Resumo: A greenhouse experiment was carried out to investigate the effect of Rhizobium inoculation and different sources of nitrogen (ammonium nitrate, ammonium sulphate, and urea) on yield, protein, and oil content of the two soybean varieties IAC 70-25 and Mineira. Inoculation increased seed yield and percent protein to the same extent as did nitrogen treatments, and decreased percent of oil in the variety Mineira. Inoculation had no effect on the variety IAC 70-25, although it increased the number of pod loci without increasing the number of seed in both soybean varieties. The different nitrogen sources increased yield, protein content, and decreased oil content in the variety Mineira. Neither the percent of oil nor the percent protein in the variety IAC 70-25 was influenced by nitrogen source. The variety Mineira may have potential for increased seed production, since it responded positively to inoculation and nitrogen treatments.

A cultivar Mineira respondeu à inoculação, aumentando a produção de sementes e o teor de proteína, tanto quanto os tratamentos que além da inoculação receberam nitrogênio, diminuindo, porém, o teor de óleo. A cultivar IAC 70-25, apesar de nodular eficientemente como a primeira, não apresentou aumento de produção no tratamento que recebeu somente inoculação. Esta cultivar, quando inoculada, apresentou menor número de sementes que nos demais tratamentos. A inoculação aumentou a percentagem de chochamento em ambas as cultivares, mais acentuadamente na IAC 70-25. As diferentes fontes de nitrogênio aumentaram a produção de sementes e o teor de proteína e diminuíram o teor de óleo na cultivar Mineira. A cultivar IAC 70-25 não apresentou diferenças entre os tratamentos quanto ao teor de óleo e proteína, mostrando, porém, maior percentagem de ácido linolênico no tratamento inoculado. Sugerem-se estudos da nodulação e fixação simbiótica do nitrogênio em diferentes épocas do desenvolvimento da planta para um melhor conhecimento da eficiência da simbiose em diferentes cultivares.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRuschel, Aláides PuppinSuhet, Allert RosaVianni, RomeuAlmeida, Dejair Lopes de2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17100Pesquisa Agropecuaria Brasileira; v.10, n.11, 1975: Série Agronomia; 19-23Pesquisa Agropecuária Brasileira; v.10, n.11, 1975: Série Agronomia; 19-231678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17100/11415info:eu-repo/semantics/openAccess2014-04-15T19:01:03Zoai:ojs.seer.sct.embrapa.br:article/17100Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:01:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
