Resumo: | The aim of this work was to evaluate the effect of nitrogen application mode and spacing on corn culture. The study was carried out in 2003/04 agricultural years, at the Experimental Station of Coimbra – UFV. The experiment was installed in a complete randomised block design. Treatments were arranged in a 3 x 3 x 2 factorial scheme with four replicates (three cultivates - UFVM 100, AG 9010 and AG 1051; three nitrogen application modes - 0, 120 kg ha-1 of N in planting and 30 kg ha-1 at sowing + 90 kg ha-1 at four fully expanded leaves; and two plant spacing – 1.0 and 0.5 m). Either at sowing or parcel out, the nitrogen application increased the plant height in all plant spacing used; the spacing reduction, from 1.0 m to 0.50 m, provided an increase of 8% in grains productivity; the 120 kg ha-1 nitrogen application, either at sowing or divided in two modes (30 kg ha-1 at sowing and 90 kg ha-1 at four fully expanded leaves), did not show any effect on the characteristics evaluated. |

A pesquisa foi desenvolvida no ano agrícola 2003/04, na Estação Experimental de Coimbra – UFV, em um experimento disposto no delineamento de blocos casualizados, com 4 repetições, no esquema fatorial 3 x 3 x 2 (3 cultivares – UFVM 100, AG 9010 e AG 1051, 3 modos de aplicação do nitrogênio – 0, 120 kg ha-1 de N no plantio e 30 kg ha-1 de N no plantio + 90 kg ha-1 de N, na quarta folha completamente expandida, e 2 espaçamentos entre fileiras – 1,0 e 0,5 m). A aplicação de nitrogênio, parcelado ou todo no plantio, elevou a altura de plantas das cultivares, independentemente do espaçamento; o espaçamento de 0,50 m, proporcionou aumento de 8% na produtividade de grãos; não houve diferença significativa na produtividade de grãos das cultivares estudadas com a aplicação de 120 kg ha-1 de N no plantio ou parcelado (30 kg ha-1 de N no plantio + 90 kg ha-1 de N, na quarta folha completamente expandida).Universidade Estadual de Maringá2008-02-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/41510.4025/actasciagron.v29i4.415Acta Scientiarum.
