Definition of Green Revolution (GR):
When better and superior seeds are used; the fertilizers, pesticides,
herbicides and sprays are used; and the farm machinery like tractors,
harvesters, tube wells and threshers etc., are used to enhance the agriculture output and agri. productivity
all is given the name of Green Revolution (GR).
Thus because of GR, the high yielding seeds, fertilizers, agri. machinery
water and better technology will become available. Consequently, the production
function for any crop or crops will shift upward in agriculture sector leading
to increase the agri. output. It is shown with the Fig.
If we represent the production
function as Q = f (I) where I represents inputs
like labor and water, seeds and fertilizers. We suppose that Q = f (I) is a
traditional production function. If it shifts to Q = f (I/), it will represent
the modern production function. If due to greater use of inputs the yield rises
equivalent to the area ab or more than this, then we have green revolution.
The GR has been observed in India, Pakistan, Thailand and South American
countries during the late 60s and 70s when there was rapid increase in per acre
yield of the food grains. Such increase in agriculture production is due to GR.
Effects of Green
The GR will have the following effects.:
