Abstract


Nitrogen fertilization is an essential practice for the increase in biomass of forage, reducing the seasonality of production throughout the year. Thus, the objective was to evaluate the green and dry matter accumulation of more sheaths leaf blades and stems of Brachiaria cultivars in the dry season. The experiment was conducted from May to October 2014, at the State University of Mato Grosso, Brazil, in an area of 1.500 m2. The experimental design was a randomized block design with three replications. The treatments were characterized by factorial 2 x 2 x 5, two forage (cv. Marandu and Mulato II), two N sources (urea and ammonium sulphate) and five doses of N (0, 50, 100, 150 and 200 kg ha-1). Nitrogen fertilization affected the productive characteristics of forages, with greater accumulation of biomass at a dose of 200 ha-1 kg N. The nitrogen sources and forage influenced to a greater magnitude green mass production and dry stalks.
