Conteúdo: 	Three is a need for supplementary winter feed for cattle during the December-April cool season because of the poor growth from permanent pasture species. Annual ryegrass (Lolium multiflorum Lam.) and between clover (Trifolium alexandrinum L.) have been used successfully in south Florida during the cool season to provide additional forage during this period. Yield comparisons of these annuals have not been obtained, nort have the effects of different cutting mangements been determined. Therefore, yield comparison of berseem and ryegrass were obtained from four small-plott clipping experiments; and the effect of cutting interval (CI), cutting height (CH), and plant spacing (PS) on yield and development of berseem were determined. Because of the lack of hardseedness in berseem (and therephore the lack of self-regeneration from year to year), a hardseededness study of many berseem accession and seledctions was conducted. All experiments were conducted on prepared seedbeds. Resuslts indicate no major yield response to seedling rates of 11 to 56 kg/ha for berseem, or 11 to 51 kg/ha for ryegrass. Yields generally were higher than those for berseem, and ryegrass receiving 112 kg/ha of N yielded signifiantly more than ryegrass receiving 56 kg/ha. Yields of berseem significantly increase as Ci and CH increased, and with decreasing PS from 50 to 10 cm. Generally, selected berseem clover lines contained more hard seed than a commercial cultivar, although variation from year to year was high among lines.
