Conteúdo:	An understanding of the effects of frequency and severi- ty of defoliation on the sward structure of pastures is essential for identifying pasture management strategies that are more efficient in forage usage in tropical envi- ronments (Da Silva and Nascimento Jr 2007; Euclides et al. 2010). Some pasture species have not yet been inves- tigated in this way, e.g. cultivars of Cynodon. The poten- tial of this grass in tropical environments suggests that it should be given priority (Pedreira 2010). This study was designed to evaluate the effects of 2 frequencies (90 and 95% light interception) and severities (20 and 30 cm residue) of defoliation on the structural characteristics of Puerto Rico stargrass pasture (Cynodon nlemfuensis) during 3 seasons (fall, winter and spring).
