Resumo: The effects of different irrigation and nitrogen (N) on the chemical composition of Brachiaria brizantha var. Marandu were evaluated. The study was conducted at Embrapa Mid-North, located in the city of Parnaíba, Piauí. The treatments consisted of two irrigation levels (replacement of 50% and 80% of Class A pan evaporation - ECA) and four levels of nitrogen (200, 400, 600 and 800 kg N ha-1 ano-1), in a block randomized in a 2 x 4 factorial design with three replications. The irrigation 50% of class A pan evaporation promotes an increase in dry matter and reduces the levels of neutral detergent insoluble fiber (NDF) and acid detergent insoluble fiber (ADF), however, does not influence the content of crude protein, while the nitrogen confers increased protein levels and provides gross decrease in NDF and ADF of leaves, improving the nutritional value of the Marandu grass.

Marandu. O estudo foi conduzido na Embrapa Meio-Norte, localizada no município de Parnaíba, Piauí. Os tratamentos consistiram em duas lâminas de irrigação (reposição de 50% e 80% da Evaporação do Tanque Classe “A” - ECA) e quatro doses de nitrogênio (200, 400, 600 e 800 kg de N ha-1 ano-1), em um delineamento em blocos casualizados, em esquema fatorial 2 x 4, com três repetições. A lâmina de irrigação de 50% de evaporação do tanque classe A promove aumento nos teores de matéria seca e reduz os teores de fibra em detergente neutro (FDN) e de fibra em detergente ácido (FDA), porém não influencia o conteúdo de proteína bruta, ao mesmo tempo em que o nitrogênio confere aumento nos teores de proteína bruta e propicia diminuição nos teores de FDN e FDA das folhas, melhorando o valor nutritivo do capim-Marandu.UEL2015-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1536610.5433/1679-0359.2015v36n2p933Semina: Ciências Agrárias; Vol. 36 No. 2 (2015); 933-942Semina: Ciências Agrárias; v. 36 n. 2 (2015); 933-9421679-03591676-546Xreponame:Semina.
