Qualidade físico-química de sementes de milho tratadas com moringa oleifera lam. durante o armazenamento.

Abstract

Brazil is a country whose great potential for grain production has not yet been fully exploited. Corn is the most widespread and cultivated crop because it adapts to the most different ecosystems. Along with the effort to increase productivity, it is necessary to improve the harvesting process and the grain storage conditions. However, prolonged storage can only be achieved when harvesting, cleaning, drying and insect control practices are adopted correctly. The use of products applied through seeds, especially when stored, is a routine practice for the corn crop; However, growing concern about the environment and safety during the seed handling process has increased the demand for application technologies that allow risk reduction without compromising seed quality.Thus, the objective was to evaluate the physiological quality of maize seeds submitted to treatments, with five replicates, with doses equivalent to zero; 0.5; 1; 2 and 4 grams of the Moringa oleifera Lam. seed powder for each 10 grains of corn, with contact time corresponding to zero, 2, 4, 6 and 24 hours, 30 days and 6 months. The determinations were: germination test, moisture, volumetric weight, weight of 1000 grains, ash, acidity index and fungi. The results obtained show that the physiological quality of the corn seeds with the application of Moringa oleifera Lam. on maize seeds is technically feasible and can be stored for up six months without compromising their physiological quality.
