Resumo: | Increases in the soybean grain yield without significant alterations in the production cost can be achieved with variations in the spatial plant arrangement. The sowing in crossed rows has aroused the interest of Brazilian soybean producers once this practice was used in some areas with record-breaking soybean yield in Brazil in 2010/11 and 2011/12 growing seasons. This study aimed to evaluate the agronomic performance of soybean cultivars with determinate growth habit managed under different spatial plant arrangements, including crossed rows. The experiments were carried out in Londrina, PR, at 2011/12 and 2012/13 growing seasons. A randomized complete block experimental design in a 2x2x2 factorial scheme was used, with three replications. The treatments were formed by combining two row spacing (0.4 and 0.6 m), two seeding rates (375,000 and 562,500 seeds ha-1) and two sowing systems (crossed or parallel rows).The cultivar BRS 294 RR was used in 2011/12 and BRS 295 RR in 2012/13 growing season. In both cultivars and years the grain yield was not affected by the sowing system, seeding rate, or by the interactions among factors, showing the high soybean phenotypic plasticity. Row spacing of 0.6 m showed the highest soybean grain yield in BRS 294 RR, mainly due to a higher grain production in the branches. |

A técnica denominada “semeadura cruzada” vem despertando interesse no setor produtivo por ter sido utilizada por alguns recordistas de produtividade de soja no Brasil. O objetivo desse trabalho foi avaliar o desempenho agronômico de cultivares de soja com tipo de crescimento determinado, em diferentes arranjos de plantas. Os experimentos foram conduzidos em Londrina, PR, nas safras 2011/12 e 2012/13, sob o delineamento de blocos completos ao acaso, em esquema fatorial 2x2x2, com três repetições. Os tratamentos foram formados pela combinação de dois espaçamentos entre fileiras (0,4 e 0,6 m), duas densidades de semeadura (375.000 e 562.500 sementes ha-1) e de dois sistemas de semeadura (semeadura cruzada e não cruzada). Na safra 2010/11, utilizou-se a cultivar BRS 294 RR e na safra 2011/12 a cultivar BRS 295 RR. Nas duas safras, a produtividade de grãos não foi influenciada pelo sistema de semeadura, pela densidade de plantas e pela interação entre esses fatores, o que demonstra a alta plasticidade fenotípica das cultivares utilizadas. Para a cultivar BRS 294 RR, o espaçamento de 0,6 m entre fileiras conferiu maior produtividade de grãos em relação ao espaçamento de 0,4 m, principalmente porque proporcionou aumento da produção de grãos oriunda dos ramos.UEL2015-06-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1490010.5433/1679-0359.2015v36n3p1215Semina: Ciências Agrárias; Vol. 36 No. 3 (2015); 1215-1226Semina: Ciências Agrárias; v. 36 n. 3 (2015); 1215-12261679-03591676-546Xreponame:Semina.
