Sulfur modulates yield and storage proteins in soybean grains

This study evaluated the nutritional quality, yield, and storage protein modulation in soybean grains response to levels sources of sulfur (S) a dystrophic Ultisol. We used five S (0, 50, 100, 150 200 mg kg –1 ) four (elemental pastille - ESPA, gypsum GY, gypsite GI elemental powder ESPO). Plants treated with 50 GI, ESPO ESPA had largest grain yield values. Low supply resulted lower yields for all tested. Sulfur deficiencies were observed at resulting concentrations globulin higher concentration glutelin albumin grains, possibly because content leaf was below range adequate soybean, leading In general, application (GY, ESPO) increased fractions. The results show that proper is essential optimize increase proteins grains. granulometry fertilizers key factor availability plants. presents relevant information on fertilization soybeans, which could provide better quality benefits animal health.
