Resumo: The effects of trifluralin upon soybean (Glycine max (L.) Merrill, cv. Paraná) nodulation and nitrogen uptake were studied in two soils, a 'Terra Roxa Estruturada" (clay) and a Dark-Red Latosol (loamy sand), in pots. Doses of 0, 1,2,3 or 4 1/ha of trifluralin were incorporated 8cm deep in the pots, and the soybean plants were harvested at 30, 60 and 90 days after seedling emergence, an nodulation and nitrogen uptake were evaluated. The results allowed for the conclusion that at the earlier stages of soybean growth, in the soil layer with trifluralin there was no nodule development. In the treated pots nodule formation ocurred deeper than in untreated pots. There was not evidence of a direct effect of trifluralin upon nitrogen uptake.

Merrill, cv. Paraná), cultivada em Terra Roxa Estruturada ou em Latossolo Vermelho-Escuro fase arenosa, em potes. O herbicida foi aplicado e incorporado à profundidade de 8 cm nos vasos. As avaliações foram feitas através de colheitas aos 30, 60 e 90 dias da emergência das plantas. Os resultados obtidos levaram à conclusão de que o herbicida causou redução do número de nódulos apenas nos estádios iniciais do desenvolvimento da planta, sendo que as plantas tratadas nodularam em profundidade maior que as testemunhas. Por outro lado, parece não ter ocorrido um efeito direto do herbicida sobre a absorção e translocação de N na planta de soja.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRosolem, Ciro AntonioNakagawa, JoãoMarcondes, Daniel A.S.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16336Pesquisa Agropecuaria Brasileira; v.20, n.11, nov. 1985; 1265-1271Pesquisa Agropecuária Brasileira; v.20, n.11, nov. 1985; 1265-12711678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16336/10557info:eu-repo/semantics/openAccess2014-04-16T19:38:17Zoai:ojs.seer.sct.embrapa.br:article/16336Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:38:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
