Resumo

The objective of this study was to evaluate the effect of organic and inorganic fertilization on nutritive value of Brachiaria humidicola during three climatic seasons at the 21, 28 and 35 days old of growth. The study was carried out on grassland in acid soil. The main effects were climatic season (E), dry, rainfall and winter; kind of fertilizer (TF), without fertilizer, inorganic fertilizer (150-60-00 NPK) and organic fertilizer (15-4,8-8.4 NPK); age of harvest (21, 28 y 35 days) and their interactions. Three replicate were used by treatment. The response variables were crude protein (PD), digestibility in situ of the dry matter (DIMS), neutral detergent fiber (FDN) and digestibility of the FDN (DFDN). The main effects studied and their interactions affected (p
