The concept of ‘food security’ is fundamentally important, and for that reason, agriculture is important. The task of feeding its people has been perhaps the first priority of its rulers throughout history. As such, agriculture is considered to be the very basis of political and social stability of a nation since times immemorial.

Moreover, the agricultural sector plays an important role in the sphere of providing large scale employment to people. Large and moderately large farms employ workers to undertake the various jobs relating to cultivation of crops and care of farm animals. In most of the countries of the world, agriculture still remains the biggest sector responsible for the employing and feeding a large percentage of the population.

Agriculture is also important from the point of view of appraising the standard of a country’s development, based on the competence of its farmers. Poorly trained farmers cannot apply the advanced methods and new technologies. The prominence of science and technology in the development of agriculture is quite clear from the words of Deng Xiaoping – ‘The development of agriculture depends first on policy, and second on science. There is neither any limit to developments in science and technology, nor to the role that they can play in the field of agricultural growth’.
