Norman
Uphoff, Cornell professor of government and international agriculture,
spoke on what has been learned about the System of Rice Intensification
(SRI) around the world April 5 at the closing session of Cambodia's
fourth annual national farmers’ conference at the Royal Agricultural
University in Phnom Penh. The session was presided over by Cambodia's
minister of agriculture, forestry and fisheries.
In
his remarks at the conference, the minister reported that use of SRI
methods in Cambodia has expanded from small trials done by 28 farmers in
2000 to more than 200,000 farmers. Yields are 50 to 100 percent higher
for paddies using SRI, and those yields are achieved with lower
production costs. As a result, he said, farmer incomes from rice
production can be doubled or more with SRI.
Cambodian
institutions learned about SRI methods from information provided by the
Cornell International Institute for Food, Agriculture and Development
(CIIFAD) when Uphoff was serving as CIIFAD director, between 1990 and
2005. CIIFAD now hosts the SRI International Network and Resources
Center, for which Uphoff serves as senior adviser.
In
his remarks, Uphoff underscored a range of SRI benefits for farmers
beyond achieving higher yields with lower cost, including crop
resistance to pests and diseases and greater toleration of climatic
stresses such as drought and storms. He also noted that SRI practices
are being adapted for other crops, including wheat, sugarcane, finger
millet and various legumes. Much of his talk elaborated on the
contributions that beneficial soil organisms can make to crop
performance.
