Rice production in the Green Revolution period Generally, the development and adoption of new and modern varieties seemed to have more impact to the rapid yield growth from 1965 to 1980 than to any change in the production technology. Likewise, with the advent of the Green Revolution and the scarcity of and increasing cost of labor, research and development of mechanization technologies was vigorously initiated and the adoption of mechanized farming became eminent in the rice field. Before 1967, the increase of yield was more attributed to the increase of production area (53%); after 1967, the total production was due to the yield (76.5%) apparently due to the high yielding capacity of the newly introduced varieties. With proper seeds and cultural practices improved, the yield was boosted in 1975 from 1.75 tons/ha to 3.2 t/ha yield in 2002. Rice production during this period is considered as most progressive because of tremendous growth in crop productivity and significant changes in terms of rice production techniques and management. In this period, IRRI spearheaded in changing the landscape in rice, from the development and introduction of modern high yielding varieties to the intensive use of chemical inputs and machines to sustain high yields and double cropping system.
