Jawaharlal Nehru was the first Prime Minister of independent India from 1947 to 1964. He advocated for industrialization and promoted the "Green Revolution" which increased agricultural production through new seeds, fertilizers, and irrigation. Nehru established India's mixed economy model with both private and public sectors. Three quarters of India's population lived in rural villages as farmers during this time period. The "Green Revolution" helped India become self-sufficient in food grains by allowing farmers to triple their crop yields.
