Resumo: The crops of cowpea (Vigna unguiculata), crotalaria (Crotalaria juncea and Crotalaria paulina), pigeon pea (Cajanus cajan), feijão-bravo-do-ceará (Canavalia brasiliensis), jackbean (Canavalia ensiformis), lab-lab (Dolichos lab lab), and mucuna-preta (Stizolobium aterrimum) were evaluated as green manure and cover crops in an Ultisol soil in Viçosa, MG, Brazil. The rate of crop establishment and percent of soil coverage were evaluated. Fresh and dry biomass, root density and nutrient content were determined at flowering stage for each species. Jackbean was the best species for both rate of crop establishment and percent of ground coverage. Pigeonpea was the best in terms of root penetration in the soil, biomass production and nutrient immobilization. The crotalarias and cowpea were the most sensitive to soil compaction, having their root mass concentrated at the soil surface.

Foram avaliadas a velocidade e a percentagem de cobertura do solo proporcionadas pelas espécies. No florescimento de cada espécie, determinou-se o peso verde e seco da biomassa aérea, o teor de nutrientes e a densidade radicular dos adubos verdes. Para a conservação do solo, destacou-se o feijão-de-porco quanto à velocidade inicial e percentagem de cobertura do solo. O guandu foi a espécie com maior potencial para penetração de raízes no solo, produção de biomassa aérea e imobilização de nutrientes. As crotalárias e o caupi mostraram-se as espécies mais sensíveis à compactação do solo, concentrando suas raízes mais à superfície.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlvarenga, Ramon Costada Costa, Liovando MarcianoFilho, Waldemar MouraRegazzi, Adair José1995-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4290Pesquisa Agropecuaria Brasileira; v.30, n.2, fev. 1995; 175-185Pesquisa Agropecuária Brasileira; v.30, n.2, fev. 1995; 175-1851678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4290/1576info:eu-repo/semantics/openAccess2010-05-31T20:08:04Zoai:ojs.seer.sct.embrapa.br:article/4290Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-05-31T20:08:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
