimal attention many small farmers see this as an opportunity to mor~ ~ully utilize their time in an off season

The greenhouse tomato has been gro_wTI in the -North Central United States since the beginning of this century (2) Before the developmerit 01 modern efficient t~ansportation it provided the only supp~y of fresh tomatoes in the area du_ring the late fall and winte_r Competition is nO- more keen from field-grown to~toes from Florida and Mexico but the longtime accepcance of the product continues

In the Southeast the industry is relatively new but growing Between 1969 and 1974 tile area under pr_oduction of gre~nhouse tomatoes in the Southeast (North Csectlrolina Kentucky Georgia Alabama ~ssissipp~ Tennessee Virginia and South Carolina) increa~ed approximately 700 percent (9 12) lJorth Carolina is the leading fiouthern State with an-estimated 14 million square feet (130000 square meters) devoted to the crop lt~) Growers in North Cardlina use amiddot low cost structure and fuel oil heating

Rising fuel costs present a major problem to t_he grmvers The lack of marketing experie_rice by growers is another problem Due to the_e and other factors many people who try 10 c-ofnmercially produce greenhouse vegetables are not successful In an attempt to better deal with the~e

problem growers are asking their State experiment statiilns and ARSUSDA Eor help

Ongoing research at several southea-stern centers is concentrating on these probleTItS Scientists at the ARS Southern Piedmont Conservat-ion Research Center Watkinsville Ga are deveipplng cultural pract-ices to recommend for this area The University of Georgia is working on a similar project In Alabama the Tennessee Valley Authority is experimenting with heating greenhouses using heated waste water frq~ power generating plants Solar energy co(ve_rsion for ~supplemental heat is being tested in Florida South Ca~olina and other States

This report presents the resu~ts of economic research un~erta~en in cooperation with the Agricultural Research Service the primary objectiveof the report is to develop basic economic guidelines for plant science research on greenhouse vegetables and to provide benchmark data for

those involved in the industry Specifically this includes

1 Determining the pattern of seasonal variation in market prices for selected southeastern markets as a basis for determining most favorable marketing seasons

2 Evaluating seasonal changes in the or1g1ns and volume of market supplies for selected southeastern markets and

3 Est ima ting break-even pr_ices under al terna tivel managentent systems and for different type structures and evaluating their sensitivity to wage rates and average yields

t1arket Patterns

Greenhouse toma toes grown during the fall middotJinter and spring m~nths must compete for a share of the market with the mature green and vine-ripe field-grown tomatoes from Florfda Hexico and California During the summer months locally grown field tomatoes mal~e up the largest share of local markets The sources of supply of fresh tomatoes in the two major southeastern markets are shown in figure 1

Average wholesale prices for field-grown tomatoes for these markets are snown in figuremiddot 2 1ITO periods of high prices are evident a winter high from November through January and a spring high from April through July Data are not kept ori monthly prices for greenhouse tomatoes in the Southeast but f~om figure 2 it can be seen that the greenhouse grower should harvest during these high-price months to better compete in the market

Taste Panel Tests

Field-grQoffi tomatoes for shipping to distant markets are generally of two classes depending on their stage of maturity at harvest These are mature green and vine-ripe which are predominant in Florida and Mexico respectively Mature green tomatoes are harvested in the green stage and

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

APPENDIX

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

SUMMARY

Average annual costs of establishing -a new small-scale greenhouse tomato operation (8000 square feet) in the Southeast va-ry from approximately $11000 to $20000 depending on struCtu_ral desigI1 and cropping schedule Highest entrepreneurial proJi__ts are realized with a polyetllylene-eovereci -house growing bot~ fallatid spring crops

Operations of a_rgund 8000 square feet are common in ~h-e Southeast in contra~t to muell larger operations -in the Indiana-Ohio area The industry is -well established in the Northeast but has orily rece~tly developed in the Southeast where growth has been quite rapid

Ri~~ng fuel costs and lack of marketing expe~~ence are the main gro~ers I p~()blems The wide difference Ln producer costs between Florida-grown field tomatoes and greenhouse ~omatoes limits the market for the greentJouse product Recent taste tests however show consumer preference for greenhouse tomatoes

Greenhouse tomato growers should e_s~ablish marketing channels before beginning production AmSlTIg the ma~keting possibilities are direct growerretailer sales roadside stands a~d route sa)_e-s To be successful the grower must understand the many facets of the business have managerial skills and patience and wor~ hard

ECONmncs OF GREENHOUSE TOMATO

PRODUCTION IN THE SOUTHEAST

Robert G McElroy James E Pallas Jr

Warren K Trotter

INTRODUCTION

Annu~l per capita consumption of fresh tomatoes is exceeded f)ly by ~hat- of lettuce and potatoe among fresh vegetable productsil Consumption of fresh tomatoes remained fairly contant at around 12 pounds (54 kg) between 1965 and 1975 al~_h9ugh processed tomato ketchup an-d t_(Hnato sauce consumption increased This situation nowever reflects only connnercial production the popularity of home gardens -would increase the total In this paper discussion is limited to fresh tomatoes although processing-type tomatoes could also be grown in greenhouses

