Abstract

This study aimed to evaluate the effects of shading on the performance of cultivars of grain sorghum. The test was conducted in a greenhouse using randomized design in a 4 x 2 factorial scheme, corresponding to the four hybrids of grain sorghum (DKB 599, AG 1040, AG 308, BRS 1040) submitted to a condition with and without shade, all treatments with three replications. We evaluated plant height, leaf area, dry matter of leaves, stems, roots, panicles, and the length of the tassel and panicle. The results show that the shaded environment led to greater height of plant sorghum, but lower values of leaf area. The reduction in brightness provided even greater accumulation of dry mass of leaves and stems of all evaluated cultivar. The BRS 308 showed stable production regardless of growth environment.
