Assessment of economic returns by using a central pivot system to irrigate common beans during the rainfed season in Central Brazil

Irrigation improves yield, but can create conflicts with other water uses during dry periods. Based on this, the aim of this study is to assess the economic returns provided by irrigation of common beans during the rainfed season in Central Brazil. Common bean yield was simulated for 30 growing seasons using the crop model DSSAT-CROPGRO-Drybean, with parameters calibrated for the cultivar Perola. The yield simulations considered sowing dates...