Interest in greenhouse tomato production in the SOutheast has been stimulated by several factors Aggressive- promotion by greenhouse manufacturers is one factor but claims made by advertisers as to the profitability of a greenhouse operation are frequent-ly e~aggerated For example a recent ad read -- $40000 per year net income with only five greenhouses less than one acre of land and nine hours per week per greenhouse (~) ~ A net income of approximately $40000 requires a beJ9re~tax income of $64000 Considering current cos ts and tabor requirements as presented later in this report this would anmi~1-1y require nearly 14 acres and over middot15000 labor hours (for just 8 months production)

Another factor is the iilterest in alternative enterprises for rural development The Agricultural

Research Service (ARS) u S Department of Agric~Jture (USDA)- at Ci-emso~ SC is conducting research in the area of greenh6use-residence combinations Thcent Rural Development Center at Reidsville Ga is working with rural families in growing greenhouse tQmatqes forthe Savannah market

The industry appeals to retirees and others -looking for a part-time source of income Since greenhouse_ tomatoes are typically grown during the wi_nter when 0 tIter crops require minimal attention many small farmers see this as an opportunity to mor~ ~ully utilize their time in an off season

The greenhouse tomato has been gro_wTI in the -North Central United States since the beginning of this century (2) Before the developmerit 01 modern efficient t~ansportation it provided the only supp~y of fresh tomatoes in the area du_ring the late fall and winte_r Competition is nO- more keen from field-grown to~toes from Florida and Mexico but the longtime accepcance of the product continues

In the Southeast the industry is relatively new but growing Between 1969 and 1974 tile area under pr_oduction of gre~nhouse tomatoes in the Southeast (North Csectlrolina Kentucky Georgia Alabama ~ssissipp~ Tennessee Virginia and South Carolina) increa~ed approximately 700 percent (9 12) lJorth Carolina is the leading fiouthern State with an-estimated 14 million square feet (130000 square meters) devoted to the crop lt~) Growers in North Cardlina use amiddot low cost structure and fuel oil heating

Rising fuel costs present a major problem to t_he grmvers The lack of marketing experie_rice by growers is another problem Due to the_e and other factors many people who try 10 c-ofnmercially produce greenhouse vegetables are not successful In an attempt to better deal with the~e

problem growers are asking their State experiment statiilns and ARSUSDA Eor help

Ongoing research at several southea-stern centers is concentrating on these probleTItS Scientists at the ARS Southern Piedmont Conservat-ion Research Center Watkinsville Ga are deveipplng cultural pract-ices to recommend for this area The University of Georgia is working on a similar project In Alabama the Tennessee Valley Authority is experimenting with heating greenhouses using heated waste water frq~ power generating plants Solar energy co(ve_rsion for ~supplemental heat is being tested in Florida South Ca~olina and other States

This report presents the resu~ts of economic research un~erta~en in cooperation with the Agricultural Research Service the primary objectiveof the report is to develop basic economic guidelines for plant science research on greenhouse vegetables and to provide benchmark data for

those involved in the industry Specifically this includes

1 Determining the pattern of seasonal variation in market prices for selected southeastern markets as a basis for determining most favorable marketing seasons

2 Evaluating seasonal changes in the or1g1ns and volume of market supplies for selected southeastern markets and

3 Est ima ting break-even pr_ices under al terna tivel managentent systems and for different type structures and evaluating their sensitivity to wage rates and average yields

t1arket Patterns

Greenhouse toma toes grown during the fall middotJinter and spring m~nths must compete for a share of the market with the mature green and vine-ripe field-grown tomatoes from Florfda Hexico and California During the summer months locally grown field tomatoes mal~e up the largest share of local markets The sources of supply of fresh tomatoes in the two major southeastern markets are shown in figure 1

Average wholesale prices for field-grown tomatoes for these markets are snown in figuremiddot 2 1ITO periods of high prices are evident a winter high from November through January and a spring high from April through July Data are not kept ori monthly prices for greenhouse tomatoes in the Southeast but f~om figure 2 it can be seen that the greenhouse grower should harvest during these high-price months to better compete in the market

Taste Panel Tests

Field-grQoffi tomatoes for shipping to distant markets are generally of two classes depending on their stage of maturity at harvest These are mature green and vine-ripe which are predominant in Florida and Mexico respectively Mature green tomatoes are harvested in the green stage and

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

~

11

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

SUMMARY

Average annual costs of establishing -a new small-scale greenhouse tomato operation (8000 square feet) in the Southeast va-ry from approximately $11000 to $20000 depending on struCtu_ral desigI1 and cropping schedule Highest entrepreneurial proJi__ts are realized with a polyetllylene-eovereci -house growing bot~ fallatid spring crops

Operations of a_rgund 8000 square feet are common in ~h-e Southeast in contra~t to muell larger operations -in the Indiana-Ohio area The industry is -well established in the Northeast but has orily rece~tly developed in the Southeast where growth has been quite rapid

