Answer: The introduction of High Yielding Varieties (HYV) of seeds and the increased use of fertilizers, pesticides and irrigation facilities arc known collectively as the Green Revolution, which resulted in the increase in crop yield needed to make India self-sufficient in food grain.
Advantages of the Green Revolution
Green Revolution introduced a number of modern farming methods in India.
- Higher yield due to the use of HYV seeds.
- Machines like harvesters, tractors and threshers 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.
Disadvantages of the Green Revolution
- Loss of soil fertility due to increased use of chemical fertilizers.
- Continuous use of groundwater for tube well irrigation has reduced the water table below the ground.
- The chemical fertilizers, 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 fertilizers can also make the soil alkaline and unfit for cultivation.
