Resumo: | The objective of this study was to evaluate the structural and productive features of Panicum maximum cultivars (Tanzânia, Mombaça, Massai, and Zuri) in three rest periods (30, 45 and 60 days), in the semiarid region of Brazil. The experiment was carried out in a completely randomized design with three replicates. The length of the leaf blade and the diameter of the stem increased as a function of the cut intervals. Leaf blade width and number of live leaves (3.86 leaves tiller-1) were not affected by cut intervals. The height of the canopy increased with the ages, with effect in the mass of forage, being the cv. Zuri the most productive with 148,75 cm e 18.297,49 kg ha-1 DM at 60 days. The highest masses of leaves and stems were obtained in the longest rest period, while the leaf/stem ratio decreased. In the cut-off interval of 45 days, the cultivars of Panicum maximum have shown satisfactory yield, and the smaller cut interval provides a reduction in canopy height and stem thickness. |

O experimento foi realizado em delineamento inteiramente ao acaso, com três repetições. O comprimento da lâmina foliar e o diâmetro do colmo aumentaram em função dos intervalos de corte. A largura da lâmina foliar e o número de folhas vivas (3,86 folhas/perfilho) não foram afetados pelos intervalos de corte. A altura do dossel aumentou com as idades, com efeito na massa de forragem, sendo a cv. Zuri superior com 148,75 cm e 18.297,49 kg/ha de MS, aos 60 dias. As maiores massas de lâminas e colmos foram obtidas no maior período de rebrotação, enquanto que a relação folha/colmo diminuiu. No intervalo de corte de 45 dias, as cultivares de Panicum maximum apresentaram produção satisfatória, sendo que o menor intervalo de corte proporciona redução na altura do dossel e na espessura do colmo.EDUFU2019-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3640210.14393/BJ-v35n3a2019-36402Bioscience Journal ; Vol. 35 No. 3 (2019): May/June; 682-690Bioscience Journal ; v. 35 n. 3 (2019): May/June; 682-6901981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/36402/26100Brazil; ContemporaryCopyright (c) 2019 Jacqueline dos Santos Oliveira, João Virgínio Emerenciano Neto, Gelson dos Santos Difante, Fabio Nunes Lista, Rodrigo da Silva Santos, Jessica Daisy do Vale Bezerra, Breno Ramon de Souza Bonfim, Larissa Bezerra Soares Milhomens, Juliani Stephanie Medeiros Ribeirohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOliveira, Jacqueline dos Santos Emerenciano Neto, João VirgínioDifante, Gelson dos Santos Lista, Fabio Nunes Santos, Rodrigo da Silva Bezerra, Jessica Daisy do Vale Bonfim, Breno Ramon de Souza Milhomens, Larissa Bezerra Soares Ribeiro, Juliani Stephanie Medeiros 2022-01-31T22:58:49Zoai:ojs.www.seer.ufu.br:article/36402Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-31T22:58:49Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
