Alternate Wetting and Drying (AWD) and System of Rice Intensification (SRI) Techniques for Sustainable Irrigated Rice Production

Date: June 8, 2017

Alternate Wetting and Drying (AWD) is a water-saving technology that farmers can apply to reduce their irrigation water consumption in rice fields without decreasing its yield. In AWD, irrigation water is applied a few days after the disappearance of the ponded water. Hence, the field gets alternately flooded and non-flooded. The System of Rice Intensification (SRI), which originated in Madagascar in the 1980s, also uses wetting and drying of the field in addition to agroecological cropping principles such as 7 day old seedlings instead of the 15-20 day seedlings and one seedling per hill instead of several per hill used in traditional rice growing practices, the addition of compost and/or fertilizer, and 2-3 mechanical weedings depending on weed pressure. Practitioners of SRI report significantly enhanced yields relative to best management practices with continuously flooded rice.
