Rice is the world's most consumed cereal grain, making up the dietary staple food of more than 60 percent of the world's population. For agriculture dominated country like India, the assessment of rice yield is of utmost importance for policy makers in managing the food security and water resources. The present study evaluates the efficiency of Soil and Water Assessment Tool (SWAT) to simulate rice yield during both kharif and rabi seasons in Brahmani River basin, and subsequently, identifies the appropriate evapotranspiration estimation approach for accurate quantification of crop water requirement, and irrigation scheduling. | Evaluation of evapotranspiration methods for rice yield simulation in a tropical river basin
