India achieved a fourfold increase in food grain production from 1952 to 2010 primarily through the Green Revolution, which introduced high-yielding varieties (HYVs) of crops, improved irrigation infrastructure, and increased the use of fertilizers and pesticides. Adoption of modern agricultural practices, mechanization, research and development in crop breeding, and better farm management techniques also played crucial roles in boosting productivity despite limited expansion of cultivable land area.
