Green revolution
Introduction
The great increase in production of food grains (rice ans wheat) due to the introduction of HYV, तो the use of pesticides and to better management techniques
Components of green revolution

They were popularly called the Dwaft variety of seeds, with the help of repeated mutation
These seeds were non photosynthetic, hence nom dependent on sun rays for targeted yields
Chemical fertilizers
Irrigation

Geopolitical factors
Socio-economic factors
Infrastructure factors
Economic factors
Technological factors
Soil, landforms, precipitation, moisture, altitude etc
Food habits, festivals, traditions etc
Irrigation, transport, storage, trade and marketing, post harvest handling and प्रोसेसिंग
Financial resources, land ownership, size and type of land holding, household needs of food, fodder, Fuel, fibre and labour aviablity
