Produtividade e qualidade do trigo mourisco sob diferentes dosagens de adubação e regimes hídricos

Abstract

Considering the scarcity of information in the South region and the potential use of buckwheat (Fagopyrum esculentum Moench) as pasture, silage and grain use, the objective of this work was to evaluate the nutritional quality and grain yield at different NPK doses, cultivated with and without the use of irrigation. The experiment was carried out in the period between harvest, with randomized blocks design (RBD), containing three treatments plus the control. Being evaluated before the period of physiological maturation, the plant height, stem diameter, root length and number of bunches. After reaching the point of maturation, 95 days, the grains were harvested manually. The productivity of the plots (kg/ha), dry matter (DM), mineral matter (MM), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP), Lignin. The results obtained in the development of the culture in the field were greater in the treatments that had higher fertilization. The non-irrigated treatments presented higher productivity. Regarding the nutritional quality of the grains, there was better results for dry matter, crude fiber, and crude protein in the irrigated treatments.
