Answers
The Green Revolution, or the Third Agricultural Revolution, is the set of research technology transfer initiatives occurring between 1950 and the late 1960s, that increased agricultural production in parts of the world, beginning most markedly in the late 1960s
The initiatives resulted in the adoption of new technologies, including high-yielding varieties (HYVs) of cereals, especially dwarf wheat and rice. It was associated with chemical fertilizers, agrochemicals, and controlled water-supply (usually involving irrigation) and newer methods of cultivation, including mechanization. All of these together were seen as a 'package of practices' to supersede 'traditional' technology and to be adopted as a whole.
Answer:
Green Revolution was an initiative started in 1960's which was started to increase in production of food grains (especially wheat and rice) by using HYV seeds , machinery and plenty of water.
The green revolution led to high productivity of crops through adapted measures, such as
1) increased area under farming,
(2) double-cropping, which includes planting two crops rather than one, annually,
(3) adoption of HYV of seeds,
(4) highly increased use of inorganic fertilizers and pesticides.
