Multiple regression analysis of impact of irrigation, area under cultivation, use of fertilisers and flow of credit on farm production

Agricultural output depends upon many factor inputs. Though it is largely dependent upon timely monsoon, the role of irrigation facilities and area under cultivation, proper use of fertilisers and flow of credit at cheaper interest rates play a vital role. In the present study it was found that the use of fertilisers was not giving the desirable results and it was due to improper ratio of different fertilisers. The output of food grains at present is quite satisfactory. The area under food grains, extent of irrigation and flow of credit have been important determinants of the farm output. Net irrigated area is less than 50 per cent of the gross cropped area even after 66 years of economic planning. Much of our agriculture is still dependent on monsoon. There has been extensive use of urea. Though the administered prices usually cause black marketing of the product, there has been bias in favour of it due to costlier phosphatic and potassium fertilisers. The soil fertility has been badly affected in areas of green revolution and other parts of the country due to improper admixture of NPK fertilisers during recent years.
