The Green Revolution is referred to as the process of increasing agricultural production by incorporating modern tools and techniques.
The Green Revolution spread over the period from1967/68 to 1977/78 and changed India’s status from a food-deficient country to one of the world's leading agricultural nations.
The components of the Green Revolution-
HYV Seeds- These are seeds are of better quality than normal quality seeds. Mr Borlaugh had been able to develop a seed which was raised in its nature of nutrients supplied to the different parts of wheat plant-against the leaves, stem and in favour of the grain. This made the plant dwarf and the grain heavier- resulting in high yield. These seeds were non-photosynthetic, hence non-dependent on sun rays for targeted yields.
The Chemical Fertilisers- The level of nutrients HYV seeds required could not be supplied with the traditional composites. That is why a high concentration fertiliser was required which could be given to the targeted seed only, the option was the use of chemical fertilisers - urea, phosphate, potash.
The irrigation- For controlled growth of crops and adequate dilution of fertilisers, a controlled means of water supply was required.
Chemical Herbicides and Weedicides- To prevent costlier inputs of fertilisers not being consumed by the herbs and the weeds in the farmlands, herbicides and weedicides were used while sowing the HYV Seeds.
Credit, Storage and Marketing- All the peripheral infrastructure were developed with the softer loans coming from the World Bank.
