Body

The response of three bahiagrass (Paspalum notatum) cultivars (Pensacola, Tifton 9, and RRPS Cycle 14) to simulated grazing, at two intensities and three frequencies, and continuous cattle grazing were measured by Gates et al. in this study. Forage yield was greater for Tifton 9 and RRPS Cycle 14 than Pensacola, indicating that pastures seeded with these cultivars may be able to support more animals than Pensacola seeded pastures. Yields for all cultivars tended to be greater at the lower clipping height and greater as the interval between clippings increased from 2-8 weeks, however, clipping frequency and intensity did not affect establishment, persistence, root mass, or growth of any cultivar. In the grazing trial, RRPS Cycle 14 tending to decrease under continuous grazing pressure while the other two cultivars were more persistent, this indicates that careful grazing management would need to be used when grazing in pastures seeded with RRPS Cycle 14 and continuous grazing could be used with Tifton 9 and Pensacola.
