The green revolution refers to an unexpected and revolutionary spurt in the production of crops. A significant increase in agricultural productivity resulting from the introduction of a high yield variety of seeds, the use of pesticides, and improved management techniques. The green revolution did not succeed in all the states. Only a few states like Punjab, Haryana, and crops like rice were major beneficiaries. There wasn't an increased production of all food grains and crops. It focused mainly on wheat and rice.
