- 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.
