2. Application of Science and Technology to Agriculture

3.Factors Affecting the Application of Science and Technology in Agriculture

Sub-Topic:MEANING OF (I) SCIENCE AND (II) TECHNOLOGY INTRODUCTION The urgent need of man as a result of increase in the population world over is how to improve the quantity, quality and variety of his production. Any country that desires to develop its agricultural system must apply science and technology in the production, processing, preservation and marketing of food and fibre.

MEANING OF SCIENCE: Science can be defined as a branch of study which deals with the acquisition of knowledge through observations and testing out facts which are arranged systematically. Meaning of Technology: Technology is the application of scientific knowledge for the production of useful things. It is also means any innovation which will lead to improvement on the old ways of doing things.

Meaning of Science and Technology: Science and Technology refer to the acquisition and application of knowledge for the production of useful things with increased productivity from minimum effort. Technology started with the Industrial Revolution in Europe in the 18th century, with the introduction of power-driven machinery which took over the work originally done manually. This affected agriculture because machines were introduced to carry out agricultural activities (this is called Mechanized Agriculture/Farming). Through science and technology large hectares of land can be cultivated with better methods and increased yields. The advanced countries of the world like USA, Britain, Germany, France, China etc have succeeded in using machines to improve agricultural production thus increase their efficiency from little effort.


EVALUATION

1.What do you understand by science? 2.Define Technology 3.Differentiate between science and technology. 4.Where did Industrial Revolution started and when?

Sub-Topic2:APPLICATION OF SCIENCE AND TECHNOLOGY IN AGRICULTURE Science and Technology play major roles in the development of agriculture in developed and developing

countries by providing means of solving varied problems facing their farmers. The population of some

countries, particularly Nigeria is growing to an alarming proportion with the result that it has become

difficult to feed the people. To meet up with the food requirement of the growing population, such

countries must apply science and technology. The contributions of science and technology to

agricultural development are the following:

1. Farm Power and Machinery: Science and Technology have helped in inventing various machines

such as tractors, tractor-coupled implements, crop protection machines, milking machines,

incubators, processing machines etc to improve agric production.

Milking machine


Microscope Incubator Knapsack sprayer

2. Understanding of Climate (climatology) and weather (meteorology) conditions of different

places and consequently the type of farming system suitable for such places.

3. Improved Planting Materials: seeds and seedlings through Biotechnology (modification of living

things to make useful products that can be beneficial to man) like Tissue culture, Plant genetic

modification, Molecular breeding, Marcotting or Multiple Ovulation Embryo Transfer (in

animals).

4. Pest and Disease Control (management): A large percentage of farm products are lost annually

to diseases, pests and weeds. With the knowledge of science and technology, many chemicals

such as insecticides, fungicides, nematicides, fumigants, herbicides (weedicides) etc have been

developed to wage war against these enemies thereby prevent crop failure.

5. Plant and Animal Nutrition: With the knowledge gained from science, man has been able to

study the mineral content of the soil and the type of soil needed for crop growth. In addition,

the study of feeds and feeding has also revealed that the quantity and quality of livestock

products depend on the quality and quantity of feeds given to them.

6. Harvesting, Processing and Packaging: In large farms, crops are harvested with the use of

machines like combine harvester for cereal grain crops, root crop harvester for cassava, forage

harvester etc. Machines like shellers, threshers are used to process crops such as cereals and

legumes. Food packaging of agricultural produce helps to preserve produce from losses.

Through the application of science and technology, food items can be packed in cans, plastic

bags for easy storage or sale.


Rice harvester Wheat harvester (combine harvester)

Wheat harvester Wheat harvester

Cotton harvester Grain harvester

7. Storage of Agricultural Produce: One of the challenges facing farmers is how to store their farm

produce as soon as they are harvested. Lack of good storage facilities and methods have caused

serious losses of agric productsvia pests, diseases and even the weather. However, with the help

of science and technology, many storage facilities have been invented to reduce the loss caused

by the spoilage pests and micro-organisms. Storage of farm produce has been encouraged in


Nigeria by the establishment of a special research institute, known as the Nigerian Stored

Products Research Institute (NSPRI), with the headquarters based at Ilorin in Kwara state.

8. Transport and Communication: Transportation makes the distribution of farm produce to

different markets for sale. It makes both internal and external trade easy. Different types of

communication equipment have been invented such as Radio, TV, Newspaper, Journals,

Magazines,Cellular telephones, The Internet (Google, Wikipedia, African Agriculture) etc for easy

dissemination of important information about various modern agric practices developed in

research centers for the benefit of farmers in the rural areas.

9. Plant and Animal Improvement: The science of plant and animal breeding has made it possible

to cross plants or animals of different desirable qualities to produce hybrids which are high

yielding and resistant to some common pests and diseases.

10. Water Supply: Agricultural production depends on natural water which may not always be

sufficient. With the help of science and technology bore holes, deep wells water reservoirs,

dams and irrigation systems have been constructed to supply water to the farms and villages.

With this farming can be done throughout the year in many of the drier areas.

The diagrams above illustrate sprinkler irrigation

11. Information and Communication Technology (ICT) for Agriculture: This involves acquiring

agricultural information by using computers, fixed and mobile telephones, listening to

agricprogrammes on radio, watching programmes on TV or videos showing the best ways of

growing crops, taking care of livestock or even selling agricultural produce.


