Accepting System of Rice Intensification (SRI) by Farmers in Rainfed Lowland Paddy Area of Cambodia

Abstract

System of rice intensification (SRI) is an environment-friendly and sustainable rice farming practice developed in Madagascar in 1980s under irrigated condition. Unlike the Green Revolution technology, which was widely applied in many developing countries after 1960s, SRI does not require additional chemical fertilizers or agrochemicals. Recently, SRI has been diffused not only in irrigated area but also in rainfed lowland paddy in Cambodia. It is significant, if SRI is confirmed to be effective in rainfed area, where green revolution technology is ineffective. The objective of the research is to analyze acceptability of SRI by farmers in rainfed lowland paddy area and illustrate reasons for acceptance or non-acceptance. Farming practice comparison test was conducted in the rainy season of year 2008 by six volunteer farmers in three villages of Prey Nheat commune, Kong Pisei district, Kampong Speu province in Cambodia. Each of these farmers’ rainfed lowland paddy plot was divided into two parts, SRI practices on one part and the traditional practice on the other.In year 2008, the farmers did not adopt all of the SRI principles but only for some. There was no significant difference between the yield of SRI and conventional practice. However, the farmers founded benefits from SRI, such as less labor and less seeds and they accepted SRI. The research indicates prospect of SRI in rainfed lowland paddy, since farmers can maintain at least the same level of yield with less resources and cost. It was also revealed that decreasing seedlings per hill has been an important motive for the farmers to change their farming practice.
