"Green revolution experienced the success in two phases." Comment.
In the first phase (mid-60s to mid-70s), the use of HYV seeds was restricted to the more affluent state like Punjab, Andhra Pradesh, and Tamil Nadu etc. Further, the use of HYV Seeds primarily benefitted the wheat growing regions only. In the second phase (mid-70s to mid-80s), the HYV technology spread to a larger number of states and benefitted more variety of crops.
