The objectives of this study were to prepare spatial database of physical land resources for irrigated agriculture and to assess land suitability for irrigation and develop suitability map for sugarcane and onion in Yetnora watershed. Environmental factors such as mean temperature, relative humidity, EC, ESP, CEC, calcium carbonate, soil depth, soil texture, pH, soil stoniness, water table depth, flood hazard, and slope were used to evaluate irrigation suitability. The study revealed that, 72.6% was classified as moderately suitable (S2); 9.2% was marginally suitable and 18.2% was rated as permanently not suitable (N2) for both sugarcane and onion production. Soil texture, ESP, and slope, were the major limiting production factors for both irrigated sugarcane and onion production. Generally, the study area is suitable for irrigated sugarcane and onion production under proper management, which can benefit the local community to meet the food demand.
