Depth of sulfur fertilization as affecting nodulation and grain yield of common bean.

Depth of sulfur (S) fertilization can affect common bean (Phaseolus vulgaris L.) development and a better understanding of its interaction with plant nodulation could help to improve common bean grain yield in soils under Cerrado. The objective of this study was to determine nodulation, grain yield and yield components of common bean as affected by rates and deep of S fertilization. The experimental designed was a randomized block in a factorial arrangement 4 x 2, with four replications. Treatments were the combination of sulfur rates (0, 20, 40, and 60 kg ha-1) at two depths (0.06 and 0.12 m) in two growing season (2014 and 2015). S fertilization depth did not affect number of nodules, root and shoot dry matter of common bean. The application of S in the uppermost layer provided significant increases in the number of pods per plant, number of seeds per pod and grain yield of common bean. Fertilization with S provided significant increases in grain yield of common bean. Thus, the sulfated fertilization should be considered in farming systems aiming for high yields.
