Resumo

The aim of this study was to evaluate the CROPGRO-Dry bean model for simulating dry bean yield. The model’s genetic coefficients were calibrated based on the cultivars ‘Pérola’, ‘Ouro Negro’ and ‘Ouro Vermelho’ in Viçosa, State of Minas Gerais, Brazil. The coefficients were adjusted based on two experiments that were performed in 2003 with irrigated and nonirrigated water regimes. An additional experiment with irrigation was conducted in 2004. After calibration, the model simulated the bean yield for the period from 1975 through 2006. The simulations were based on daily data on maximum and minimum air temperatures, total precipitation and global solar radiation. The physical and hydric characteristics of the soil and crop management practices were also included. The results show that the crop model can correctly reproduce the observed yield. This finding may indicate that the model is a useful tool to evaluate the crop response to variability and changing climate.