Ri~~ng fuel costs and lack of marketing expe~~ence are the main gro~ers I p~()blems The wide difference Ln producer costs between Florida-grown field tomatoes and greenhouse ~omatoes limits the market for the greentJouse product Recent taste tests however show consumer preference for greenhouse tomatoes

Greenhouse tomato growers should e_s~ablish marketing channels before beginning production AmSlTIg the ma~keting possibilities are direct growerretailer sales roadside stands a~d route sa)_e-s To be successful the grower must understand the many facets of the business have managerial skills and patience and wor~ hard

ECONmncs OF GREENHOUSE TOMATO

PRODUCTION IN THE SOUTHEAST

Robert G McElroy James E Pallas Jr

Warren K Trotter

INTRODUCTION

Annu~l per capita consumption of fresh tomatoes is exceeded f)ly by ~hat- of lettuce and potatoe among fresh vegetable productsil Consumption of fresh tomatoes remained fairly contant at around 12 pounds (54 kg) between 1965 and 1975 al~_h9ugh processed tomato ketchup an-d t_(Hnato sauce consumption increased This situation nowever reflects only connnercial production the popularity of home gardens -would increase the total In this paper discussion is limited to fresh tomatoes although processing-type tomatoes could also be grown in greenhouses

Interest in greenhouse tomato production in the SOutheast has been stimulated by several factors Aggressive- promotion by greenhouse manufacturers is one factor but claims made by advertisers as to the profitability of a greenhouse operation are frequent-ly e~aggerated For example a recent ad read -- $40000 per year net income with only five greenhouses less than one acre of land and nine hours per week per greenhouse (~) ~ A net income of approximately $40000 requires a beJ9re~tax income of $64000 Considering current cos ts and tabor requirements as presented later in this report this would anmi~1-1y require nearly 14 acres and over middot15000 labor hours (for just 8 months production)

Another factor is the iilterest in alternative enterprises for rural development The Agricultural

The industry appeals to retirees and others -looking for a part-time source of income Since greenhouse_ tomatoes are typically grown during the wi_nter when 0 tIter crops require minimal attention many small farmers see this as an opportunity to mor~ ~ully utilize their time in an off season

The greenhouse tomato has been gro_wTI in the -North Central United States since the beginning of this century (2) Before the developmerit 01 modern efficient t~ansportation it provided the only supp~y of fresh tomatoes in the area du_ring the late fall and winte_r Competition is nO- more keen from field-grown to~toes from Florida and Mexico but the longtime accepcance of the product continues

In the Southeast the industry is relatively new but growing Between 1969 and 1974 tile area under pr_oduction of gre~nhouse tomatoes in the Southeast (North Csectlrolina Kentucky Georgia Alabama ~ssissipp~ Tennessee Virginia and South Carolina) increa~ed approximately 700 percent (9 12) lJorth Carolina is the leading fiouthern State with an-estimated 14 million square feet (130000 square meters) devoted to the crop lt~) Growers in North Cardlina use amiddot low cost structure and fuel oil heating

Rising fuel costs present a major problem to t_he grmvers The lack of marketing experie_rice by growers is another problem Due to the_e and other factors many people who try 10 c-ofnmercially produce greenhouse vegetables are not successful In an attempt to better deal with the~e

problem growers are asking their State experiment statiilns and ARSUSDA Eor help

Ongoing research at several southea-stern centers is concentrating on these probleTItS Scientists at the ARS Southern Piedmont Conservat-ion Research Center Watkinsville Ga are deveipplng cultural pract-ices to recommend for this area The University of Georgia is working on a similar project In Alabama the Tennessee Valley Authority is experimenting with heating greenhouses using heated waste water frq~ power generating plants Solar energy co(ve_rsion for ~supplemental heat is being tested in Florida South Ca~olina and other States

This report presents the resu~ts of economic research un~erta~en in cooperation with the Agricultural Research Service the primary objectiveof the report is to develop basic economic guidelines for plant science research on greenhouse vegetables and to provide benchmark data for

those involved in the industry Specifically this includes

1 Determining the pattern of seasonal variation in market prices for selected southeastern markets as a basis for determining most favorable marketing seasons

2 Evaluating seasonal changes in the or1g1ns and volume of market supplies for selected southeastern markets and

3 Est ima ting break-even pr_ices under al terna tivel managentent systems and for different type structures and evaluating their sensitivity to wage rates and average yields

t1arket Patterns

Greenhouse toma toes grown during the fall middotJinter and spring m~nths must compete for a share of the market with the mature green and vine-ripe field-grown tomatoes from Florfda Hexico and California During the summer months locally grown field tomatoes mal~e up the largest share of local markets The sources of supply of fresh tomatoes in the two major southeastern markets are shown in figure 1

Average wholesale prices for field-grown tomatoes for these markets are snown in figuremiddot 2 1ITO periods of high prices are evident a winter high from November through January and a spring high from April through July Data are not kept ori monthly prices for greenhouse tomatoes in the Southeast but f~om figure 2 it can be seen that the greenhouse grower should harvest during these high-price months to better compete in the market

Taste Panel Tests

Field-grQoffi tomatoes for shipping to distant markets are generally of two classes depending on their stage of maturity at harvest These are mature green and vine-ripe which are predominant in Florida and Mexico respectively Mature green tomatoes are harvested in the green stage and

