Accumulation of Dry Matter and Morphological Composition of Irrigated Mombaça Grass Fertilized with and without Nitrogen under Grazing

Brazil is the holder of the largest commercial cattle herd in the world and the world\u27s leading exporter of fresh and industrialized meat. Beef production is based on pastures and the production system is influenced by absence of fertilization and the seasonality of forage during of this the year, caused mainly by temperature, rainfall and luminosity. Nitrogen (N) is the most important element for the development and growth of grasses, since it accelerates the formation and growth of new leaves, improves regrowth vigor resulting in greater production and carrying capacity of pastures (Cecato et al. 2011). The present study aimed to evaluate the accumulation of dry matter and percentage of leaf blade of irrigated Mombaça grass (Panicum maximum Jacq. cv. Mombaça) with four N fertilizer doses, under intermittent grazing
