The Green Revolution which is the New Agricultural Strategy (NAS) is composed of dwarf High Yielding Varieties (HYV), fertilizers, pesticides and new efficient water management techniques etc.
These are the result of scientific development. “This scientific development was made possible by Norman E. Borlaug of Rockfeller Foundation and many other agricultural scientists.
The Rockfeller Foundation established International Rice Research Institute (IRRI) at Los Banos in 1962. All improved varieties prefixed by I.R. owe their origin to IRRI.
The Government of India arranged for importation of Sonara 64 and Lerma Rajo 64 (wheat varieties) to accelerate production. With this, the year 1965 marked the year of change in Indian farming. Besides, many countries in the world started adopting the HYVs and this change is designated as Green Revolution.
ADVERTISEMENTS:
The word revolution implies
(i) A fast change in some phenomena, the change is so fast that it is well marked.
(ii) The impact of the change is felt over a period of time and brings about certain fundamental changes, “when we add the prefix “Green” to the word Revolution” and coin the phrase “Green Revolution”, thus, it refers to well worked improvement in agro-production in a short period.”
(iii) A higher level of agricultural production over a fairly long period of time.
