Nitrogen and Phosphate Fertilization Maximize Grass BRS Zuri Performance

Abstract

The low nutrients levels available in pasture formation reduces the forage yield. Soil correction and fertilization practices are considered priorities in the planning, renovation or recovery of pastures. The aimed of this experiment was to evaluate the effect of nitrogen and phosphate fertilization rate in productivity of the Panicum maximum cv. BRS Zuri. The experimental design was a randomized block design in a 3×4 factorial arrangement, with three doses of superphosphate (0.0, 80.0 and 160.0 kg.ha^-1) and four doses of ammonium nitrate (0.0; 20.0; 40.0 and 60.0 kg.ha^-1), with three replicates. The following parameters were evaluated at 120 days after implantation: green mass and dry matter yield, plant height, number of plants and tillers per square meter. The doses of 80.0 and 160.0 kg.ha^-1 of P₂O₅ and 60.0 kg.ha^-1 of nitrogen combined to each other showed the best results for forage yield.
