Resumo: | The study was carried out at the CNPGL/EMBRAPA, in the "Zona da Mata" region of Minas Gerais, Brazil, with the purpose of evaluating the effects of irrigation during the dry season on forage production, grass protein content, OM digestibility and aerial and basal tillering of the following cultivars of elephant grass (Pennisetum purpureum, Schum): Taiwan A-146, Mineiro, Cameroon, Elefante Pinda, Cana Africana, Mott and Kizozi. The experiment was arranged in a split-plot complete block design with two replications. Irrigation and lack of irrigation were the treatments studied in the plots, whereas the elephant grass cultivars were the ones examined in the sub-plots. Sprinkler irrigation which consisted of a 25 to 30 mm water sheet was applied from a uniform crosscut (19.06.88) to the beginning of the rainy season. Irrigation enhanced forage yield of all cultivars of elephant grass, but the seasonally of such a yield was hardly altered. In general, irrigation promoted increases in basal tillering bud did not influence the aerial one. There were no effects on forage quality. |

O delineamento experimental foi o de blocos ao acaso, com parcelas divididas, com duas repetições. Na parcela principal estudou-se o efeito da irrigação, e nas subparcelas, as cultivares de capim-elefante. A irrigação foi feita por aspersão, e correspondeu a uma lâmina de água de 25 a 30 mm, aplicada semanalmente desde o corte de uniformização (19.06.88) até o início das primeiras chuvas (06.10.88). A irrigação teve efeito positivo na produção de forragem de todas as cultivares, mas a estacionalidade desta produção foi pouco afetada. De maneira geral, a irrigação aumentou o perfilhamento basal e não teve efeito sobre o perfilhamento aéreo e sobre a qualidade da forragem produzida.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBotrel, Milton de AndradeAlvim, Maurílio JoséXavier, Deise Ferreira1991-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3519Pesquisa Agropecuaria Brasileira; v.26, n.10, out. 1991; 1731-1736Pesquisa Agropecuária Brasileira; v.26, n.10, out. 1991; 1731-17361678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3519/852info:eu-repo/semantics/openAccess2009-12-28T10:39:38Zoai:ojs.seer.sct.embrapa.br:article/3519Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2009-12-28T10:39:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
