Presentation prepared for 2 nd National SRI symposium hosted by the State Government of Agartala, with cosponsorship of ICAR (DRD/DRR), CRRI, ANGRAU, NABARD, Tata Trust and WWF, October 3-5, 2007.
This field was harvested in March 2004 with representatives from the Department of Agriculture present to measure the yield. Picture provided by George Rakotondrabe, Landscape Development Interventions project, which has worked with Association Tefy Saina in spreading the use of SRI to reduce land pressures on the remaining rainforest areas. The Ministry of Agriculture technician who measured the yield reported this as 17 t/ha.
SRI is often hard to accept because it does not depend on either of the two main strategies that made the Green Revolution possible. It does not require any change in the rice variety used (genotype) or an increase in external inputs. Indeed, the latter can be reduced. SRI methods improve the yields of all rice varieties evaluated so far – modern and traditional, improved and local. The highest yields have been attained with HYVs and hybrid varieties (all SRI yields >15 t/ha), but ‘unimproved’ varieties can give yields in the 6-12 t/ha range when soil has been improved through SRI methods, so give the higher market price for these latter varieties, growing them can be more profitable for farmers.
Figures from a paper presented by Dr. Tao to international rice conference organized by the China National Rice Research Institute for the International Year of Rice and World Food Day, held in Hangzhou, October 15-17, 2004. Dr. Tao has been doing research on SRI since 2001 to evaluate its effects in physiological terms.
Two fields of rice growth with normal methods and 3-S. The phenotypical differences are evident, much as seen with SRI.
Picture provided by Mr. Shichi Sato, project leader for DISIMP project in Eastern Indonesia (S. Sulawasi and W. Nusa Tenggara), where > 1800 farmers using SRI on >1300 ha have had 7.6 t/ha average SRI yield (dried, unhusked paddy, 14% moisture content), 84% more than the control plots, with 40% reduction in water use, and 25% reduction in the costs of production.
Picture provided by Dr. Koma Yang Saing, director, Cambodian Center for the Study and Development of Agriculture (CEDAC), September 2004. Dr. Koma himself tried SRI methods in 1999, and once satisfied that they worked, got 28 farmers in 2000 to try them. From there the numbers have increased each year, to 400, then 2100, then 9100, then almost 17,000. Over 50,000 farmers are expecting to be using SRI in 2005. Ms. Sarim previously produced 2-3 t/ha on her field. In 2004, some parts of this field reached a yield of 11 t/ha, where the soil was most ‘biologized’ from SRI practices.
This picture from Sri Lanka shows two fields having the same soil, climate and irrigation access, during a drought period. On the left, the rice grown with conventional practices, with continuous flooding from the time of transplanting, has a shallower root system that cannot withstand water stress. On the right, SRI rice receiving less water during its growth has deeper rooting, and thus it can continue to thrive during the drought. Farmers in Sri Lanka are coming to accept SRI in part because it reduces their risk of crop failure during drought.

Picture from Elske van de Fliert, FAO IPM program in Hanoi. Rice plants come from the left and right fields behind the farmer, respectively, after the fields had been hit by a typhoon.

.…Since the success of the original two-year trials, the SRI method has been extended to more farmers in more regions throughout Laos. The national average rice yield in Laos is 3.27 tons per hectare. Using SRI, farmers have an average yield of 5.05 tons per hectare. This increase means there are fewer ‘rice shortage months’ every year... RICE REVOLUTION IN LAOS From Oxfam International webpage: http://www.oxfam. org/en/programs/development/ easia/laos_rice.htm
