RESPOSTA À CALAGEM DA Brachiaria brizantha SUBMETIDA A DIFERENTES DOSES DE ADUBAÇÃO NITROGENADA

Abstract

The bovine production in pastures is characterized in Brazil as a condition of extract exploration, in soils exhausted by other cultures, for the erosion or of low natural fertility, causing low productivities. The work had main objective to evaluate the effects of the acidity corection and nitrogen in Brachiaria brizantha, cv. Xaraés, evaluating the production and the elevation of the tenors of Nitrogen and Calcium in the plant. The experiment was led vegetation home in UNOESTE, in the period of august to november of 2003. 20 seeds were distributed by vase and to the 44 days after the sow the doses of nitrogen and 78 days were applied after the planting took place the cut of the aerial part for determination of the matter it evaporates. The limestone application and nitrogen provided a significant increase in the production of the forage, besides elevating the tenor of Nitrogen and Calcium significantly in the plant. It is like this evident the importance of the manuring in cultures forage for the obtaining of discharges productivities and larger capacity for hectare.
