SCIENCE AND TECHNOLOGY IN AGRIC SCIENCE



ROLE OF SCIENCE AND TECHNOLOGY IN AGRICULTURAL DEVELOPMENT

Objectives: Students should be able to:
1. Explain the meaning of science and technology.
2. Identify and explain the various areas through which science and technology have contributed towards the development of agriculture.

Meaning of science and technology


Science can be explained simply as a field of study or a branch of knowledge which requires systematic study or method. Science deals mainly with the study of substances, animal and vegetable life. Technology is the application of scientific knowledge in industry. It is concerned mainly with construction and the manufacture or production of goods or materials.







How science and technology have helped agricultural development in Nigeria

1. Improvement of Crops and Animals Through the science of breeding,
'better quality of crops and livestock have been provided. These high quality plant and animal stocks have helped to raise the standard of living of the people.
Breeding simply involves the crossing of organisms which belong to the same species with the aim of obtaining better strains or varieties

2. Improved Plant and Animal Nutrition With the help of science, farmers are now able to produce crops by the use of artificial food substances (fertilizers). These fertilizers are added to the soil to increase the fertility and hence raise the level of crop production.
Also, different types of feeds are now available for different farm animals. The use of these feeds helps the animals to grow fast, healthy and produce very well.

3. Pest and Disease Control Science and technology have helped in the protection of plant and animal life. This has been achieved through the discovery of method* and production of chemicals and equipment for the control of pests and diseases of plants and animals.









4. Mechanization of Agriculture With the manufacture of different farm machines, most agricultural activities can now be done with machines.
For example, the soil can be tilled with plough or harrow, large trees can be felled with the motor-saw, milking can be done with the milking machine, while chicks can be produced with the help of the incubator.

5. Improvement of Storage and Processing Facilities The manufacture of refrigerators, silos and others have helped in solving the problem of how to store agricultural products.
Also, farm produce can be processed into different forms which help to extend their availability and utility.


6. Construction of Roads The construction of good roads, especially in the rural areas has helped in the development of agriculture. Roads are important in the evacuation of agricultural produce from areas of production to the markets.

7. Construction of Irrigation Facilities Science and Technology have helped to solve the problem of lack of, or insufficient water in some parts of the country. This has been achieved through the construction of dams and boreholes which help to supply water for farm use.

8. Improved Farming Methods Science has helped greatly in changing agriculture from tire primitive approach to more modern and better approaches.Such modern approaches as crop rotation, soil and water conservation practices, intensive methods of rearing farm animals and others have resulted in increased quality and quantity of farm produce

The role of government in the application and technology in agriculture.
The government of Nigeria has been encouraging the of science and technology in agricultural production in the following ways:

1. Provision of farm inputs such as high yielding varieties of crops and animal stocks, chemicals, farm tools and machines others to farmers.

2. Provision of credit facilities and subsidies to farmers in order to acquire new technologies in agriculture.

3. Establishment of agricultural training institutions such as schools of agriculture for the training of personnels concerned with agricultural activities in the country.

4. Establishment of agricultural research stations which are concerned with providing scientific solutions to agricultural problems.

5. Training of personnels such as technicians who help to operate machines, extension workers who teach farmers modern tanning techniques, and so on.

6. Establishment of agro-service centres for hiring of farm machines.

7. Establishment of mechanized farms, which serve as models for local farmers to learn from.
