ABSTRACT A better understanding of the differential growth of common bean cultivars with increasing soil sulfur (S) availability can indicate how to improve common bean grain yield in soils of Savannas. The objective of this study was to evaluate the response of sprinkler-irrigated common bean cultivars to sulfur fertilization in a no-tillage system. The experiment was designed as a randomized block in a split-plot scheme with sulfur rates (0, 10, 20, 40, and 60 kg ha-1) as main plots and common bean cultivars (BRS Requinte, BRS Cometa, Diamante Negro, BRS Grafite, BRS Valente, and Corrente) as subplots, with three replications. Common bean cultivars did not differ regarding grain yield response to sulfur rates, which fitted to a quadratic equation. Among the cultivars tested, only BRS Requinte and BRS Valente differed in grain yield for S fertilization, the first being more productive. Moreover, S fertilization allows significant increases in common bean grain yield in average of six cultivars and must be considered in cropping systems aiming for high yields.
