Resumo: The objective of this study was to assess the impact of nitrogen fertilization on M. maximus cv. Aruana cultivated in silvopastoral and full-sun systems, focusing on morphogenetic, structural, and productive traits, as well as chemical composition. Silvopastoral systems promote productive efficiency and sustainability in animal husbandry, leading to improved herbage quality and enhanced thermal comfort for the animals. Nitrogen fertilization affects the growth of tropical forages. The study evaluated the system used (silvopastoral or full sun), the presence of fertilization (with or without), and distinct intervals (21, 42, 63, or 84 days) on productive and morphogenetic traits of the forage. The silvopastoral system exhibited increased canopy height, while the full-sun condition favored dry matter production and animal weight gain. Fertilization benefited basal tiller density and morphogenesis. The crude protein content was higher in full sun. Full sun displayed benefits in terms of both herbage production and composition, whereas the silvopastoral system excelled particularly in terms of canopy height. Fertilization improved several traits, fostering tissue turnover. The study highlights the importance of proper management in silvopastoral systems to optimize herbage production and quality.

Sin embargo, el efecto de la fertilización nitrogenada no está bien dilucidado cuando se incluye en el sistema con el objetivo de aumentar la productividad vegetal y la calidad bromatológica. En este sentido, el objetivo del presente trabajo fue evaluar el efecto de la fertilización nitrogenada en M. maximus cv. Aruana cultivado en sistema silvopastoril o a pleno sol sobre características morfogénicas, estructurales, productivas y composición química. Este estudio se realizó durante 84 días y evaluó cuatro tratamientos: (1) Pastura de aruana a pleno sol con fertilización nitrogenada, (2) Pastura de aruana a pleno sol sin fertilización nitrogenada, (3) Pastura de aruana en sistema silvopastoril con fertilización nitrogenada y (4) Pastura de aruana en sistema silvopastoril sin fertilización nitrogenada pastoreada por ovinos en carga continua. La morfogénesis de las plantas fue influenciada por los tratamientos; la densidad poblacional de macollos aéreos y basales fue mayor con el uso de fertilización nitrogenada. El pleno sol promovió un mayor LAI, lo que tuvo un efecto directo sobre la capacidad fotosintética de las plantas. La producción de MS fue influenciada por la fertilización con N a pleno sol, promoviendo mayores valores de producción de materia seca total, masa forrajera y tasa de acumulación diaria. Los contenidos de MS, ADF y FDN fueron mayores sin el uso de fertilizante a diferencia de PB y lignina. El pleno sol y la fertilización nitrogenada favorecieron el desarrollo, crecimiento y composición química del forraje en comparación con el silvopastoreo.O objetivo do presente trabalho foi avaliar o efeito da adubação nitrogenada em M. maximus cv. Aruana cultivado em sistema silvipastoril e pleno sol sobre as características morfogênicas, estruturais, produtivas e composição química. Sistemas silvipastoris promovem eficiência produtiva e sustentabilidade na produção animal, melhorando a forragem e o conforto térmico. A adubação nitrogenada afeta o crescimento de forrageiras tropicais. O estudo avaliou o sistema utilizado (silvipastoril e pleno sol), adubação (com e sem) e períodos (21, 42, 63 e 84 dias) em características produtivas e morfogênicas da forrageira. O sistema silvipastoril elevou a altura do dossel, enquanto o pleno sol favoreceu a matéria seca e ganho de peso animal. A adubação beneficiou a densidade de perfilhos basais e morfogênese. O teor de proteína bruta foi maior no pleno sol. Pleno sol teve vantagens na forragem e composição, enquanto o silvipastoril destacou-se na altura do dossel. A adubação melhorou várias características, incentivando renovação tecidual. O estudo destaca a importância do manejo adequado em sistemas silvipastoris para otimizar produção e qualidade forrageira.UEL2023-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4832710.5433/1679-0359.2023v44n3p1207Semina: Ciências Agrárias; Vol. 44 No. 3 (2023); 1207-1224Semina: Ciências Agrárias; v. 44 n. 3 (2023); 1207-12241679-03591676-546Xreponame:Semina.
