Popis:	This trial was carried out to evaluate forage mass in fraction leaf blade (LB), sheath + green stem (SGS), dead material (DE), and crude protein (CP) percentage and neutral detergent fiber (NDF) in the layers of 0 to 7 cm, 7 to 14 cm and over 14 cm high. Coastcross-1 grass and the whole plant of Arachis pintoi (WPA) were evaluated under grazing, from March 2003 to March 2004. The treatments evaluated were CA0 = Coastcross-1 + Arachis without N; CA100 = Coastcross-1 + Arachis with 100 kg of N; CA200 = Coastcross-1 + Arachis with 200 kg of N; and C200 = Coastcross-1 with 200 kg of N, in a random block design, with two repetitions. The proportion of LB and SGS increased, while DE and WPA decreased with the increase of clipping height. No difference was observed among treatments. Arachis had little influence on pasture composition because of its low availability. The highest values (p < 0.05) for CP and the lowest values for NDF were observed in the intermediate and upper layers.
