This work had theobjective to evaluate phenological and productive aspects of native (Adesmialatifolia, A. tristis) and exotics legumes (Lotus corniculatus,L. uliginosus, Trifolium repens) as for the phenological stageon first-cutting: vegetative (CEV) and flowering (CEF). The plants were establishedas monoculture in the field and evaluated between May/2000 and September/2001,in Passo Fundo, Rio Grande do Sul. After the first cutting the plants were defoliatedin 45 days intervals. There were nine cuttings in CEV-management and seven inthe CEF-management. The phenological stage on first-cutting modified significantly(P<0,05) the dry matter (DM) production of T. repens (CEV = 9.000kg/ha of DM, CEF = 7.000 kg/ha of DM) and A. tristis (CEV = 4.000 kg/haof DM, CEF = 8.000 kg/ha of DM). L. corniculatus produced about 15.000kg/ha of DM and A. latifolia, 2.000 to 3.000 kg/ha of DM, regardlessthe management. L. uliginosus did not flowered, producing 7.000 kg/haof DM in the CEV-management. The native legumes showed poor persistence withdeath of the plants (A. tristis) and stolons (A. latifolia) atthe end of the growing season. The highest production of the T. repenswas in the spring and for the Lotus species, in the summer.
