Although agricultural engineering is a fairly new subject, its effect is being felt in India increasingly. In recent years it has contributed to agricultural production in the country both directly and indirectly. The number of modern machines used in agriculture is a fairly good index of the progress made during the four 5 year plans. And yet all this progress is insignificant as compared to that in USSR, USA, Japan, UK Canada, and Australia. This development has made two things clear: 1. That the Indian farmers are quick in adopting new methods and techniques and 2. That the Indian industries can manage as good machines as those abroad.
Agricultural engineering as defined by international institutions comprises of four main branches, (i)farm implements (ii)rural structures (iii)soil conservation, drainage, and irrigation and (iv)rural electricity.
Because of the peculiar local conditions the lack of electricity on a large scale, and the immediate utility of implements, agricultural engineering in India is more of agricultural implements and machinery. But in fact agricultural engineering is a very vast subject and may be defined as the application of the knowledge, techniques and disciplines of various fields of engineering to the solution of problems arising in the field of agriculture and rural living with the object of reducing labour, improving productivity and raising the standard of living of the farmer and increasing the overall earnings per worker.
The era of more intensive planning brought reorganisation on a wider scale. With the establishment of agricultural universities, several agricultural engineering colleges were established offering graduate and post graduate courses. The most important step has been the establishment of agro-industries corporations with the financial assistance of the Central Ministry of Agriculture. The main objectives of establishing these corporations have been to take over the supply and service functions of the departments of agriculture and to expand them. These agri-industries corporations have each a paid-up capital of 2-5 crores of rupees. They have taken over the existing government workshops also.
