Resumo: This study aimed to evaluate the initial heights (10, 20, and 30 cm) and deferment periods (171, 141, and 109 days in 2010; and 131, 100, and 71 days in 2011) of Urochloa decumbens cv. Basilisk (signal grass). The factors were arranged in split plot, in a randomized complete block design with three replications. Pastures deferred for a short period had lower masses of forage (5,977 and 6,904 kg/ha of DM in 2010 and 2011, respectively). In 2010, pastures deferred for a short period had lower mass of live stem (942 kg/ha of DM), dead leaf blade (785 kg/ha of DM), and dead stem (1282 kg/ha of DM), higher number of vegetative tillers (797 tillers/m²), fewer reproductive tillers (2 tillers/m²), less falling index (1.4), higher mass of live leaf blade (655 kg/ha of DM). The higher pastures had fewer vegetative tillers (495 and 431 tillers/m² in 2010 and 2011, respectively), larger masses of forage (5,285 and 5,942 kg/ha of DM in 2010 and 2011, respectively), dead leaf blade (968 kg kg/ha of DM in 2010) and dead stem (1,902 kg/ha of DM in 2010). Based on the results obtained in the two years, for use in July, the signal grass can be deferred for 71-109 days with an initial height of 20 to 30 cm. The initial height of 10 cm is recommended when a deferral period above 130 days is adopted.Keywords: Brachiaria decumbens; forage mass; sward height; tiller.

Basilisk (capim-braquiária). Os fatores foram arranjados em parcelas subdivididas e em delineamento de blocos completos casualizados, com três repetições. Os pastos diferidos por curto período apresentaram menores massas de forragem (5.977 e 6.904 kg/ha de MS em 2010 e 2011, respectivamente). Em 2010, os pastos diferidos por curto período apresentaram menor massa de colmo vivo (942 kg/ha de MS), de lâmina foliar morta (785 kg/ha de MS) e de colmo morto (1.282 kg/ha de MS), maiores números de perfilhos vegetativos (797 perfilhos/m²) e menores de reprodutivos (2 perfilhos/m²), menor índice de tombamento (1,4) e superior massa de lâmina foliar viva (655 kg/ha de MS). Os pastos mais altos apresentaram menor número de perfilhos vegetativos (495 e 431 perfilhos/m² em 2010 e 2011, respectivamente), maiores massas de forragem (5.285 e 5.942 kg/ha de MS em 2010 e 2011, respectivamente), de lâmina foliar morta (968 kg/ha de MS em 2010) e de colmo morto (1.902 kg/ha de MS em 2010). Com base nos resultados obtidos nos dois anos, para utilização em julho, o capim-braquiária pode ser diferido por 71 a 109 dias, com altura inicial de 20 a 30 cm. A altura inicial de 10 cm é recomendada quando se adota período de diferimento acima de 130 dias.Palavras-chave: estrutura do pasto; massa de forragem; perfilho; Urochloa decumbens.Universidade Federal de Goiás2017-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo CientíficoResearchapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/e-4374410.1590/cab18043744Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 18 (2017): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 18 (2017): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/e-43744/24325https://revistas.ufg.br/vet/article/view/e-43744/24326Copyright (c) 2017 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessGouveia, Francisco de SouzaFonseca, Dilermando Miranda daSantos, Manoel Eduardo RozalinoGomes, Virgilio MesquitaCarvalho, Angélica Nunes de2023-06-07T18:48:26Zoai:ojs.revistas.ufg.br:article/43744Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:16.028529Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