12. Agricultural Research Centres: The purpose of conducting agric research is to study and

understand the major problems facing farmers and other people involved in crop farming,

livestock, fisheries and forestry production in different areas and how to develop ways of

reducing the problems identified.An agricultural research institute plays major roles in the

application of science and technology to agriculture and is intended to develop new ways of

practicing agriculture and thereby improve its production.

WEEK 2 DATE: TOPIC: ROLES OF GOVERNMENT AGENCIES IN AGRICULTURE CONTENT:1. Meaning and Forms of Government Agencies 2.Roles of Government Agencies in Agriculture

Sub-Topic 1: MEANING OF GOVERNMENT AGENCIES Agency means an administrative division or department (within a government) providing a particular service for a state. Government Agencies are the administrative departments responsible for development of agriculture in the rural areas in order to boost food production.

FORMS OF GOVERNMENT AGENCIES

The government agencies in agriculture include the following: 1. Farm Settlement Scheme 2. Agricultural Development Programme/Project (ADP) 3. River Basin Development Authority and Rural Development Programmes 4. Operation Feed the Nation, Green Revolution and School-to-Land Programmes 5. Agricultural Loan Scheme and Subsidy on Agricultural inputs 6. Farm Insurance Scheme 7. National Fadama Development Project (NFDP) 8. National Agricultural Technical Support Project (NATSP) 9. National Agricultural Research Institutesgricultural Training Institutes

Sub-Topic 3:ROLES OF GOVERNMENT AGENCIES IN AGRICULTURE Farm Settlement Scheme: This program first started in the former Western Nigeria in 1959 with the aim of increasing agricultural production through the development of modern farming systems; discouraging young school leavers from migrating to the cities in search of office and factory jobs by providing them with necessary equipment for farming after they might have been trained in farm institutes for about two years. The diagrams below show different settlements.

AGRICULTURAL DEVELOPMENT PROGRAMME: It is a set of rural based agricprogrammes established with emphasis on improving infra-structural facilities especially rural roads, rural electricity and rural water supply which will lead to increase in agricultural production and thereby improving the living standard of the farmers.


RIVER BASIN DEVELOPMENT AUTHORITIES AND RURAL DEVELOPMENT PROGRAMMES:

These were set up in many states of the country principally to cultivate the land and help the farmers with the production and marketing of agric produce from the farm. They also carry out rural development by providing rural farmers with infra-structural facilities.

AGRICULTURAL LOAN SCHEME AND SUBSIDY ON AGRIC INPUTS: State and federal governments have established loan/credit schemes to farmers through commercial banks at low and considerable interest rates for agriculture. This is repayable assistance. Subsidy has been provided to farmers (in cash or kind) for the purchase of agricultural inputs such as fertilizers, fungicides, insecticides, herbicides and improved seeds at considerably reduced rates. This is non-repayable assistance.

OPERATION FEED THE NATION; GREEN REVOLUTION AND SCHOOL-TO-LAND PROGRAMMES:These three programmes were introduced by the former military presidents-Lt Gen OlusegunObasanjo (1976); AlhajiShehuShagari(1980)and Gen MuhammadBuhari (1984) respectfully to encourage people to farm and return to their abandoned farms.

NATIONAL RESEARCH INSTITUTES: Research is an advanced stage of study which deals mainly with discovering the unknown by careful and diligent search (i.e.the application of science and technology) and their discoveries are adopted by the farmers and other people involved in agriculture to improve the methods and practices they use thereby increase food production.

NATIONAL AGRICULTURAL TECHNICAL SUPPORT PROJECT (NATSP): This is a nationally coordinated programmes designed to assist in the development and dissemination of agricultural innovations (technologies) to small scale farmers through regular field training by agricultural extension agents.

NATIONAL FADAMA DEVELOPMENT PROJECT (NFDP): This is generally known as Fadama II and is a World Bank assisted project aim at assisting Fadama resource users to make them economically successful. It also supports production, processing and marketing of crops, livestock and fisheries in addition to development of rural infrastructures; acquisition of agro-processing equipment, tools and vehicles; settling conflict between farmers and pastoralists thus save the wanton destruction of lives and farm produce.

AGRICULTURAL TRAINING INSTITUTES: In Nigeria, efforts have been made to establish several agricultural schools, colleges and universities to train and develop people with adequate agricultural science knowledge and skills required for agricultural development. The faculties and universities also conduct research to


develop improved crop/animal varieties that are high yielding and resistant or tolerant to pests and diseases. This is to achieve food security and self sufficiency in industrial raw materials.

ICS-NIGERIA: The Information and Communication Support for agricultural growth (ICS-Nigeria) project is involved in the dissemination of agric information to farmers through locations called ICS Resource Centres which are located in the state ADP headquarters. They support and sponsor radio programmes as well as production of materials such as extension guides, booklets, pictures, posters and other materials.

FARM INSURANCE SCHEME:

Insurance, legal contract, protects people from the financial costs that result from loss of life, loss

of health, lawsuits, or property damage. Insurance provides a means for individuals and societies

to cope with some of the risks faced in everyday life. People purchase contracts of insurance,

called policies, from a variety of insurance organizations. Almost everyone and every

organization in modern, industrialized countries buy insurance. For instance, laws in most states

require people who own a car to buy insurance before driving it on public roads. Lenders require

anyone who finances the purchase of a home, car or any other property with borrowed money to

insure that property. Business partners take out life insurance on each other to make sure the

business (agric) will succeed even if one of the partners dies
