Resumo: | Currently, the practice of Crop-Livestock Integration is stimulated as a way of increasing the generation of foreign exchange for Brazil. Integrated systems improve land use efficiency as well as preserve, recover and increment or soil fertility. The aim of this research was to evaluate how different doses of nitrogen fertilization can affect production and quality of dual purpose wheat submitted to grazing. The experimental designed was randomized block with five treatments (0, 75, 150, 225 and 300 Kg N ha-1, like ammonium nitrate) and four repetitions. The forage yield, the percentage crude protein (P=.0001) and acid detergent insoluble protein (P=.0054) had a linear increased because of the nitrogen addition doses. The crude protein percentage changed the estimate of all soluble carbohydrates (P=.0001) and non-fibrous carbohydrates (P=.0186), but did not influence the, nitrogen detergent fiber corrected with ash and proteins percentage contributing for content cell. The crops production (P=.0001) and the number of kernels per ear (P=.0001) showed significantly difference because of the nitrogen additions dose, increasing the number of fertile flowers. The nitrogen topdressing alters forage production, the chemical composition and the production of dual purpose wheat grains subjected to grazing. |

Os sistemas integrados melhoram a eficiência de uso da terra, bem como preservam, recuperam e/ou incrementam a fertilidade do solo. Objetivou-se avaliar a produção e a composição bromatológica de trigo duplo propósito (TDP) manejado sob pastejo com diferentes doses de nitrogênio em cobertura (DAN): 0, 75, 150, 225 e 300 Kg de N ha-1, sob a forma de nitrato de amônia. Utilizou-se delineamento experimental de blocos casualizados com quatro repetições. A produção de forragem e os teores de proteína bruta (P=0,001) e proteína insolúvel em detergente ácido aumentaram (P=0,0054) linearmente, em função das DAN. O teor de proteína bruta (P=0,0001) impactou sobre as estimativas de carboidratos totais e de carboidratos não fibrosos, mas não influenciou (P=0,0186) os teores de fibra em detergente neutro corrigidas para cinzas e proteínas contribuindo para manutenção dos teores de conteúdo celular. A produção de grãos P=(0,0001) e o número de grãos por espigas diferiram (P=0,0001), em função das DAN, aumentando o número de flores férteis. A adubação nitrogenada em cobertura altera a produção de forragem, a composição bromatológica e a produção de grãos de trigo duplo propósito submetido à pastejo.UEL2016-04-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2168610.5433/1679-0359.2016v37n2p1091Semina: Ciências Agrárias; Vol. 37 No. 2 (2016); 1091-1100Semina: Ciências Agrárias; v. 37 n. 2 (2016); 1091-11001679-03591676-546Xreponame:Semina.
