Pesquisa do Estado de Minas Gerais (FAPEMIG)Empresa de Pesquisa Agropecu?ria de Minas Gerais (EPAMIG)Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq)Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES)Objetivou-se com este trabalho avaliar o efeito de diferentes coberturas de plantas sobre a qualidade fisiol?gica de sementes de feij?o em plantio direto no munic?pio de Diamantina - MG. O experimento foi instalado no Campus II da UFVJM, num Neossolo Quartzar?nico ?rtico t?pico, no delineamento em blocos casualizados, com dez tratamentos e quatro repeti??es. Os tratamentos constitu?ram-se de palhada dessecada e ro?ada de 1) Brachiaria decumbens cv. Basilisk, 2) Brachiaria brizantha cv. Marandu, 3) Panicum maximum cv. Tanz?nia, 4) Panicum maximum cv. Momba?a, 5) Mucuna aterrina (mucuna preta), 6) Calopogonio muconoides cv. Calopogonio, 7) Dolichos lab lab (lab lab), 8) Cajanus cajan (guandu), 9) Cobertura natural e 10) Plantio convencional onde se efetuou o plantio de feij?o cultivar Talism?. A qualidade fisiol?gica das sementes foi avaliada pelos testes de germina??o (primeira contagem e contagem final); condutividade el?trica dos solutos; peso de 100 sementes; comprimento e peso das pl?ntulas; ?ndice de velocidade de germina??o e teor de ?gua das sementes de feij?o. As gram?neas Panicum. maximum cv. Momba?a, Brachiaria brizantha cv. Marandu, B. decumbens cv. Basilisk e P. maximum cv. Tanz?nia produziram mat?ria seca em quantidade e uniformidade para maior conserva??o de ?gua e prote??o do solo para viabilizar o sistema plantio direto. A qualidade das sementes n?o foi afetada pelos manejos de solo utilizados e sim pelas condi??es clim?ticas na matura??o.The objective this work was evaluate the effect of different coverings plants on the physiological quality seeds of bean in no-tillage system in Diamantina - MG. The experiment was installed in the Campus II of UFVJM, in a Neossolo Quartzar?nico ?rtico t?pico, in blocks randomized design, with ten treatments and four replicates. The treatments were constituted of control chemical and rubbed straw of 1) Brachiaria decumbens cv. Basilisk, 2) Brachiaria brizantha cv. Marandu, 3) Panicum maximum cv. Tanzania, 4) Panicum maximum cv. Momba?a, 5) Mucuna aterrina (black mucuna), 6) Calopogonio muconoides cv. Calopogonio, 7) Dolichos lab lab (lab lab), 8) Cajanus cajan (guandu), 9) Natural covering and 10) Conventional plantation where the bean plantation was made to cultivate Talisman. The physiological quality of the seeds was evaluated by the germination tests (first and final count); electric conductivity of the solute; weigh of 100 seeds; length and weight of the plants; index of germination speed and text of water of the bean seeds. The grass Panicum. maximum cv. Momba?a, Brachiaria brizantha cv. Marandu, B. decumbens cv. Basilisk and P. maximum cv. Tanzania produced dry matter in amount and uniformity for larger conservation of water and protection of the soil to make possible the no-tillage system. The quality of the seeds was not affected by the used soil handlings but had the influence of the climatic conditions in the maturation
