Influência de diferentes épocas de aplicação de enxofre elementar sobre a produtividade de grãos na cultura da soja

Abstract

Sulfur is a component of proteins and amino acids in plants, which is much needed in legumes, where soybean productivity is defined, and elemental S has the function of increasing the yield of high yields. The objective of this work was to evaluate the yield of soybean in different times of application of elemental S, with application 30 days before sowing on sowing day, 30 days after sowing and control without application in no - tillage system with A randomized complete block design with Red Latosol Dystrophic soil in Chopinzinho - PR. The experimental design was randomized blocks, with twenty repetitions, treatments evaluations, the addition of elemental S had response when applied 30 days before sowing, where it promoted the best grain yield, greater weight of one thousand seeds. Sulfur was effective in increasing soybean yield.
