Q1. What is the approximate time period of second phase of the green revolution in India?
- (a) mid-1970s to mid-1980s
- (b) mid-1980s to mid-1990s
- (c) mid-1970s to mid-1990s
- (d) mid-1950s to mid-1960s
Answer & solution
Answer: (a) mid-1970s to mid-1980s
The Green Revolution in India had two main phases:
First Phase: mid-1960s to mid-1970s - Focused on wheat in Punjab, Haryana, and western UP using HYV seeds, fertilisers and irrigation.
Second Phase: mid-1970s to mid-1980s - Extended to rice and other crops, spread to more states like AP, Tamil Nadu, and Maharashtra.
Why other options are wrong:
mid-1980s to mid-1990s - This was a post-Green Revolution period.
mid-1970s to mid-1990s - Too broad; does not precisely describe the second phase.
mid-1950s to mid-1960s - This predates the Green Revolution.
