Resumo: The objective of this study was to evaluate the structure and forage production of hybrids of elephant-grass managed under cut. Twenty-four clones of elephant-grass from Embrapa dairy cattle were used as treatments, and Cameroom as a control. The grasses were cut close to the ground, every 60 days. The parameters evaluated were yield and dry matter content, number of basal tillers, number of leaves per tiller, plant height, stem diameter. The highest height of the plants was observed in clone CNPGL 00-103-1. The group with the highest number of tillers had three clones and a mean of 39.38 tiller m-2. In the group of clones CNPGL 00-103-1, CNPGL 93-25-3, CNPGL 00-16-1 and CNPGL 00-90-3 the highest dry matter contents (22.7% DM) were observed. The highest masses of forage, leaf blade and stem were observed in clone CNPGL 00-214, 15852 and 6195 kg ha-1 DM, respectively. The highest leaf blade / stem ratio was of the CNPGL 00-201-1 clone, and only in this did the leaf blade mass exceed that of the stem. Clone CNPGL 00-214 showed to be more productive, with high tillering capacity and forage accumulation.Keywords: Leaf blade; Pennisetum sp; stem; tiller.

Utilizaram-se como tratamentos 24 clones de capim-elefante provenientes da Embrapa Gado de Leite e o Cameroom como testemunha. Os capins foram cortados rentes ao solo, a cada 60 dias. Os parâmetros avaliados foram: produção e teor de matéria seca, número de perfilhos basais, número de folhas por perfilho, altura da planta, diâmetro do colmo. A maior altura das plantas foi observada no clone CNPGL 00-103-1. O grupo com maior número de perfilhos teve três clones e média de 39,38 perfilhos m-2. No grupo dos clones CNPGL 00-103-1, CNPGL 93-25-3, CNPGL 00-16-1 e CNPGL 00-90-3 foram observados os maiores teores de matéria seca (22,7% de MS). As maiores massas de forragem, de lâmina foliar e de colmo foram observadas no clone CNPGL 00-214, 15852 e 6195 kg ha-1 de MS respectivamente. A maior relação lâmina foliar/colmo foi do clone CNPGL 00-201-1 e apenas neste a massa de lâmina foliar foi superior à de colmo. O clone CNPGL 00-214 mostrou-se mais produtivo, com alta capacidade de perfilhamento e de acúmulo de forragem.Palavras-chave: Colmo; lâmina foliar; perfilho; Pennisetum sp.Universidade Federal de Goiás2019-10-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/46788Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 20 (2019): Continuous publication; 1-11Ciência Animal Brasileira / Brazilian Animal Science; v. 20 (2019): Publicação contínua; 1-111809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/46788/33810https://revistas.ufg.br/vet/article/view/46788/33811Copyright (c) 2019 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessEmerenciano Neto, João VirgínioBezerra, Marcio Gleybson da SilvaFrança, Alan Ferreira deAguiar, Emerson Moreira deDifante, Gelson dos santos2023-03-23T18:49:21Zoai:ojs.revistas.ufg.br:article/46788Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:18.276033Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
