Explanation:
The Green Revolution, or Third Agricultural Revolution, is a set of research technology transfer initiatives occurring between 1950 and the late 1960s, that increased agricultural production worldwide, particularly in the developing 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 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.
The great increase in production of food grains due to the use of high -yielding varieties , pesticides and better management techniques .
Merits of green revolution :-
♥ Higher yield due to the use of HYV seeds.
♥ Machines like harvesters and tractors have made ploughing and harvesting faster and easier .
♥ Higher yield enabled farmers to sell the surplus food in the market and earn more .
♥ Pesticides and insecticides are able to protect the crops from pests and insects .
♥ A good irrigation system is able to enhance crop production .
Demerits of the Green Revolution
♥ Loss of soil fertility due to increased use of chemical fertilisers.
♥ Continuous use of groundwater for tubewell irrigation has reduced the water table below the ground .
♥ The chemical fertilisers , easily soluble in water can dissolve in the groundwater and pollute it .
♥ They can kill bacteria and other micro -organisms helpful for the soil .
♥ Excessive use of fertilisers can also make the soil alkaline and unfit for cultivation.
