Summary: Crop model application for upland rice at Centro Oeste region is limited due to lack of daily solar global radiation set data. Therefore, five different solar radiation models proposed by Bristow & Campbell (BC), Hargreaves (HG), Donatelli & Campbell (CD), Donatalli & Bellocchi (DB) and Donatelli et al. (modular mode DCBB) were calibrated with the objective to identify and quantify the errors of simulated Rs on the upland rice yield, biomass and leaf area simulated by crop model ORYZA/APSIM. Based on the results obtained in this study it is possible to conclude that simulated upland rice yield is the most sensitive variable for using estimated global solar radiation. The empirical solar radiation models that showed better performances for crop model using were CD, DB and BC
