Resumo: The objective of this work was to evaluate the effect of nitrogen and inoculation with Herbaspirullum seropedicae on maize (Zea mays) yield and nutrient contents in grains. The BRS 1030 and BRS 1060 simple hybrids received inoculation with the BR 11417 strain in the presence or absence of nitrogen‑fertilizer levels in a Typic Hapladult, during the periods of off-season (sowing in May 2012) and season (sowing in October 2012). In each season, the following treatments were evaluated: absolute control, without nitrogen fertilization or inoculation; inoculated control; doses of 50 and 100 kg ha‑1 N, without inoculation; and dose of 50 kg ha‑1 N plus inoculation. BRS 1030 produced 1,157 kg ha‑1 more grains than BRS 1060, in the joint analysis of both crop seasons. For the first genotype, the dose of 50 kg ha‑1 N with inoculation increased crop productivity by 2% in the off-season and by 4.5% in the season. The inoculation with H. seropedicae, BR 11417 strain, favors P accumulation in grains, but it has positive effect on yield only in combination with mineral N levels, which indicates that its effect is more important for maize growth promotion than for biological N fixation.

Os híbridos simples BRS 1030 e BRS 1060 receberam inoculação da estirpe BR 11417, na presença ou não de doses de adubação nitrogenada, em Argissolo Vermelho‑Amarelo distrófico, durante os períodos de entressafra (plantio em maio de 2012) e safra (plantio em outubro de 2012). Em cada época, os seguintes tratamentos foram avaliados: controle absoluto, sem adubação nitrogenada nem inoculação; controle com inoculação; doses de 50 e 100 kg ha‑1 de N, sem inoculação; e dose de 50 kg ha‑1 de N mais inoculação. BRS 1030 produziu 1.157 kg ha‑1 a mais de grãos que BRS 1060, na análise conjunta dos dois cultivos. Para o primeiro genótipo, a dose de 50 kg ha‑1 de N, com inoculação, incrementou em 2% a produtividade na entressafra e em 4,5% na safra. A inoculação de H. seropedicae, estirpe BR 11417, favorece o acúmulo de P nos grãos, mas tem efeito positivo sobre a produtividade somente em combinação com doses de N mineral, o que indica que seu efeito é mais destacado na promoção do crescimento do milho do que na fixação biológica de N.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), Embrapa e Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Breda, Farley Alexandre da FonsecaAlves, Gabriela CavalcantiReis, Veronica Massena2016-02-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/21219Pesquisa Agropecuaria Brasileira; v.51, n.1, jan. 2016; 45-52Pesquisa Agropecuária Brasileira; v.51, n.1, jan. 2016; 45-521678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/21219/13188https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/21219/13371Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-02-29T13:40:59Zoai:ojs.seer.sct.embrapa.br:article/21219Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-02-29T13:40:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
