What is marketed surplus?

The Green Revolution has made India self-sufficient in food grains. The farmers sell their production in the open market. The portion of the agricultural produce which is sold in the market by the farmers is called marketed surplus. According to the famous economist C.H. Hanumantha Rao, a good proportion of the rice and wheat produced during the Green Revolution period was sold by the farmers in the market. As a result the price of food grains declined. The Green Revolution enabled the government to procure sufficient amount of food grains to build a stock, which could be used in times of food shortage.
