  • The System of Rice Intensification (SRI) was developed as a methodology aimed at increasing the yield of rice produced in irrigated farming without relying on purchased inputs. Its main elements were assembled in 1983 by the French Jesuit Father Henri de Laulanie in Madagascar after 20 years of observation and experimentation.[1] However, systematic evaluation and then dissemination of the system did not occur until some 10-20 years later. The productivity and merits of SRI have been debated between supporters and critics of the system since 2004, but the controversy has waned in recent years.

  • The world record yield for paddy rice production is not held by an agricultural research station or by a large-scale farmer from the United States, but by Sumant Kumar who has a farm of just two hectares in Darveshpura village in the state of Bihar in Northern India. His record yield of 22.4 tons per hectare, from a one-acre plot, was achieved with what is known as the System of Rice Intensification (SRI). To put his achievement in perspective, the average paddy yield worldwide is about 4 tons per hectare. Even with the use of fertilizer, average yields are usually not more than 8 tons. (...)
