RESUMO:

Using desiccants on sesame crops can bring the harvest forward and reduce the time the seeds remain in the field after reaching physiological maturity. However, there is little research on this subject in the literature. Therefore, this study aimed to examine pre-harvest desiccants' influence on sesame seeds' physiological quality during storage. Sesame seeds of the K3 cultivar were used, harvest 2024/2024, and produced at the experimental unit of the Center for Seed Studies and Analysis (CEAS), from experimental plots that received desiccation with the following active ingredients: Diquate, Glyphosate, Flumioxazin, and Glufosinate ammonium at the dosages recommended by the manufacturer: 2 L/ha for 200 L of syrup, 1 kg/ha for 200 L, 100 ml/ha for 200 L of syrup and 3 L/ha for 200 L of syrup, respectively, applied 60 days after anthesis (90 days after sowing), in addition to the control treatment. The quality analyses were carried out in the laboratory under a completely randomized design with four replicates. The following tests were carried out: Purity analysis, water content, thousand-seed weight, germination test, seedbed emergence test, accelerated aging test, tetrazolium test, and seedling dry mass test, which were carried out over the storage periods of 0, 30, 60 and 90 days. The partial data obtained was subjected to ANOVA tests. Subsequently, analyses of variance were carried out following the DIC model in a factorial scheme (Factor A x B), followed by the Skott-Knott mean comparison test in the SISVAR program.
