绿色革命
The Green Revolution yielded great economic prosperity during its early years. In Punjab, where it was first introduced, the Green Revolution led to significant increases in the state's agricultural output, supporting India's overall economy. By 1970, Punjab was producing 70% of the country's total food grains, and farmers' incomes were increasing by over 70%. Punjab's prosperity following the Green Revolution became a model to which other states aspired to reach.
