Resumo: The objective of this work was to determine, in the soil‑plant system, the recovery efficiency of N derived from green manure applied on cabbage (Brassica oleracea) crop. The experiment was divided into two stages: the first one consisted of the straw production of jack bean (Canavalia ensiformis), velvet bean (Mucuna cinereum), and sorghum (Sorghum bicolor), in substrate enriched with 15N. The second stage consisted of the application of 15N-labeled green manure on the cabbage beds. Treatments consisted of: fresh residues of jack bean; fresh residues of velvet bean; fresh residues of sorghum; mixture of residues of jack bean, velvet bean, and sorghum at 1:1:1; and control without green manure addition. The N recovery in the soil–plant system was influenced by the green manure species used, and the recovery efficiency of the N derived from the green manure legumes varied from 9 to 16%. The jack bean treatment shows a greater recovery efficiency of nitrogen and, therefore, the best synchrony of N supply, by straw decomposition, with the cabbage crop demand.

O experimento foi dividido  em duas  etapas:  a primeira  consistiu da produção de palhada de feijão‑de‑porco (Canavalia ensiformis), mucuna‑cinza (Mucuna cinereum), e sorgo (Sorghum bicolor), em substrato enriquecido com 15N. A segunda etapa consistiu da aplicação das palhadas marcadas com 15N, em cobertura nos canteiros com repolho. Os tratamentos consistiram de: palha fresca de feijão‑de‑porco; palha fresca de mucuna‑cinza; palha fresca de sorgo; mistura das palhas de mucuna, feijão‑de‑porco e sorgo a 1:1:1; e controle sem adubação verde. A recuperação de N no sistema solo‑planta foi influenciada pelo tipo de palhada utilizado, e a eficiência de recuperação do N derivado da palhada de leguminosa variou de 9 a 16%. O  tratamento com palha de feijão‑de‑porco é o que apresenta maior eficiência de recuperação e, portanto, a melhor sincronia da oferta de nitrogênio pela decomposição da palhada com a demanda pela cultura do repolho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPERJ, CNPq e EMBRAPAFAPERJ, CNPq e EMBRAPAAraújo, Ednaldo da SilvaGuerra, José Guilherme MarinhoEspindola, José Antônio AzevedoUrquiaga, SegundoBoddey, Robert MichaelMartelleto, Luiz Aurélio PeresAlves, Bruno José Rodrigues2011-09-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/9911Pesquisa Agropecuaria Brasileira; v.46, n.7, jul. 2011; 729-735Pesquisa Agropecuária Brasileira; v.46, n.7, jul. 2011; 729-7351678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/9911/6385https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9911/5183info:eu-repo/semantics/openAccess2014-06-03T18:31:07Zoai:ojs.seer.sct.embrapa.br:article/9911Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-03T18:31:07Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
