Define green revolution. What are the main objectives of crop improvement?

Green revolution is the phenomenon of introducing High yielding variety of seeds and increased use of fertilizer and irrigation methods. It is aimed at increasing the production of food grains. It is done by employing better and advanced farming techniques.

Main objectives of crop improvement includes,

1. To achieve higher yield of crops by developing high yielding variety crops. This is done by using hybridization and cross-breeding.

2. To obtain better quality of crops. It includes improving baking quality in cereals and protein quality in pulses.

3. To make crops resistant to biotic stresses like insects and abiotic stresses like heat, salinity, cold.

4. To obtain desirable agronomic traits to sustain the various threats during the production process.

5. To develop crops more adaptable to the environment. This helps in stabilizing the crop production.
