BROCH, Dirceu Luiz et al. Soybean grain yield in cerrado region influenced by sulphur sources. Rev. Ciênc. Agron. [online]. 2011, vol.42, n.3, pp.791-796. ISSN 1806-6690.

Sulphur is a component of protein and aminoacids in plants, being required in an expressive amount by leguminous, as function of high protein levels in these plants. Then, this work aimed to verify the influence of different sulphur sources on soybean grain yield. The experiment was carried out at the experimental area of Fundação MS, Maracajú, MS, in three consecutive years in a randomized block design with four replications, submitted to variance analysis of group experiments. The cultivars used were BRS-133 (2002/03 and 2003/04) and CD 202 (2004/05). As treatments, it was evaluated the application of sulfur as Simple Superphosphate, MAP sulphured + Sulfurgran, Sulfurgran, elemental sulphur, granulated gypsum, Fosmag 509M6, agricultural gypsum throwed on surface, and a witness without application. Soybean crop answer is positive to soil applied sulphur in Brazilian cerrado soils, in most of the time to obtain higher grain yield. Most of S sources were efficient to provide this nutrient for soybean, highlighting the applications of MAP Sulphured + Sulfurgran, Formag 509M6 and agricultural gypsum, that promoted the highest soybean grain yield. Elemental sulphur was not efficient to provide available S for the crop.
