Name the three Indian states, in which Green Revolution was introduced for the first time.

The Green Revolution was first introduced in Punjab, Haryana and Uttar Pradesh in the 1960s. Its main goal was to increase the production of food grains like wheat and rice using high-yield variety (HYV) seeds, chemical fertilizers, pesticides and advanced irrigation techniques. Punjab and Haryana, with their fertile land and strong irrigation facilities, became the leading states in adopting these modern farming methods. Uttar Pradesh also benefited significantly, helping India achieve self-sufficiency in food production. However, the Green Revolution had some negative environmental impacts, such as soil fertility depletion and a decline in groundwater levels. Despite these challenges, it played a crucial role in improving agricultural productivity and reducing food scarcity in India.