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

the three- structures~ The profits are the retur_l_s exp_ected at each price For examplcent f~r one crop annually in the pl~st-ic house at a wage rate of $250 per hour and an averlge annual yield of 13 pounds per plant negative profits are shown at prices of $45 per pound and less while $50 per pound are required for positive profits (to the nearest $05) For two crops per year the yield per plant is the total weight for both crops (yield per space occupied by one plant) Tomato prices in the two-crop schedule1are average prices for both crops (each crops price weighted by that crops percentage of its average yield to total annual yield)

It may be 61 interest t9 d~tehnine a~ just whatmiddot price (or w~ge ate or yield) the operation will break even in figure 3 (data from table 4) the curves shm the minimum price required for various yields so as not to lose money (break-even points)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

~

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

ECONmncs OF GREENHOUSE TOMATO

PRODUCTION IN THE SOUTHEAST

Robert G McElroy James E Pallas Jr

INTRODUCTION

Annu~l per capita consumption of fresh tomatoes is exceeded f)ly by ~hat- of lettuce and potatoe among fresh vegetable productsil Consumption of fresh tomatoes remained fairly contant at around 12 pounds (54 kg) between 1965 and 1975 al~_h9ugh processed tomato ketchup an-d t_(Hnato sauce consumption increased This situation nowever reflects only connnercial production the popularity of home gardens -would increase the total In this paper discussion is limited to fresh tomatoes although processing-type tomatoes could also be grown in greenhouses

Interest in greenhouse tomato production in the SOutheast has been stimulated by several factors Aggressive- promotion by greenhouse manufacturers is one factor but claims made by advertisers as to the profitability of a greenhouse operation are frequent-ly e~aggerated For example a recent ad read -- $40000 per year net income with only five greenhouses less than one acre of land and nine hours per week per greenhouse (~) ~ A net income of approximately $40000 requires a beJ9re~tax income of $64000 Considering current cos ts and tabor requirements as presented later in this report this would anmi~1-1y require nearly 14 acres and over middot15000 labor hours (for just 8 months production)

Another factor is the iilterest in alternative enterprises for rural development The Agricultural

Research Service (ARS) u S Department of Agric~Jture (USDA)- at Ci-emso~ SC is conducting research in the area of greenh6use-residence combinations Thcent Rural Development Center at Reidsville Ga is working with rural families in growing greenhouse tQmatqes forthe Savannah market

The industry appeals to retirees and others -looking for a part-time source of income Since greenhouse_ tomatoes are typically grown during the wi_nter when 0 tIter crops require minimal attention many small farmers see this as an opportunity to mor~ ~ully utilize their time in an off season

The greenhouse tomato has been gro_wTI in the -North Central United States since the beginning of this century (2) Before the developmerit 01 modern efficient t~ansportation it provided the only supp~y of fresh tomatoes in the area du_ring the late fall and winte_r Competition is nO- more keen from field-grown to~toes from Florida and Mexico but the longtime accepcance of the product continues

In the Southeast the industry is relatively new but growing Between 1969 and 1974 tile area under pr_oduction of gre~nhouse tomatoes in the Southeast (North Csectlrolina Kentucky Georgia Alabama ~ssissipp~ Tennessee Virginia and South Carolina) increa~ed approximately 700 percent (9 12) lJorth Carolina is the leading fiouthern State with an-estimated 14 million square feet (130000 square meters) devoted to the crop lt~) Growers in North Cardlina use amiddot low cost structure and fuel oil heating

Rising fuel costs present a major problem to t_he grmvers The lack of marketing experie_rice by growers is another problem Due to the_e and other factors many people who try 10 c-ofnmercially produce greenhouse vegetables are not successful In an attempt to better deal with the~e

problem growers are asking their State experiment statiilns and ARSUSDA Eor help

Ongoing research at several southea-stern centers is concentrating on these probleTItS Scientists at the ARS Southern Piedmont Conservat-ion Research Center Watkinsville Ga are deveipplng cultural pract-ices to recommend for this area The University of Georgia is working on a similar project In Alabama the Tennessee Valley Authority is experimenting with heating greenhouses using heated waste water frq~ power generating plants Solar energy co(ve_rsion for ~supplemental heat is being tested in Florida South Ca~olina and other States

This report presents the resu~ts of economic research un~erta~en in cooperation with the Agricultural Research Service the primary objectiveof the report is to develop basic economic guidelines for plant science research on greenhouse vegetables and to provide benchmark data for

those involved in the industry Specifically this includes

1 Determining the pattern of seasonal variation in market prices for selected southeastern markets as a basis for determining most favorable marketing seasons

2 Evaluating seasonal changes in the or1g1ns and volume of market supplies for selected southeastern markets and

3 Est ima ting break-even pr_ices under al terna tivel managentent systems and for different type structures and evaluating their sensitivity to wage rates and average yields

t1arket Patterns

Greenhouse toma toes grown during the fall middotJinter and spring m~nths must compete for a share of the market with the mature green and vine-ripe field-grown tomatoes from Florfda Hexico and California During the summer months locally grown field tomatoes mal~e up the largest share of local markets The sources of supply of fresh tomatoes in the two major southeastern markets are shown in figure 1

