Comportamento de cultivares em terras baixas no sul do Rio Grande do Sul e efeitos da adubação com enxofre sobre parâmetros de produção e de qualidade de grãos de soja

Abstract

Soy is a plant of the Fabaceae family, rich in proteins, lipids, B-complex vitamins and minerals. It has numerous uses, such as human consumption, animal consumption and industrial applications. The objective of this work was to compare the production yield and quality properties of the soybean cultivars BRS 216, BRS 232, BRS 257, BRS 525, BMX Delta IPRO e Tec IRGA and to test the effects of elemental sulfur application time on these soybean yield and quality variables. The field experiment was conducted at Centro Agropecuário da Palma and laboratory analyzes were carried out at the Post-harvest, Industrialization and Grain Quality Laboratory (LABGRÃOS) of the Faculty of Agronomy “Eliseu Maciel” at the Federal University of Pelotas, in the municipality of Capão de Leão, in the southern region of Rio Grande do Sul. The genotypes showed full development, providing good cultivation potential for the region. The proximate composition parameters were consistent with literature data. The results of the application of sulfur indicate good prospects, however, further studies are need ed in different crop years to test doses and timing of application. The colorimetric profiles did not show to be affected by the tested production managements. Due to operational restrictions resulting from sanitary measures, it was not possible to complete the amino acid analysis and carotenoid evaluation, requiring changes in the analytical methodology.
