Abstract
Soybeans are a major crop in Brazilian agribusiness, with cultivar selection, location, and sowing date significantly impacting seed yield and quality. This study aimed to evaluate the yield and quality of soybean seeds under different growing environments, combining sowing time and location in tropical floodplain conditions in Tocantins in 2022. Four field experiments were conducted in two locations, with sowing dates of May 17 and May 31 in Lagoa da Confusão, TO. The cultivars Bônus, Extrema, Domínio, SYN1687, and SYN2282 were assessed. Each experiment followed a randomized block design with five treatments and four replications. After full maturity, the crops were harvested and evaluated for yield parameters and seed physiological quality. The cultivars Bônus, Domínio, and SYN1687 produced the highest yields, unaffected by sowing dates. However, the growing environment influenced seed vigor and viability, with the May 31 sowing favoring seed quality.
