- Abstract
Brazil has a large cattle herd, and pastures have offered the most practical and economical way of providing them forage. This work was carried out at the UniversidadeEstadual de Maringá, in CidadeGaúcha city, Paraná state, and it aimed to evaluate the effect of plant density and nitrogen levels on forage production of Brachiariabrizantha cv. Piatã.The experiment was set out in a randomized complete block design in a 4x4x10 factorial scheme, with three replications. The evaluated factors were: i) nitrogen doses (0, 17, 33 e 50 kg ha- 1 cut-1), applied on the soil surface after each cutting cycle; ii) plant density (10, 20, 30 e 40 plants m-2) and; iii) 10 pasture cutting cycles which were performed over the experiment. Fresh and dry matter productions of the pasture aerial part were evaluated. The factors cutting cycles and nitrogen levels had influenced on fresh and dry matter production of pasture. The highest yields of fresh and dry matter production were obtained at a plant density of 10 plants m-2 and the smallest yields for the plant density of 40 plants m-2. Increasing the nitrogen dose by 50 kg N ha-1 cut-1 provided an increase in the fresh and dry matter production of Brachiariabrizantha cv. Piatã.
