ABSTRACT
Our study aimed to investigate the role of supplementation with sulfur (S) on soybean tolerance to water stress, analyzing aspects related to plant growth, relative tolerance and sulfur accumulation in plants tissues. The experimental design was in randomized blocks (DBC), in a 3 × 2 × 2 factorial arrangement, consisting of three levels of drought stress (60% field capacity (FC) - control treatment; 45% FC - moderated drought; and 30% FC - severe drought), two doses of sulfur (S) (40 and 80 kg ha-1,) and two soybean genotypes (BÔNUS 8579 and M8808), with four replications. In this case, the following parameters were analyzed: fresh and dry mass; relative tolerance to water stress; and sulfur content in plant tissues. Supplementation with S at 80 kg ha-1 emerges as a promising strategy for growing soybean plants of the M8808 genotype in soils with low water availability, being a viable alternative to mitigate the deleterious effects of water deficit.
