Resumo: The objectives of this study were to evaluate the efficiency of pigeonpea (Cajanus cajan) biomass incorporation to the soil as well as the effect of presence or absence of pigeonpea hedgerows on soil fertility and productivity of three vegetables, beet, carrot and dwarf green bean. Samples were randomly taken in a block design with three replications for each crop. In the field, no other fertilization treatment was applied. In plots without biomass incorporation, nitrogen showed negative balance, whereas in the field with biomass incorporation a high positive N-balance was found. Concerning phosphorus, positive balances were determined in plots without biomass incorporation, however, the uptake of P increased significantly after biomass incorporation in all crops used. The results indicate that pigeonpea alley cropping system may represent an advantageous option for organic farmers to maintain or to improve soil fertility.

O delineamento usado foi de blocos casualizados completos em esquema de parcelas subsubdivididas com três repetições. As produtividades de beterraba, cenoura e feijão-de-vagem não foram afetadas pelos tratamentos. Nas parcelas onde não houve incorporação da biomassa de guandu, o balanço de nitrogênio no sistema foi negativo, ao passo que com a incorporação, esse balanço foi positivo. Embora tenha ocorrido balanço positivo para o fósforo nas parcelas sem a incorporação de biomassa de guandu, houve um aumento significativo na absorção desse elemento pelas hortaliças quando o material foi incorporado. O sistema de cultivo em aléias de guandu pode representar uma prática vantajosa para os produtores orgânicos, por contribuir na manutenção da fertilidade do solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlves, Sandra Maria CamposAbboud, Antonio Carlos de SouzaRibeiro, Raul de Lucena DuarteAlmeida, Dejair Lopes de2004-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6884Pesquisa Agropecuaria Brasileira; v.39, n.11, nov. 2004; 1111-1117Pesquisa Agropecuária Brasileira; v.39, n.11, nov. 2004; 1111-11171678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6884/3940info:eu-repo/semantics/openAccess2014-09-03T17:57:23Zoai:ojs.seer.sct.embrapa.br:article/6884Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-03T17:57:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
