Effects of grazing management and N fertilization on the persistence of vaseygrass (Paspalum urvillei), a weedy species in limpograss (Hemarthria altissima) pastures were examined at the Beef Research Unit at the University of Florida Gainesville (29° 38’ N; 82° 22’ W). Six treatments combinations of grazing regimes (continuous or rotational), stubble height (15 cm or 30 cm) and fertilizer application rates (50 or 150 kg N ha?¹) were applied to 16 plots in a split-plot design. Treatment effects were measured on Vaseygrass grass density and percent cover of Vaseygrass, limpograss and other plants before treatments were imposed and following the final grazing period of the second year.
