Green Revolution refers to the process where the production of crops increased many-fold. The use of modem science to improve agricultural practices made this possible.
Scientist came up new chemical fertilizers, herbicides and pesticides. The fertilizers helped to increase yield of crops by providing more nutrients. All these steps helped to increase the yield of crops.

Another positive step was the development of high yielding varieties of crops. The technique of multiple cropping was also introduced. This was the growing of two or more crops in the same field during one year.
