Resumo: The objective of this study was to evaluate the influence of different nitrogen doses on the forage accumulation, tillering and chemical characteristics of Braquiaria grass (Urochloa decumbens (Stapf) Webster cv. Basilisk). A randomized block design with four replications was used, and each plot (50 m²) was an experimental unit. The treatments consisted of four doses of N (100, 200, 300 and 400 kg ha-1year-1) and the control treatment. There was an increase in whole-plant crude protein (CP) and in leaf crude protein (LCP) and a decrease in whole-plant neutral detergent fiber (NDF) and leaf neutral detergent fiber (LNDF). Total dry matter accumulation (TDMA) and dry matter accumulation rate (DMAR) increased linearly in response to the N doses applied. Nitrogen fertilization promotes benefits such as increased biomass accumulation and improved forage chemical composition and tillering in Brachiaria grass.

Basilisk). Foi utilizado o delineamento experimental em blocos ao acaso, com quatro repetições, sendo cada parcela (50 m²) a unidade experimental. Os tratamentos consistiram em quatro doses de N: 100, 200, 300 e 400 kg ha-1 ano-1 e o tratamento-controle. Houve aumento da proteína bruta da planta inteira (PBT) e da proteína bruta das folhas (PBF), e redução da fibra em detergente neutro da planta inteira (FDNT) e das folhas (FDNF). O acúmulo total de matéria seca (ATMS) e a taxa de acúmulo de matéria seca (TACUMS) aumentaram linearmente em resposta às doses de N aplicadas. A adubação nitrogenada promove benefícios, como o aumento de acúmulo de massa e a melhoria da composição química de forragem, e o perfilhamento no capim-braquiária.FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorOutra AgênciaengUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASCientíficaCapim-braquiariaAdubos e fertilizantesFertilizantes nitrogenadosForragemFertilizaçãoProdução de massaUrochloaValor nutricionalForage accumulation, tillering and bromatological characteristics of Brachiaria grass under nitrogen fertilizationAcúmulo de forragem, perfilhamento e características bromatológicas do capim-braquiária sob adubação nitrogenadainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleSilvia Layse Mendes MachadoEleuza Clarete Junqueira de SalesSidnei Tavares dos ReisVirgílio Gomes MesquitaZaqueu Gonçalves CarvalhoFlávio Pinto MonçãoEdilane Aparecida da Silva GomesDomingos Savio QueirozAntônio Carlos Ribeiro Lima llinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
