The studied species were: millet, forage sorghum, finger-millet, gray andblack mucuna, sunn hemp, lablab and forage turnip. The assay was installed in two steps, May 12, 2002 (draughtseason) and December 3, 2002 (rain season). All the phabaceae, besides forage sorghum and millet, producedabout twice more phytomass per area during the rain season compared to the draught season. The millet wassuperior to the other species during the rain season, reaching 16.7 t ha-1 of dry phytomass, being the sunn hempthe phabaceae with the biggest production (12.1 t ha-1). The forage turnip isn't indicated for the dry phytomassproduction for soil covering in the seasons studied. During rain season all others respond to the minimumnecessary production of dry phytomass for soil covering and during the draught season, just the millet does it.Aiming animal feeding, all the species studied can be used, with restrictions to sunn hemp, which may have toxicsubstances, independent of sowing season. The millet is the favorite culture once it presents adequate dryphytomass production in both evaluated seasons, associated to nutritional quality of the produced forage crop,besides possibility of re-sprouting after the cut or grazing.Este trabalho foi realizado no munic¨ªpio de Fernand¨®polis/SP com o objetivo de avaliar opotencial de produ o e a composi o bromatol¨®gica da fitomassa seca de oito esp¨¦cies vegetais e em duas¨¦pocas de semeadura para cobertura de solo e/ou alimenta o animal. As esp¨¦cies estudadas foram: milheto,sorgo forrageiro, capim p¨¦-de-galinha, mucuna cinza e preta, crotal¨¢ria, lablabe e nabo forrageiro. O ensaio foiinstalado em duas etapas, 12/05/2002 (¨¦poca da seca) e 03/12/2002 (¨¦poca das ¨¢guas). Todas as fab¨¢ceas, al¨¦mdo milheto e do sorgo-forrageiro, produziram cerca de duas vezes mais fitomassa por ¨¢rea na ¨¦poca das ¨¢guas emrela o ¨¤ da seca. O milheto foi superior ¨¤s demais esp¨¦cies nas ¨¢guas, atingindo 16,7 t ha-1 de fitomassa seca,sendo a crotal¨¢ria, a fab¨¢cea com maior produ o (12,1 t ha-1). Concluiu-se que o nabo forrageiro n o ¨¦ indicadopara a produ o de fitomassa seca para cobertura do solo nas duas ¨¦pocas estudadas, sendo que, nas ¨¢guas, todasas demais atendem ¨¤ produ o m¨ªnima de fitomassa necess¨¢ria para uma adequada cobertura do solo, e na seca,apenas o milheto.
