Productive traits and nutritional value of Urochloa ruziziensis submitted to different planting densities and defoliation intensities

ABSTRACT The aim of this study was to evaluate the forage mass and accumulation nutritional value cultivars Kennedy BRS Integra (Urochloa ruziziensis), subjected two planting densities (15 30 plants/m2) three stubble height (15, 40 cm). experimental design a randomized block, in 2x2x3 factorial, with replications. period comprised agrostological years. Plants managed under lower (15cm), showed leaf:stem ratio higher canopy heights at harvest, based on light interception 95%. highest observed cultivar density plants/m2). high nutritive value, without influence studied factors. In general, were similar for most variables studied. Planting 15 plants/m2 moderate defoliation (30cm residue) resulted accumulation, especially second year after planting. These targets are suggested management U. ruziziensis cultivars.
