Roles of Science And Technology in Agriculture

Science can be defined as knowledge obtain through the observation and testing of facts which are arranged in an orderly manner. Technology is the application of specific knowledge to production. Technology increase efficiency, thus providing high result from minimum effort.

The role of science and technology can be considered under the following:

  1. Farm power and machinery: Through the aid of science and technology there has been invention of various kind of machinery like tractor, plough, harrow, cultivator, harvester etc. farmers have been given loans by both federal and state government to purhase agricultural machinery.
  2. Production of chemicals, fertilizers: The development and production of chemicals and organic fertilizers can be seen as a direct result of the effect of science and technology. Different types of fertilizers and liming materials have been developed.
  3. Harvesting, processing and packaging: Science and technology has develop machine that can harvest, process and pakage various crops.
  4. Agricultural Research: Scientific research into agriculture has developed efficient farming systems and crops which are yielding and resistance to some pests and diseases.
  5. Transportation and communication: Transportation which is vital to the growth of agriculture has been greatly improved through science and technology. The contraction of communication network such as roads, railways and canals helps to link the village to another and helps the farmers to transport farm products to the cities.
  6. Pests and Disease Control: Damage caused by pest and diseases to crops and animals has been a big problems to farmers.
  7. Storage facilities: As a result of scientific inventions, farmers can now store their agricultural products for a long time.

Factors Affecting The Introduction of Science And Technology.

Several factors affect the introduction and adoption of science and technology in agriculture. They include

  1. Availability of funds.
  2. Availability of lands
  3. Willingness of the farmer to adopt science and technology.
  4. Education and research.
  5. Availability of marketing facilities.


  1. List 5 areas of improvement in Agriculture through Science and technology.
  2. List 3 factors affecting the introduction of science and technology.
