The growth rates of area, production and yield of foodgrains in India can be divided into two broad periods – the period 1949–50 to 1964–65, signifying the pre-green revolution period, and then after omitting two drought years 1965–66 and 1966–67, the second period of 1967–68 to 1996–97 represents the post green revolution period. The main impact of green revolution was on wheat, as production increased by 300 percent. High Yielding Varieties of wheat, rice, pulses, oilseeds and sugarcane were development under Green Revolution in India.
