Resumo: | The objective of this study was to evaluate the development of Brachiaria brizantha- MG-4; sown in two seasons and two seeding systems in space between two rows, and to evaluate the effect of intercropping on maize yield, as well as evaluating the physical properties of the soil after the consortium. The experiment was conducted in the agricultural year 2010, the Municipality of Quatro Pontes/PR. The experimental design was randomized blocks as a factorial 2x2, and an additional treatment that was corn cultivation single, with four replications. The treatments consisted two intercropping systems: corn intercropped with Brachiaria brizantha in the row, and corn intercropped with Brachiaria brizantha in space between two rows, and two times of sowing Brachiaria brizantha: simultaneously corn, and twenty-five days after sowing corn. The seed was planted mechanically in no-tillage system, with spacing between the lines of 0,70 m. The ears were harvested by hand and in the laboratory were evaluated: yield components and productivity. Brachiaria brizantha- MG-4 was sown and harvested manually. We evaluated the production of fresh and dry mass and yield components. For soil analyzes the soil was sampled at 0-0.10 and 0,10-0,20 m. Were determined the total porosity, macroporosity and microporosity. The results demonstrated that the production components of Brachiaria brizantha were lower when it was sown twenty-five days after sowing corn, and between sowing systems when Brachiaria brizantha was sown in line. There was no reduction in grain yield of maize intercropped with Brachiaria system independent and sowing date. The consortium of pasture with corn increased the total porosity, and reduced soil bulk density. |

MG-4; semeada em duas épocas e dois sistemas de semeadura, na linha e na entrelinha da cultura do milho; avaliar o efeito do consórcio na produtividade do milho, bem como avaliar as propriedades físicas do solo após o consórcio. O experimento foi conduzido no ano agrícola de 2010, no Município de Quatro Pontes/ PR. O delineamento experimental foi de blocos ao acaso, em esquema fatorial 2x2, mais um tratamento adicional que foi o cultivo do milho solteiro, com quatro repetições. Os tratamentos constituíram de dois sistemas de cultivo: cultivo do milho com braquiária na linha de semeadura e cultivo do milho com braquiária na entrelinha; e duas épocas de semeadura da braquiária: simultaneamente ao milho e vinte e cinco dias após semeadura do milho. O milho foi semeado mecanicamente em sistema de plantio direto; com espaçamento nas entrelinhas de 0,70 m. As espigas foram colhidas manualmente e no laboratório foram avaliadas: os componentes de produção e a produtividade. A Brachiaria brizantha cv. MG-4 foi semeada e colhida manualmente. Avaliou-se a produção de massa verde e seca e os componentes de produção. Para análises físicas do solo foram coletadas amostras nas profundidades de 0-0,10 e 0,10- 0,20 m. Foram determinados a porosidade total, a macroporosidade e microporosidade. Os resultados demonstraram que os componentes de produção da braquiária foram menores quando esta foi semeada vinte e cinco dias após a semeadura do milho, e entre os sistemas de semeadura quando a braquiária foi semeada na linha do milho. Não houve redução na produtividade de grãos de milho em consórcio com a braquiária, independente do sistema e época de semeadura. O consórcio de braquiária com milho promoveu aumento na porosidade total do solo e redução na densidade do solo.UEL2014-02-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1055010.5433/1679-0359.2014v35n1p55Semina: Ciências Agrárias; Vol. 35 No. 1 (2014); 55-66Semina: Ciências Agrárias; v. 35 n. 1 (2014); 55-661679-03591676-546Xreponame:Semina.
