An evapotranspiration model of a paddy field was proposed based on the published reports on net radiation measurement. This led to the formula : E=0.0105・S, where E is potential evapotranspiration (mm・day^<-1>) and S is incident solar radiation (cal・cm^<-2>・day^<-1>). The evapotranspiration computed from the equation was found to be in good agreement with measured evapotranspiration data. The potential evapotranspiration rate was also related to U.S. class A pan evaporation rate as : E=0.93×pan evaporation. The model was then applied to 10 year's weather records at Los Banos, Philippines to compute climatic water balance. Average monthly water requirements of paddy rice crops in the Philippines were estimated at 180 mm for the wet season and 270 mm for the dry season.
