Why were the benefits of the Green Revolution restricted to few crops in initial stages of planning?
The Green Revolution was based on the use of High Yielding Varieties (HYVs) of seeds, which required reliable irrigation and financial resources to buy better inputs. Because of this, the Green Revolution was restricted to the more affluent states of Punjab, Andhra Pradesh, and Tamil Nadu. Further, the use of HYV seeds primarily benefitted the rice and wheat growing regions.
Thus, the benefit of the Green Revolution was initially restricted to few states and the crops of wheat and rice only.
