Qualidade fisiológica de sementes de soja produzidas na entressafra em Chapada do Pareceris - MT

Abstract

The aim of this study was evaluated the quality physiologic of soybean seeds produced in an off-season period. The experimental unit consisted of one share of 0.75 m wide x 1.0 m in length and spacing of 0.15 m with a density of 100 seeds.m-1, four lines totaling 400 sowing seeds per lot, with a total area of 0.75 m2. The cultivars were P98Y11RR and CD 242 RR. The seeds were evaluated by means of the germination and vigor (first count, seedling vigor classification and accelerated aging) tests. The results showed that soybean production resulting from the period of off-season can present high physiological quality. The seeds of soybean cultivar CD 242 RR potentially provide high field emergence, regardless of whether or not treatment with fungicide. Seed treatment of soybean cultivar P RR 98Y11, fungicide, favors the emergence in the field.
