Resumo: | The combined use of chemical fertilizers and organic materials have been recommended as alternative management, enabling the maintenance of high yields and stability. This study aimed to evaluate the influence of levels of manure applied in the row, with and without nitrogen application, in maize development and yield. The experiment was installed in Gurupi - TO, on March 6, 2009. The experimental design was randomized blocks in factorial scheme 8x2, where were used seven levels of manure (0.0; 10.0; 20.0; 30.0; 40.0; 50.0 and 60.0 t ha-1) and one treatment with chemical fertilizer and the second factor were two levels of nitrogen after planting. Were evaluating plants height weekly, from 15 to 57 days after emergency. Was evaluated final plant height, green matter and grain yield. Highest levels of manure led to significant increases in the evaluated characteristics. Nitrogen fertilization after planting promoted increase in grown rate, green mass and final plant height, even with the addition of organic manure. The manure application of 50 t ha-1 without of nitrogen after planting showed equivalent productivity to chemical fertilizer, however, with application of nitrogen after planting in the equivalent manure level was 45.4 t ha-1. When not applied nitrogen after planting, the chemical fertilizer produced grains and green mass equivalent to the highest manure levels, but application of nitrogen after planting in highest manure levels provided yield higher than chemical fertilizer. |

O uso combinado de fertilizantes químicos e materiais orgânicos têm sido recomendados como manejo alternativo, possibilitando a manutenção de altas produtividades com estabilidade de produção. Este trabalho teve como objetivo avaliar a influência de diferentes doses de esterco bovino aplicados na linha de semeadura, com e sem aplicação de nitrogênio em cobertura, no desenvolvimento e produtividade do milho. O experimento foi instalado no Campus experimental da UFT em Gurupi - TO, no dia seis de março de 2009. O delineamento experimental foi em blocos ao acaso em esquema fatorial 8x2, utilizando-se sete doses de esterco (0,0; 10,0; 20,0; 30,0; 40,0; 50,0 e 60,0 t ha-1) e um tratamento químico testemunha e, como segundo fator duas doses de nitrogênio em cobertura. Foram realizadas avaliações semanais de altura de plantas dos 15 aos 57 dias após a emergência. Foram avaliadas altura de plantas final, massa verde e produtividade de grãos. As maiores doses de esterco promovem aumentos significativos nas características avaliadas. O nitrogênio em cobertura promoveu aumentos nas taxas de crescimento de plantas, na produção de massa verde e altura final de plantas, mesmo com adição de adubação orgânica. A aplicação de 50 t ha-1 de esterco sem aplicação de cobertura resultou em produtividade equivalente à adubação química, enquanto com aplicação de N em cobertura a dose de esterco equivalente foi 45,4 t ha-1. Quando não se aplicou adubação nitrogenada em cobertura, a adubação química produziu massa verde e grãos equivalente as maiores doses de esterco, porém na aplicação de N em cobertura as maiores doses de esterco proporcionaram produtividades superiores a adubação química.UEL2011-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/382510.5433/1679-0359.2011v32n2p527Semina: Ciências Agrárias; Vol. 32 No. 2 (2011); 527-540Semina: Ciências Agrárias; v. 32 n. 2 (2011); 527-5401679-03591676-546Xreponame:Semina.
