Resumo: | The purpose of this study is to determine the growth, the solar radiation use efficiency, and the gross protein of sorghum forage under different cutting management. A unifactorial design in random blocks (cutting management) was used, varying from no-cut treatment to four cuts. The first cut occurred 44 days after sowing, the second one after 23 days of regrowth, the third one after 25 days of regrowth, and the last one after 40 days of regrowth. The efficiency of the sorghum forage’s solar radiation use reduces as the number of cuts increases. The sorghum forage’s gross protein increases with cutting management. Therefore, for a sorghum forage crop, it is recommended to restrain the cutting management up to three times during the crop cycle, since it has the biomass potential production, and the cuts should be made at every 25 days, depending on the increase of dry mass. After that, the cutting management should not be done, mainly due to the low radiation use efficiency, reduced dry mass accumulation, and low material quality.Keywords: forage; grazing; tillering. |

O objetivo deste trabalho foi determinar o crescimento, a eficiência do uso da radiação solar e a proteína bruta do sorgo forrageiro submetido a diferentes manejos de cortes. Foi utilizado um esquema unifatorial em delineamento de blocos casualizados (manejo de cortes), que variou do tratamento sem corte até quatro cortes. O primeiro corte ocorreu 44 dias após a semeadura, o segundo 23 dias após o rebrote, o terceiro 25 dias após o rebrote e o último após 40 dias do rebrote. A eficiência do uso da radiação solar do sorgo forrageiro reduziu com o aumento do número de cortes. A proteína bruta das plantas de sorgo aumentou com o manejo de cortes. Portanto, para a cultura do sorgo forrageiro, recomenda-se restringir o manejo de cortes para até três vezes durante o ciclo, desde que exista potencial produtivo de biomassa, e esses cortes devem ocorrer a cada 25 dias, dependendo do acréscimo de matéria seca. Não se recomenda a realização de mais do que três cortes, devido à baixa eficiência na utilização da radiação solar, à reduzida acumulação de matéria seca e à baixa qualidade desse material.Palavras-chave: foragem; pastagem; afilhamento.Universidade Federal de Goiás2019-04-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/46662Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 20 (2019): Continuous publication; 1-13Ciência Animal Brasileira / Brazilian Animal Science; v. 20 (2019): Publicação contínua; 1-131809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/vet/article/view/46662/32952https://revistas.ufg.br/vet/article/view/46662/32953Copyright (c) 2019 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessSchneider, Julia RenataCaron, Braulio OtomarElli, Elvis FelipeSchwerz, FelipeEngroff, Thaise Diemienger2023-03-23T18:49:21Zoai:ojs.revistas.ufg.br:article/46662Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:18.166654Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
