VSC 602 Production Technology of Cool Season Vegetable Crops (2+1)PRODUCTION TECHNOLOGY OF CAULIFLOWER

IntroductionCauliflower is one of the most important Cole crop grown as vegetable throughout the world.Now it grown in both temperate and tropical areas.It is originated from wild cabbage B. oleracea L. var. sylvestris L.

Cauliflower Botanical name Brassica olerace var. BotrytisFamily Brassicaceae / CruciferaeChromosome number2n=18Edible part Curd

Origin B. oleracea var. botrytis L. is believed to have originated in Cyperus or somewhere in southern part of Europe around meditteranion coast.It is originated in the island of Cyperus from moved to Syria, Turky, Egypt, Italy, Spain and north western Europe (bosewell, 1949)

In middle 16th century first illustration description herbalist Dodoens (1544)18th century popularized Different types of cauliflowers is there

History Caulis latin cabbageFlori flowerBotrytis buddingIn introduced in India at 1822 by Dr. Jemson a botanist from Kew. (Saharanpur Northern plains) (Swarup and Chatterjee, 1972)


Botany Edible potion is the white curd like mass composed of a close aggregation of abortive flowers, developed on thick bunches of the inflorescence. This is called as curd.Curd is made numerous hypertrophic branch it terminate main stem and highly suppressed with no part of flower apparent there. (kato 1964)

Uses Cauliflower used to prepare dishesSeedling used for salads and greensCurd used for curries, soups and pickles.Curd is cut in to pieces, dried and preserved for off-season use.

Varieties and hybrids Cauliflower varieties are very responsive to temperature and photoperiod.Require specific temperature for their curd and development.According to temperature requirement varieties have been classified in 5 groups (Singh and Nath, 2011)

Climate Thermo sensitive cropOptimum temperature required range from 20 to 25 c in sep to Oct and 5 to 10 c during Dec to JanTropical type curd formation 20 to 25cTemperate annuals curd formation 10 cto 16c


At high altitudes the longer day length promotes much faster growth of the plant (Salter 1960)The optimum temperature for growth of young plants is around 23C and 1720C in later stages.

SoilIt can be grown in wide range of soil with good fertility.light soil are more sensitive to drought and therefore, adequate moisture supply is important.Light soil early crop, loam and clay soils mid and late season crops.

ContCauliflower is relatively more sensitive to deficiency of boron and molybdenum respectively it cause browning and whiptail. Also it has high requirement of magnesium.Magnesium deficiency appear in acid soil.

ContHigh ph reduces the availability of boroncauliflower require on an average ph range of 5.5 to 6.6ph and below 5.5ph it would be necessary to do liming at the rate of 4 to 8 tonnes/ha.

Seed treatment Prior to sowing seeds are treated with fungal culture of Trichoderma viride (4 g/ kg of seed) or Thiram (3g/ kg of seed) or to avoid damage from damping-off carbendazim (3g/ kg of seed) (pythium, Rhizoctonia) disease.Streptocycline 1.5g/kg of seed for control black rot or hot water treatment with 50 c for 30 minutes.

Nursery practices Early crop 500-600g/haMid and late crop 350-400gBed preparation The soil of the nursery beds should be reduced to the finest possible tilth before sowing and manuring FYM or Compost @10kg/m2Length is convenient and width 1m, height 30cm

Sowing method The seed sown thinly (15-20seed per 30cm) in rows and not more than 1.5-2cm deep.The rows should be 7cm apart.Seeds are covered after sowing with 0.5-1cm of soil.Mulching material (dry grass) can be used to cover the bed after sowing. It should be removed after seed sprouting(3-4 days),

After sowing the seedbed irrigate frequently using rose cane twice a day. And channel between the two beds watered alternate days or every third day.Watering should be withheld 3-4 days before transplanting so that seedlings get hardened.Before uprooting, the beds are thoroughly soaked water to facilitate to remove for transplanting.

ProtrayThe protrays of 98 cells are ideal for cauliflower seedling production. Around 600 Protrays are required for of 28,333 seedlings required for one hectare at a spacing of 60x45x45 cm in three row planting.

Protected nurseryRaise the seedlings in shade net house. A nursery area of 5 cents with slanting slope of 2% is required for the production of seedlings for 1 ha.Cover the nursery area with 50 per cent shade net and the sides with 40/50 mesh insect proof nylon net. Form the raised beds of 1m width and convenient length inside the nursery and above the beds, place the protrays.

Growing mediumThe sterilized coco peat @
