The objective of this experiment was to evaluate the effects of irrigations, clipping of forage and nitrogen (N) levels (0, 50, 100 and 150 kg ha-1) on Brachiaria decumbens Stapf cv. Basilisk at forage yield, and components of harvested seed yield. The experimental design was arranged in a randomized split-split-plot design with four replications. The N (Urea) doses were applied on November 10 2007. It is evaluated the dry matter (DM) of forage, culms, of leaf lamina, of dead matter, inflorescence density, and the number of seed by inflorescence. There was no influence of irrigation at forage yield. Forage yield and leaf lamina yield was affect by N levels. Clipping effect was verified at reproductive tiller density and number of seed/inflorescense. The N levels affected seeds/inflorescense at the flowering of December and April.
