Abstract

THE EFFECTS OF NITROGEN FERTILIZER AND SHADING LEVELS ON PERFORMANCE AND CRUDE PROTEIN CONTENT OF Brachiaria humidicola. The aim of this experiment was to study the effects of different levels of shading and nitrogen on the performance and nitrogen content of B. Humidicola. The treatment were consisted of four levels of nitrogen in from of urea fertilizer: P1 = 0 kg/Ha, P2 = 50 kg/Ha, P3 = 100 kg/Ha, P4 = 150 kg/Ha, and three levels of shading: N1 = 0%, N2 = 40% dan N3 = 70%. Treatmens   was arranged in infactorial based on ramdomized block design (RBD). Date was analysis by using Minitab Version 11, and followed with Turkey Simultaneous Test, to determined the different among treatments, from analysis of variance. The result showed the higher number of tiller was found at the interaction of P3N1, P4N1, P2N2 and P3N2, with significantly different compared to the other interactions. Furthermore, analysis of varians showed the interaction of the treatments were effected significantly on the content of crude protein (P < 0,05) where the interaction of N1P4 has the crude protein content 9,74% significantly higher (P < 0,05) compared to other interactions. On the other hand the interaction of the treatments was not effected significantly (P < 0,05) on the leaf: steam ratio. Based on the result of this experiment it can be concluded that B. humidicola responsive to nitrogen farilizer up to 100 kg urea/Ha to provide optimal performance and crude protein content under shade of 40%.
