The purpose of this study was to develop strategies for the recommendation of common bean cultivars testedin VCU trials with regard to the performance of lines with different growth habits, at different fertilizer rates and sowingdensities. It was found that the grain yield of lines is more affected by variations in fertilizer rates than of the sowing density;the response of the lines to higher planting density and fertilizer rate varies with the environment of evaluation and does notdepend on the growth habit, the interactions between fertilizer rates and sowing densities were significant, demonstrating theimportance of VCU trials with different fertilizer rates and sowing densities.
