Answer 1

 green revolution is the great increase in production of food grains (such as rice and wheat) due to the introduction of high-yielding varieties, to the use of pesticides, and to better management techniques.

Answer 2

The Green Revolution, or Third Agricultural Revolution, refers to a set of research and the development of technology transfer initiatives occurring between the 1930s and the late 1960s (with prequels in the work of the agrarian geneticist Nazareno Strampelli in the 1920s and 1930s), that increased agricultural production worldwide, particularly in the developing world, beginning most markedly in the late 1960s.[1] The initiatives resulted in the adoption of new technologies, including:

...new, high-yielding varieties(HYVs) of cereals, especially dwarf wheats and rices, in association with chemical fertilizers and agro-chemicals, and with controlled water-supply (usually involving irrigation) and new 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.
