PENGARUH PEMUPUKAN NITROGEN DAN TINGKAT NAUNGAN TERHADAP KANDUNGAN BAHAN KERING, SERAT KASAR DAN ABU RUMPUT Brachiaria humidicola

Abstract

THE EFFECTS OF NITROGEN FERTILIZER AND SHADING LEVELS ON DRY MATTER, CRUDE FIBER AND ASH CONTENT OF Brachiaria humidicola. The aim of this experiment was to determine the effects of fertilizer different level of shading and nitrogen on the crude fiber, dry matter and ash content. The treatments 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 of three levels of shading : N₁ = 0%, N₂ = 40%, and N₃ = 70%. Treatments whe arranged in factorial based on randomized block design (RBD). Data were analysis using Minitab Version 11, and followed by Tukey Simulteneous Test. The highest crude fiber content was in N₁P₄ coupared to other interactions. The result showed that the effect of Nitrogen fertilizer and shading were no significant on dry matter, ash and crude fiber content of B. humidicola however, the interaction of the two factor were significant only on crude fiber content. It can be concluded that the best condition was on 0% without with 150 kg Nitrogen fertilizer /Ha.
