Morfogênese do capim-marandu em área degradada submetido a estratégias de manejo e adubação nitrogenada

Sustainable exploitation of forage requires an adequate supply of nutrients, in adequate amounts for good plant development. In this sense among the most nutrients required by plants, nitrogen stands, once your supply by mineralization of organic matter is not sufficient to supply the needs of the plant, as a result achieve greater levels of productivity and quality of pasture. The aim of this study was to evaluate the morphological development of Marandu grass degraded land through management strategies, using as nutrient source N. The experiment was conducted in a randomized block design (DBC), a 2x4 factorial arrangement with the factors evaluated: two sward heights (25 and 35cm) and four nitrogen rates (50,100, 150 and 200 kg ha-1). The doses of N treatments and cutting height had significant effects separately for the parameters (TAlF, NFV and Filocromo). The cutting height of 35 cm was the one that obtained the highest number of green leaves (NFV), since the height of 25 cm gave higher values ​​of leaf elongation rate. The dose of 100 kg ha-1 gave the maximum value of filocrono (18,75 days / sheet).
