Resumo: | The objective of this work was to evaluate methods of intercropping corn and Panicum spp. forages and their effects on corn yield and forage development. Two experiments with Panicum spp. were conducted, one with 'Tanzania' and other with 'Massai' in the municipality of Piracicaba, in the state of São Paulo, Brazil, in the 2012/2013 growing season. In both experiments, the treatments were: broadcast seeding of Panicum spp. at the same time of corn sowing; corn with Panicum spp. between rows; Panicum spp. sown with fertilizer; Panicum spp. sown between corn rows after corn establishment; broadcast seeding of Panicum spp. after corn establishment; and sole corn sowing. For corn, leaf nitrogen content, ear height, and grain yield were evaluated. For Panicum spp. cultivars, height, dry mass, tiller density, and leaf:stem ratio were evaluated. The intercropping establishment methods used do not affect corn growth, grain yield, and N leaf content. The seeding of both cultivars of Panicum spp. when corn plants had four expanded leaves reduces forage dry mass production and increases the leaf:stem ratio. The Panicum spp. broadcast method, performed after corn was established, does not allow appropriate establishment, with few plants in the area. |

Dois experimentos com Panicum spp. foram conduzidos, um com 'Tanzania' e outro com 'Massai' em Piracicaba, SP, na safra 2012/2013. Em ambos os experimentos, os tratamentos foram: Panicum spp. semeado a lanço no momento da semeadura do milho; milho com Panicum spp. nas entrelinhas; Panicum spp. semeado com fertilizante; Panicum spp. semeado nas entrelinhas depois do estabelecimento do milho; Panicum spp. semeado a lanço depois do estabelecimento do milho; e milho solteiro. Para o milho, avaliaram-se a concentração de nitrogênio foliar, a altura de espigas e a produtividade de grãos. Para as cultivares de Panicum spp., avaliaram-se altura, massa seca, número de perfilhos e relação folha:colmo. Os métodos de implantação do consórcio avaliados não afetam o crescimento, a produtividade de grãos e a concentração foliar de N do milho. A implantação das cultivares de Panicum spp., quando o milho apresenta quatro folhas expandidas, reduz a massa seca e aumenta a relação folha:colmo das plantas forrageiras. A semeadura a lanço de Panicum spp., depois do estabelecimento do milho, não permite o estabelecimento adequado, com poucas plantas na área.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Fundação de Amparo à Pesquisa do Estado de São Paulo (Fapesp)Almeida, Rodrigo Estevam Munhoz deGomes, Caio MacretLago, Bruno CoccoOliveira, Silas Maciel dePierozan Junior, ClovisFavarin, José Laércio2017-04-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/24111Pesquisa Agropecuaria Brasileira; v.52, n.3, mar. 2017; 170-176Pesquisa Agropecuária Brasileira; v.52, n.3, mar. 2017; 170-1761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/24111/13726Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2017-04-20T17:41:19Zoai:ojs.seer.sct.embrapa.br:article/24111Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2017-04-20T17:41:19Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |

The intercropping establishment methods used do not affect corn growth, grain yield, and N leaf content. The seeding of both cultivars of Panicum spp. when corn plants had four expanded leaves reduces forage dry mass production and increases the leaf:stem ratio. The Panicum spp. broadcast method, performed after corn was established, does not allow appropriate establishment, with few plants in the area. |
