This experiment was performed aiming to evaluate tiller population density, forage mass and its morphological components on pastures of Brachiaria decumbens cv. Basilisk. during deferment. The treatments encompassed four deferred grazing periods (18, 46, 74 121 days). A randomized block design with two replications used. numbers vegetative tillers (VT), reproductive (RT) dead (DT) in the pasture were determined. masses green leaf blade (GLBM), stem (DSM) (DFM) also There a reduction number VT (from 1,491 944 m-2) deferment period. RT DT not influenced by periods. Their averages 211 456 m-2, respectively. Longer deferring resulted an increase GSM 2,965 4,877 kg ha-1 dry mass) DFM 2,324 4,823 mass), but it did influence GLBM (average 2,047 mass). In Viçosa, Minas Gerais State, Brazil, Basilisk fertilized beginning March must be kept for about 70 days order conciliate both quality quantity production.
