Question

what is green revolution

Answer 1

Green Revolution was a package programme introduced to increase the yield per hectare of food grains by using fertilizers , insecticides , pesticides , machines and better methods of irrigation

Answer 2

the debate regarding the developmental strategy was not simply an economic one but also had political implications.while Nehru and the left of center group within the congress favoured  the state controlled and institutional strategy in agriculture, there was right of centre faction which was opposed to state control . they constantly criticized these programmes and attempted to water down the proposals . since this group was most powerful at the state level , they also ensured that most radical plans were not implemented properly.
                once it became clear that the existing strategy was not increasing food production , there was a shift to a different strategy between the years 1964-1967.this attempted to secure the cooperation of the state governments as well as increase in food productions . in a way it also reflected the changes in economic policy after Nehru 's death and also the changes in economic thinking.
