Description
Nine white clover (Trifolium repens L.) cultivars, among them 2 bred in Rio Grande do Sul, were evaluated in association with annuai ryegrass and pensacola bahiagrass. In a plot experiment, during 4 years, 17 harvests were cut to determine lhe dry matter (DM) yield of the mixture components. The annual ryegrass produced in· the first year 1634 kg/ha OM and in the second year, by natural reseeding, only 120 kg/ha. The pensacola bahiagrass increased DM yield from 954 kg/ha in the second year to 4588 kg/ha in the fourth year without any nitrogen (N) fertilisation. The while clover cultivars produced an average DM yield, in the first year, of 1900 kg/ha and !hen stabilised around 600 kg/ha. Tho new cultivars Gualba S I and Jacul S2 in the first, third and fourth years were among the best performing cultivars. In the second year cv. Haifa was the highest in DM yield.
