Green Revolution led to an increase in the production of food grains. With the use of modern technology, extensive use of fertilisers, pesticides and HYV seeds there was a significant increase in the agricultural productivity and product per farm land. In addition, the spread of marketing system, abolition of intermediaries and easy availability of credit has enabled farmers with greater portion of marketable surplus. All these factors enabled the government to procure sufficient food grains to build the buffer stock and to provide cushion against the shocks of famines and shortages.
