About the project: The ruminant production chain in northern Brazil is based on forage, and its management and fertilization ensure the perennial nature of grasses, which are of fundamental importance for meat and milk production. When climate and management conditions are adequate, grasses of the genus Panicum present high production per area, good nutritional value, high acceptability by animals, without presenting toxic or antinutritional principles, because in Af climate conditions, being a condition characterized by frequent rainfall in all months of the year, that is, absence of seasonality in the rainfall regime, there is no seasonality in forage production as defined as in other places in Brazil. Even so, studies involving the growth dynamics of forages and nitrogen fertilization in the North region are incipient. We therefore aimed to evaluate the characteristics of Panicum maximum cv. Mombaça fertilized with increasing doses of nitrogen in Af climate conditions, evaluating productive, morphogenic, structural and chemical characteristics of Mombaça grass in order to define the intensive exploitation of this forage resource in a sustainable way, minimizing soil degradation and GHG emissions.
