Resumo: The effect of inoculation and different sources of nitrogen (potassium nitrate, ammonium sulphate, ammonium nitrate and urea) on nodulation, i.e., the number and weight of nodules, the symbiotic N-fixation and the amount of N, total and percentual, in the soybean plant (Glycine max (L.) Merril) was studied. Nodular weight decreased with addition of ammonium sulphate, ammonium nitrate and potassium nitrate to soil. This effect was not observed with urea. Although the number of nodules decreased with addition of these nitrogen sources, no inhibition of nitrogenase activity was noted. The plant dry weight measured at 45 days indicated no differences due to inoculation; however, inoculation proved effective as far as increase in total and percentual N in plant tops in all treatments under study. The increase in total nitrogen indicated a synergism of inoculation and nitrogen fertilization. Inoculation maintained a constant level of nitrogen in the plant throughout plant growth.

Merril). Houve redução da massa nodular com a aplicação de sulfato e nitrato de amônio e nitrato de potássio. Este efeito não foi observado com a uréia. O número de nódulos diminuiu com a adição de nitrogênio ao solo, porém, não foi observada inibição da atividade da nitrogenase. O peso seco da planta tomado até os 45 dias de idade não mostrou diferenças devidas à inoculação; no entanto a inoculação mostrou-se efetiva no sentido de aumentar o nitrogênio total e percentual da parte aérea da planta em todos os tratamentos estudados. A inoculação manteve o teor de nitrogênio constante durante todo o desenvolvimento da planta. Um efeito aditivo da inoculação e adubação nitrogenada foi observado no aumento do nitrogênio total da planta.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRushel, Alaídes PuppinRuschel, Renato2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17107Pesquisa Agropecuaria Brasileira; v.10, n.11, 1975: Série Agronomia; 37-40Pesquisa Agropecuária Brasileira; v.10, n.11, 1975: Série Agronomia; 37-401678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17107/11422info:eu-repo/semantics/openAccess2014-04-15T19:01:04Zoai:ojs.seer.sct.embrapa.br:article/17107Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:01:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