Average wholesale prices for field-grown tomatoes for these markets are snown in figuremiddot 2 1ITO periods of high prices are evident a winter high from November through January and a spring high from April through July Data are not kept ori monthly prices for greenhouse tomatoes in the Southeast but f~om figure 2 it can be seen that the greenhouse grower should harvest during these high-price months to better compete in the market

Taste Panel Tests

Field-grQoffi tomatoes for shipping to distant markets are generally of two classes depending on their stage of maturity at harvest These are mature green and vine-ripe which are predominant in Florida and Mexico respectively Mature green tomatoes are harvested in the green stage and

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

the three- structures~ The profits are the retur_l_s exp_ected at each price For examplcent f~r one crop annually in the pl~st-ic house at a wage rate of $250 per hour and an averlge annual yield of 13 pounds per plant negative profits are shown at prices of $45 per pound and less while $50 per pound are required for positive profits (to the nearest $05) For two crops per year the yield per plant is the total weight for both crops (yield per space occupied by one plant) Tomato prices in the two-crop schedule1are average prices for both crops (each crops price weighted by that crops percentage of its average yield to total annual yield)

It may be 61 interest t9 d~tehnine a~ just whatmiddot price (or w~ge ate or yield) the operation will break even in figure 3 (data from table 4) the curves shm the minimum price required for various yields so as not to lose money (break-even points)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

~

11

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

Research Service (ARS) u S Department of Agric~Jture (USDA)- at Ci-emso~ SC is conducting research in the area of greenh6use-residence combinations Thcent Rural Development Center at Reidsville Ga is working with rural families in growing greenhouse tQmatqes forthe Savannah market

The industry appeals to retirees and others -looking for a part-time source of income Since greenhouse_ tomatoes are typically grown during the wi_nter when 0 tIter crops require minimal attention many small farmers see this as an opportunity to mor~ ~ully utilize their time in an off season

The greenhouse tomato has been gro_wTI in the -North Central United States since the beginning of this century (2) Before the developmerit 01 modern efficient t~ansportation it provided the only supp~y of fresh tomatoes in the area du_ring the late fall and winte_r Competition is nO- more keen from field-grown to~toes from Florida and Mexico but the longtime accepcance of the product continues

In the Southeast the industry is relatively new but growing Between 1969 and 1974 tile area under pr_oduction of gre~nhouse tomatoes in the Southeast (North Csectlrolina Kentucky Georgia Alabama ~ssissipp~ Tennessee Virginia and South Carolina) increa~ed approximately 700 percent (9 12) lJorth Carolina is the leading fiouthern State with an-estimated 14 million square feet (130000 square meters) devoted to the crop lt~) Growers in North Cardlina use amiddot low cost structure and fuel oil heating

Rising fuel costs present a major problem to t_he grmvers The lack of marketing experie_rice by growers is another problem Due to the_e and other factors many people who try 10 c-ofnmercially produce greenhouse vegetables are not successful In an attempt to better deal with the~e

problem growers are asking their State experiment statiilns and ARSUSDA Eor help

Ongoing research at several southea-stern centers is concentrating on these probleTItS Scientists at the ARS Southern Piedmont Conservat-ion Research Center Watkinsville Ga are deveipplng cultural pract-ices to recommend for this area The University of Georgia is working on a similar project In Alabama the Tennessee Valley Authority is experimenting with heating greenhouses using heated waste water frq~ power generating plants Solar energy co(ve_rsion for ~supplemental heat is being tested in Florida South Ca~olina and other States

This report presents the resu~ts of economic research un~erta~en in cooperation with the Agricultural Research Service the primary objectiveof the report is to develop basic economic guidelines for plant science research on greenhouse vegetables and to provide benchmark data for

those involved in the industry Specifically this includes

1 Determining the pattern of seasonal variation in market prices for selected southeastern markets as a basis for determining most favorable marketing seasons

2 Evaluating seasonal changes in the or1g1ns and volume of market supplies for selected southeastern markets and

3 Est ima ting break-even pr_ices under al terna tivel managentent systems and for different type structures and evaluating their sensitivity to wage rates and average yields

t1arket Patterns

Greenhouse toma toes grown during the fall middotJinter and spring m~nths must compete for a share of the market with the mature green and vine-ripe field-grown tomatoes from Florfda Hexico and California During the summer months locally grown field tomatoes mal~e up the largest share of local markets The sources of supply of fresh tomatoes in the two major southeastern markets are shown in figure 1

Average wholesale prices for field-grown tomatoes for these markets are snown in figuremiddot 2 1ITO periods of high prices are evident a winter high from November through January and a spring high from April through July Data are not kept ori monthly prices for greenhouse tomatoes in the Southeast but f~om figure 2 it can be seen that the greenhouse grower should harvest during these high-price months to better compete in the market

