The objective was to evaluate the accumulation of forage yield, composition and morphology of Tanzania grass pastures (Panicum maximum Jacq. cv. Tanzania-1) fertilized with nitrogen or intercropped with Campo Grande Stylosanthes. Were used a randomized blocks with split plots with three replications and having treatments as main plots: Stylosanthes + Tanzania; Tanzania + 75 kg N ha-1; Tanzania + 150 kg N ha-1; Tanzania + 225 kg N ha-1 and the subplots seasons. The highest percentage of green leaf blade were observed in spring and the pastures with 150 and 225 kg N/ha. The percentage of green stem + sheath were higher in summer and autumn, as well as in pastures fertilized with N. The percentage of dead material was higher in autumn and winter. With the application of 225 kg N/ha, pastures had higher daily accumulation of dry matter in relation to other treatments. The circumference of the stools was similar between the consortium and pastures fertilized with N. The number of live tillers was higher when we used higher doses of nitrogen. Pastures intercropped with stylosanthes or nitrogen fertilized (75 and 150 kg) presents better morphology and daily accumulation of forage.
