The Green Revolution in the late 1960s introduced the Indian farmers to cultivation of wheat and rice using hig vielding varieties (HYVs) of seeds. Compared to the traditional seeds, the HYV seeds promised to produce muc greater amounts of grain on a single plant. As a result, the same piece of land would now produce far large quantities of food grains than was possible earlier. HYV seeds, however, needed plenty of water and also chemic ertilisers and pesticides to produce best results. Higher yields were possible only from a combination of HY eeds, irrigation, 'chemical fertilisers, pesticides, etc.

Farmers of Punjab, Haryana and Western Uttar Pradesh were the first to try out the modern farming metho n India. The farmers in these regions set up tube wells for irrigation, and made use of HYV seeds, chemic ertilizers and pesticides in farming. Some of them bought farm machinery, like tractors and threshers, whic nade ploughing and harvesting faster. They were rewarded with high yields of wheat.

n Palampur, the yield of wheat grown from the traditional varieties was 1300 kg per hectare. With HYV seed he yield went up to 3200 kg per hectare. There was a large increase in the production of wheat. Farmers now ha greater amounts of surplus wheat to sell in the markets.
