The study looked at how agriculture in India has changed over the years. They analyzed data from 1967 to 2007 and found that farmers are growing more commercial crops instead of food grains. The area used for coarse cereals decreased, and pulses didn't do well. However, crop yield has increased since the late 1960s due to new technology, irrigation, and fertilizers. Rice and wheat saw big changes in some regions. Overall, better irrigation, normal rainfall, and more fertilizers have helped improve crop output in India.
