Special emphasis was laid on high-yielding varieties (HYV) of seeds during the green revolution. The success in this field was achieved in the Kharif crop of 1966, when high yielding seeds varieties were adopted. High yielding seeds varieties were imported from Mexico for wheat. Greater success was achieved in wheat crop through the use of high yielding seeds. The Father of Green Revolution in India is considered to be Dr. M.S.Swaminathan, while in the global context, this credit goes to Norman E. Borlaug.

Thus, the new strategy was related to HYV seeds and as a collective package which was related to the total economy.

The strategy for green revolution in India has been divided into two stages:

• First stage is called the stage of centralization : It was limited to the crop of wheat and rice. In this stage, the productivity of wheat increased rapidly, and so it is also called the stage centralized on wheat crop. 
• Second stage : A group of 5 crops was included in this stage. This included wheat, rice, millets, barley and maize.The programme was implemented in other parts of the country, and so it is also called the ‘stage of decentralisation’.The emphasis was given on ‘dry farming’.

Success or Impact of Green Revolution : 

1. The productivity of wheat per hectare increased from 851 kg to 3075 kg. For this, it was called “Wheat Revolution”. 

2. Increase in use of fertilizers. 

3. Irrigation facilities expanded rapidly. 

4. The use of machines and equipment in agriculture received a major and extensive boost, which transformed the traditional form of agriculture to a modem form. 

5. Use of pesticides and high-yielding varieties of seeds also increased extensively.

Setbacks of Green Revolution : 

1. The greatest effect of green revolution was on wheat, but the green revolution was ineffective on crude grains, pulses and oil seeds. 

2. The effect of green revolution remained limited to some regions only, which started the process of unbalanced development in agricultural development. 

3. The problem of agricultural finance persisted mainly in Indian economy. 

4. Only educated and prosperous farmers could reap the benefits of the new agricultural strategy. 

5. Green Revolution has ecological effects too, i.e. increase in salinity, soil erosion, problem of waterlogging, lowering of ground level etc. 

6. Only big farmers could benefit from agricultural subsidies given by the government.

Thus, we can infer that the effect of green revolution was limited to certain regions and big farmers only.