Taste Panel Tests

Field-grQoffi tomatoes for shipping to distant markets are generally of two classes depending on their stage of maturity at harvest These are mature green and vine-ripe which are predominant in Florida and Mexico respectively Mature green tomatoes are harvested in the green stage and

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

the three- structures~ The profits are the retur_l_s exp_ected at each price For examplcent f~r one crop annually in the pl~st-ic house at a wage rate of $250 per hour and an averlge annual yield of 13 pounds per plant negative profits are shown at prices of $45 per pound and less while $50 per pound are required for positive profits (to the nearest $05) For two crops per year the yield per plant is the total weight for both crops (yield per space occupied by one plant) Tomato prices in the two-crop schedule1are average prices for both crops (each crops price weighted by that crops percentage of its average yield to total annual yield)

It may be 61 interest t9 d~tehnine a~ just whatmiddot price (or w~ge ate or yield) the operation will break even in figure 3 (data from table 4) the curves shm the minimum price required for various yields so as not to lose money (break-even points)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

~

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

where y = yield per plant (13 lbs)

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

This report presents the resu~ts of economic research un~erta~en in cooperation with the Agricultural Research Service the primary objectiveof the report is to develop basic economic guidelines for plant science research on greenhouse vegetables and to provide benchmark data for

those involved in the industry Specifically this includes

1 Determining the pattern of seasonal variation in market prices for selected southeastern markets as a basis for determining most favorable marketing seasons

2 Evaluating seasonal changes in the or1g1ns and volume of market supplies for selected southeastern markets and

3 Est ima ting break-even pr_ices under al terna tivel managentent systems and for different type structures and evaluating their sensitivity to wage rates and average yields

t1arket Patterns

Greenhouse toma toes grown during the fall middotJinter and spring m~nths must compete for a share of the market with the mature green and vine-ripe field-grown tomatoes from Florfda Hexico and California During the summer months locally grown field tomatoes mal~e up the largest share of local markets The sources of supply of fresh tomatoes in the two major southeastern markets are shown in figure 1

Average wholesale prices for field-grown tomatoes for these markets are snown in figuremiddot 2 1ITO periods of high prices are evident a winter high from November through January and a spring high from April through July Data are not kept ori monthly prices for greenhouse tomatoes in the Southeast but f~om figure 2 it can be seen that the greenhouse grower should harvest during these high-price months to better compete in the market

Taste Panel Tests

Field-grQoffi tomatoes for shipping to distant markets are generally of two classes depending on their stage of maturity at harvest These are mature green and vine-ripe which are predominant in Florida and Mexico respectively Mature green tomatoes are harvested in the green stage and

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

where y = yield per plant (13 lbs)

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

Ttvo tests were conducted by the USDA at the Richard B Russell Agricul tural Research Center Athens Ga to I determine if there was a discernible taste difference between field-grown and greenhouse tomatoes One test ranked 18 varieties of greenhouse tomatoes by characteristics (acidity sweetness firmness of flesh and toughness of skin) and the second ranked five samples (one field-grown and four greenhouse var-ieti~s) by taste preference

In testing the greenhouse and field-grown tomatoes sample selection and preparation were as fol_lows

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

are and

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

where y = yield per plant (13 lbs)

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

MANAGEMENT SYSTEMS AND BREAK-EVEN ANALYSIS

Gre-enhouse tomato produc tion in the Southeast is typically a small enterprise An average greenhouse operation includes four houses of approximatley 2000 square feet (185 square meters) each with newer houses usually covered with polyethylene or fiberglass (sect) These houses are principally one of two general designs quonset shaped ui-ing -gaJvanized steel pipe as framing and ridge and furrow shaped using either wood framing for plastic houses or aluminum for glass houses The quonset house is the less expensive and easier to set up

Approximately 500 plants would be found in a typical house of -2000 square feet In most areas of the Southeast peat moss or pine bark mixed with vermiculite is frequently used as a growing medium Researcl has SltOWTI that two beds of 5 to 6 feet each in width with four rows of plants produce maximum yield (8) and maximize bed space with respect to wal1-ways Ohio studies (2) recommend 8-11000 plants per acre (20-27000 plants pe~ hectare) at 500 plants per house this averages 10890 plants per acre

7

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

It may be 61 interest t9 d~tehnine a~ just whatmiddot price (or w~ge ate or yield) the operation will break even in figure 3 (data from table 4) the curves shm the minimum price required for various yields so as not to lose money (break-even points)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

~

11

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

Cropping sChLulCS usually found are one crop per year (spring) and two crops per year (spring and fall) Fall crops are typically set in the houses in September and harvested pound)orn mid-October through December Spring crops are set in Janu-ary and h~rves ted from Harch into July These two cropping sche~ules in addition to the choice of house design make up management systems from which the grower must plan his operation

i In this study each of the above management systems was

considered and ~h~e1 comp~redmiddot Profitability of -each system was determined by deriving current costs Input coefficients from ARS research along with prices from northeast Georgia l sources were used in sefting up the budgets

Costs

Table 2 shows I the production costs for an BOOO-squareshyfoot operaton Except for the polyethylene when it is used as a covering th~s~ costs are applicable -to all systems Since the useful rife of polyethylene is normally just 1 ye_ar it is considered a production cost while fiberglass aild glass are considered fixed costs

