Summary: A greenhouse experiment was conducted to verify the need of Rhizobium inoculation to improve nodulation, N2 fixation and plant dry weight of 9 tropical legumes for green manuring in a phosphorus deficient Red-Yellow Podzolic soil serie Itaguaí of Rio de Janeiro State, Brazil. The following legumes species were used: Mucuna aterrima, Mucuna deeringiana, Mucuna nivea, Canavalia ensiformes, Canavalia brasiliensis, Cajanus cajan, Lablab purpureus, Crotalariajuncea and Crotalaria anagyroides. The treatments with and without inoculation did not show statistical difference for nodule number but for nodule dry weight the autochthonous strains provided higher values for C. ensiformes, M.aterrima and the weight average of all legumes. Aerial plant part dry weight and total N of aerial part showed no statistical difference for these two treatments. The application of mineral N fertilizer decreased number and dry weight of nodules and increased the aerial plant part dry weight and total N. This is an indication that maximum potential of production of those plants were not reached only with N2 fixation, demonstrating the need for the selection of more efficient Rhizobium strains for these plant species. For all parameters analised C. ensiformes showed higher values.

As espécies utilizadas foram: mucuna-preta (Mucuna aterrima), mucuna-rajada (Mucuna deeringiana), mucuna jaspeada (Mucuna nivea), feijão-de-porco (Canavalia ensiformes), feijão-bravo-do-Ceará (Canavalia brasiliensis), guandu (Cajanuscajan), lablab (Lablab purpureus), Crotalaria juncea e Crotalaria anagyroides. Os tratamentos com as estirpes introduzidas pelo inoculante e com as estirpes autóctones do solo não apresentaram diferenças significativas quanto ao número de nódulos produzidos, porém as estirpes autóctones produziram significativamente maior peso de nódulos para o feijão-de-porco, mucuna-preta e no somatório de todas as leguminosas. O peso da parte aérea seca e o N-total também não foram diferentes nos dois tratamentos sem N mineral. A aplicação de N-mineral ao solo diminuiu o número e peso de nódulos, mas aumentou o peso da parte aérea e o N-total da parte aérea, indicando que o potencial máximo de produção para essas espécies ainda não foi atingido só com a fixação simbiótica, sendo importante a obtenção de estirpes mais eficientes. Em todos os parâmetros analisados, o feijão-de-porco obteve os maiores valores. Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraChada, Sylvia de Souzade Polli, Helvécio2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14065Pesquisa Agropecuaria Brasileira; v.23, n.11, nov. 1988; 1197-1202Pesquisa Agropecuária Brasileira; v.23, n.11, nov. 1988; 1197-12021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14065/8047info:eu-repo/semantics/openAccess2014-09-18T18:38:05Zoai:ojs.seer.sct.embrapa.br:article/14065Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-18T18:38:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
