英文摘要	This study evaluated the competitiveness and productivity of four non-native grass species from Africa introduced in the Brazilian semi-arid region. The experiment had a randomized block design with four replications. The grasses evaluated were Cenchrus ciliaris L., Digitaria pentzii Stent, Urochloa mosambicensis Hackel Dandy, and Megathyrsus max-imus (Jacq.) B. K. Simon & S. W. L. Jacobs. Megathyrsus max-imus and Urochloa mosambicensis showed the best combination of greater forage mass per harvesting (1818 and 1141 kg dry matter (DM) ha-1 per 35-day, respectively) and lesser herbage accumulation of weeds (453 and 156 kg DM ha-1 per 35-day, respectively). Despite the differences in suppressing the weed mass between different non-native grass species, all grasses showed a considerable level of similarity between their floristic composition (family-level 70%, specieslevel 60%). All pastures were characterized by a higher number of herb weeds than shrubs and trees, however, there was more mass accumulation from shrubs. The tallest grass in the study (Megathyrsus max-imus), and the one with the best dispersing capacity (Urochloa mosambicensis), showed advantages in outcompeting the native weeds and accumulate forage mass. The intense incidence of broad-leaf shrub species must be taken as a signal of the initial stages of pasture degradation and ecological succession.
