The research was carried out to verify the influence of the nitrogen input in an Italian ryegrass (Lolium multiflorium L.) and oat (Avena strigosa Scherb) pasture, in presence and absence of white clover (Trifolium repens L.), checked by the dry matter accumulation, dry matter yield, average daily gain, liveweight gain and stocking rate a crop-pasture rotation system, on no tillage system. Soybean (Glycine Max L.) was cultivated before the grass. The experimental design was complete randomized blocks with split-plot model and three replications. In the plots, four nitrogen levels were tested (0, 100, 200 and 300 kg.ha-1) and in the split-plot model, the presence and absence of white clover. Increasing nitrogen levels increased in a cresecent linear way the dry matter accumulation and dry matter yield. The stocking rate and liveweight gain per hectare of bovine increased, as the nitrogen levels increased. The results showed the effect of nitrogen input on the daily accumulation rate, dry matter yield, stocking rate and liveweight gain.