Table 3 gives the estimated iriitial capital investment required for the rpodel plastic greenho~se operation These data are blt~sed on Ia survey of grmvers in the Te~n_essee Valley items d~r~ctly related_ to the number of plants (eg string and lclips) are adjusted to ref-lect the number of plants used inthis r~port With the exception of the strueture itself a1l items are applicable to each system It should be noted that this schedule depiets a complete modern ope~~tion ~t new costs

Assuming an interest rate of 85 percent on half of the investment for boih capitai a-hd produc_tion costs 40- percent tax assessment at 30 milis 05 percen~ for insurance and 1 pereen~ for repairs enterprise budgets for each syst~em and cropping schedule lean be derived as shown in table 4

Estimated Profits and Break-even Poirits

the three- structures~ The profits are the retur_l_s exp_ected at each price For examplcent f~r one crop annually in the pl~st-ic house at a wage rate of $250 per hour and an averlge annual yield of 13 pounds per plant negative profits are shown at prices of $45 per pound and less while $50 per pound are required for positive profits (to the nearest $05) For two crops per year the yield per plant is the total weight for both crops (yield per space occupied by one plant) Tomato prices in the two-crop schedule1are average prices for both crops (each crops price weighted by that crops percentage of its average yield to total annual yield)

It may be 61 interest t9 d~tehnine a~ just whatmiddot price (or w~ge ate or yield) the operation will break even in figure 3 (data from table 4) the curves shm the minimum price required for various yields so as not to lose money (break-even points)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

~

11

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

the three- structures~ The profits are the retur_l_s exp_ected at each price For examplcent f~r one crop annually in the pl~st-ic house at a wage rate of $250 per hour and an averlge annual yield of 13 pounds per plant negative profits are shown at prices of $45 per pound and less while $50 per pound are required for positive profits (to the nearest $05) For two crops per year the yield per plant is the total weight for both crops (yield per space occupied by one plant) Tomato prices in the two-crop schedule1are average prices for both crops (each crops price weighted by that crops percentage of its average yield to total annual yield)

It may be 61 interest t9 d~tehnine a~ just whatmiddot price (or w~ge ate or yield) the operation will break even in figure 3 (data from table 4) the curves shm the minimum price required for various yields so as not to lose money (break-even points)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

~

11

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

APPENDIX

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

I bull

where y = yield per plant (13 lbs)

20

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

the three- structures~ The profits are the retur_l_s exp_ected at each price For examplcent f~r one crop annually in the pl~st-ic house at a wage rate of $250 per hour and an averlge annual yield of 13 pounds per plant negative profits are shown at prices of $45 per pound and less while $50 per pound are required for positive profits (to the nearest $05) For two crops per year the yield per plant is the total weight for both crops (yield per space occupied by one plant) Tomato prices in the two-crop schedule1are average prices for both crops (each crops price weighted by that crops percentage of its average yield to total annual yield)

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

APPENDIX

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

are and

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

I bull

where y = yield per plant (13 lbs)

20

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

are and

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

I bull

where y = yield per plant (13 lbs)

20

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

Short (4) where average costs and returns are also presented Extrapolating these data to the size of greenhouses in the Southeast and to 1977 costs shows production co_sts of $12000 for a glass greenhouse with two crops per year Average depreciation expenses in the report are $750 which would probably explain why Ohio growers are still prof-iting This is less thanone-third what one would expect and shows that in the survey many growers_ have already paid off their capital costs It is unclear as to how many Ohio gr-eenhouse operators would be in business today if 1hey we_re amortizing establishment costsmiddot at todays prices Ohio showeq a 33 percent decrease in the number of producers between 1959 and 1969 perhaps due in part to the high cost of neltl construction

The desert Southest is another area where greenhouse tomato produc~ion J1~s shm-m promise Capital costs are about the same as in other parts of the country but heating requirements are less On the other hand markets are distant so shipping costs are higher

FURTllER CONSIDERATIONS

This report presents the economics of greehnouse tomato production in the Southeast This form of agriculture is a very demanding and expensive operation A final consideratiol by anyone concerned with greenhouses whether growers extension personnel or policymakers should be the existence of sales 6~tlets Hith annual grower costs for Florida winter tomat~~s averaging between $14 and $19 per pound (1) and greenhouse tomatoes averaging over $40 per pound promoters and prospective operators should carefully evaluate the market before investing in the business ]j

Marketing the crop is the area in which most greenhouse operators fail A thorough understanding of the marketing channels available is a necessity when promoting any form of greenhouse operation Among the usual options are wholesalers retailers roadside or farm stands and doorshyto-door rou tes

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

the case of the plastic greenhouse gives (combining

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

APPENDIX

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

where y = yield per plant (13 lbs)

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields

Th~ TI)e~hod5 for deterin~riirig profits and break-even point~ are presented in the appendix Readers can estimate their own equations if their costs differ remarkably from those- presented here following the procedure in tbe appendix

