Resumo: The objective of this work was to evaluate the compatibility of seed treatment with fungicides and Bradyrhizobium strains inoculation for cowpea. Cell survival on seeds of cultivar BRS Guariba treated or not with fungicides (fludioxonil, carbendazim, carbendazim + thiram, and carboxin + thiram) and inoculated or not with Bradyrhizobium (strains UFLA3‑84, BR 3267, INPA3‑11B, and BR 3262) were evaluated in laboratory. Another experiment was carried out in greenhouse, in Leonard jars, using the same treatments. The following were evaluated: shoot dry matter weight, besides number and dry matter weight of nodules 25 days after plant emergence. Two experiments were performed in the field with the strain BR 3262, with fungicides on the seeds: one in a first cultivation area and the other in an area previously cultivated with annual crops. Nodule number, nodule dry weight, and shoot dry matter weight were evaluated at 35 days, and grain yield at harvest. Fungicides did not have significant effect on Bradyrhizobium survival, plant nodulation, and grain yield, which was, in average, higher than 1,200 kg ha‑1. Cowpea seed treatment with fungicides is compatible with the inoculation of the evaluated strains.

Em laboratório, avaliou-se a sobrevivência de células nas sementes da cultivar BRS Guariba, tratadas ou não com fungicidas (fludioxonil, carbendazim, carbendazim + thiram e carboxin + thiram) e inoculadas ou não com Bradyrhizobium (estirpes UFLA3‑84, BR 3267, INPA3‑11B e BR 3262). Em casa de vegetação, conduziu-se experimento em vasos de Leonard, com os mesmos tratamentos. Foram avaliados: massa de matéria seca da parte aérea, além de número e massa de nódulos 25 dias após a emergência das plantas. No campo, dois experimentos foram conduzidos, tendo-se utilizado a estirpe BR 3262, com aplicação de fungicidas nas sementes: um em área de primeiro cultivo e outro em área cultivada anteriormente com culturas anuais. Avaliaram-se, aos 35 dias, o número de nódulos, a massa de nódulos secos e a massa de matéria seca da parte aérea, e, na colheita, a produtividade de grãos. Os fungicidas não tiveram efeito significativo sobre a sobrevivência de Bradyrhizobium, a nodulação das plantas e o rendimento de grãos, que, em média, foi superior a 1.200 kg ha‑1. O tratamento de sementes de feijão‑caupi com fungicidas é compatível com a inoculação das estirpes avaliadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapaCapesSilva Neto, Manoel Luis daSmiderle, Oscar JoséSilva, Krisle daFernandes Júnior, Paulo IvanXavier, Gustavo RibeiroZilli, Jerri Édson2013-03-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13241Pesquisa Agropecuaria Brasileira; v.48, n.1, jan. 2013; 80-87Pesquisa Agropecuária Brasileira; v.48, n.1, jan. 2013; 80-871678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13241/8972https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13241/9005info:eu-repo/semantics/openAccess2013-03-19T19:06:00Zoai:ojs.seer.sct.embrapa.br:article/13241Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-03-19T19:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
