Época de semeadura da soja e sua relação com a produtividade e qualidade da semente

Abstract

The positioning of a soybean crop is an important factor for its development, so this work seeks to identify the best time for sowing soybean cultivar BMX Zeus IPRO, relating it to seed yield and quality. To obtain the final result, the research was conducted in two parts, firstly, it was conducted in the field, carried out in the 2019/2020 harvest, in the municipality of Nova Laranjeiras, Paraná, with sowing at three different times, 02/10 (E1 ), 10/27 (E2) and 11/24 (E3), after the evaluations of the experiment's yield and harvest components, the second part of the research began, carried out in the seed laboratory of the Federal Technological University of Paraná, campus Pato Branco, where physiological seed quality assessments were performed. Thus, it can be seen that the different sowing times had no significant difference in terms of the physiological quality of the seed and can be marketed for future planting, however for the yield components there were highlights for sowing carried out in E1 and E2, where the best final productivity results can be obtained.