ECONOMlcCS OF OTHER PRODUCING REGIONS

The costs of establishing a new greenhouse toma_to operation irt the Southeast are high and producers frequently are unable to recover these costs This situation appears to be nationwide

Dhillon and Kirschl_ing (~) expanded ~ 1969 survey_ of gro_wers in New Jersey to estil1ate cost and prof-it functions At that time the indu-strYwas very small in the State but has gr6wn considerab~y since The break-even price at that time for a plastic greenhouse with one crop permiddot year 13 pounds of tomatoes per plant and wages of $250 per hour was $48 per pound Product~on metnods have probably become mor~ efficient in the 8 years since this survey but costs of (tiel ~nd chemicals have nearly doubled so the break-even price has probably not decreased much if any

Ohio was the largest ~single greenhouse tomato grower in the United States with 57 percent of the tota-i greenhouse area in 1969 the date of the last agricultural census Growers have had successful operations there for 50 years A i972 survey of Ohio growers is reported by Duvick anltl

Produce wholesalers complain that in order to handle abull product a steady supply must be available Individual

1 Figure 2 shows how timing of greenhouse toma to production and sales could help compensate for this cost differential

15

greenhollse tomato growers frequently cannot guarantee this thus wholesalers may not want to add the item to their inventories Therefore growers should visit several wholesalers before assllming any Itlholesaler will buy the crop

Small producers might well consider selling direct to retailers Surveying produce managers in local supermarkets is highly recommended for those choosing this option Marketing through local stores has the advantages of not requiring distant delivery and smaller quantities are usually preferred by the stor~

Direct selling to the public is a frequently chosen method In considering this method sales costs both in real terms and in lost opportunity time for other endeavors should be considered

A combination of sales outlets can also be employed ~fuichever is chosen the additional costs of selling [lust be considered These include transportation time and any storage required Liner and Banadyga (~) give a rough figure of 5 cents per pound to estimate the cost of getting the fruit from the grower to the buyer For an individual who sells his product at the farm and has little or no alternative use for his labor this estimate is probably high On the other hand it is low for someone who only operates a small business and delivers to his customers

In conclusion the intensity of greenhouse culture is unlike anything else in crop agriculture and requires great managerial skills patience and hard work from the farmer Opportunities do exist for someone willing to devote the time to establishing marketing channels and managing the many facets of the business

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

Derivation of Profit and Break-even Equations

JO derive a profit equation total costs (TC) were broken into three categories

(1) Fixed costs (Fe) include depreciation of the capitalgoods interest on capital investment taxes insurance and maintenance and repair Total fixed costs do not depend on the cropping schedule (For the plastiC greenhouse total annual fixed costs equal $3878)

(2) Crowing costs (Ge) include production expenses interest on production expenses and the value of the labor required to grow the crop If 760 labo-r hours are attributable to growing each crop total annual growing costs for the plastic greenhouse in terms of wage rates equa-shy

$4980 + 164 + 760w = $5144 + 760w (for the spring crop) and

$8572 + 297 + l520w $8869 + l520w (for two crops)

(3) Harvesting and packing costs (HPC) vary wtth the number of plants grown and the yield per plant They are the total of the harvest labor requirement (in hours) times the hourly wage rate plus the packing cost Harvest labor equals the hours required per pound picked times the number of plants times the yield per piant packing cost equals the cost per pound t-imes the number of plants times the yield per plant1

Assuming 2000 plants are grown per -c~op two hours are required to pick and pack 100 pounds (1) and containers cost $150 per 100 pounds of tomatoes the harvesting and packing cost per crop for each system is

(02) (2000)yw + (01) (2000)y = 20(2w+l)y

where w hourly wage rate in dollars and

y annual yield per space occupied by one plant (pounds)

19

Summing the three components gives the total cost (TC)

TC = FC + GC + HPC

which in terms)

the case of the plastic greenhouse gives (combining

TC $9022 + 760w + 20(2w+1)y (for the spring crop) or

$12747 + 1S2Ow + 20(2w+l)y two crops)

(for

Total revenue (rR) is equal to the amount of production in pounds times the average annual selling price This may be expressed in terms of variable yields and prices as

TR = 2000yp

where y = total annual in pounds as

yield per plant before and

p average annual selling price This function assumes only one grade of fruit

Entrepreneurial profits (IT) difference between total revenue

are and

defined as the total cost

n = TR - TC

or in simplified form plastic greenhouse-shy

for the data in the model and the

n = 20(100p-2w-l)y - 760w - $9022 (for the spring crop) or

20(100p-2w-l)y - 1S20w (for two crops)

- $12747

The break-even point is computed by setting the profit function equal to zero and solving for the desired variable For example the break-even price for the plastic greenhouse and one crop per year is $048 per pound and is based on the equation

1 p = y(J8w+4S1l) + 02w + 01

I bull

where y = yield per plant (13 lbs)

20

r

w =wage per hour ($250) and

p average annual price per pound

The same equation can be manipulated to show break-even yields andor wage rates However care must be exercised when interpreting results For example the break-even prices in figure 3 are the average annual prices which in the case of both a fall and spring crop would be the average of the fall price and the spring price weighted by the respective yields
