Abstract/Contents:"Grazing defoliation frequencies (GF) of 2, 4, 6 and 8 wk were applied to established plots of two bahiagrasses ( Paspalum notatum Flugge), three limpograsses ( Hemarthria altissima (Poir) Stapf et. C. E. Hubb) and three bermudagrasses ( Cynodon dactylon (L) Pers) to evaluate grass yield, quality, and persistence at the University of Florida's Agricultural Research and Education Center, Ona. A split plot field arrangement was used with GF as main plots and grass entries as subplots in three randomized complete blocks. Fertilization consisted of 135-50-100 (N-P2O5-K2O) lb acre-1 (151-24-93 N-P-K kg ha-1), yearly. Dry matter (DM) production, forage quality, and crown total nonstructural carbohydrates (TNC) from the initial harvest (December to May accumulated growth) varied significantly among grass entries but were independent of GF. Limpograsses accumulated more DM during the cool period than the other genera. There was a significant interaction between GF and grass entries for DM yield, crude protein (CP) content and in vitro organic matter digestion (IVOMD) during the June to November grazing season. The 2 yr average DM yield from June to November was unaffected by GF for bahiagrasses but increased linearly for limpograsses and curvilinearly for bermudagrasses as GF was delayed. Total annual DM yield was higest for `Floralta' limpograss averaging 7.5 tons acre-1 (16.8 Mg ha-1) and lowest for `Tifton-78' bermudagrass and Hemarthria `PI 364869' averaging 3.9 and 3.7 tons acre-1 (8.7 and 8.3 Mg ha-1), respectively. Limpograsses had superior (58 to 52%; 580 to 520 g kg-1) IVOMD but lowest (11.2 to 5.5%; 112 to 55 g kg-1) CP content at all GF. Bermudagrass exhibited lower (50%; 500 g kg-1) IVOMD when GF was delayed beyond 4 wk. Total non-structural carbohydrates concentration was highest in the bahiagrasses (11%; 110 g kg-1) and lowest in limpograsses (4.6%, 46 g kg-1) and was not affected by GF. Callie 35-3 bermudagrass, Floralta limpograss and bahiagrass were most persistent and encountered 3, 13, and 23% common bermudagrass ground cover after 2-yr grazing. These data suggest that Callie 35-3 maybe be a good addition to the standard pasture grasses but should be subjected to futher gazing evaluation."
