Resumo: The objective of this work was to evaluate irrigation strategies on elephantgrass (Pennisetum purpureum) pasture, during the dry season, upon dry matter yield, plant height, ground cover, and forage quality. The experiment was conducted in the county of Coronel Pacheco, Minas Gerais, Brazil, from June/2004 to January/2007. The treatments evaluated were: treatments with irrigation starting on Jul. 15, Aug. 1st, Aug. 15, Sept. 1st, Sept. 15, and Oct. 1st fertilized with 300 kg ha-1 of N per year, and two control treatments (without irrigation) fertilized with 300 and 200 kg ha-1 of N per year. Two harvest methods were used: hand plucking maintaining a forage stubble height of 80–100 cm and cutting at 10 cm above the soil surface. Both dry matter yield and plant height increased with the earliness of irrigation onset. Pastures with irrigation onset in July and August were ready for grazing four to six weeks earlier than those without irrigation. Dry matter yield obtained by cutting was double that obtained by hand plucking. Crude protein content and in vitro dry matter digestibility were higher with hand plucking than by cutting, but neutral detergent fiber contents were similar.

O experimento foi realizado em Coronel Pacheco, MG, de junho /2004 a janeiro/2007, e os tratamentos foram: irrigações a partir de 15/7, 1o/8, 15/8, 1o/9, 15/9 e 1o/10, com adubação de 300 kg ha-1 de N por ano; com dois tratamentos sem irrigação, adubados com 300 e 200 kg ha-1 de N por ano. Foram usados dois métodos de colheita: corte a 10 cm do solo e pastejo simulado, realizado acima da altura de resíduo (80–100 cm). A produção de matéria seca e a altura das plantas aumentaram com as irrigações iniciadas em julho e agosto. As pastagens irrigadas a partir de julho e agosto atingiram condições de pastejo quatro a seis semanas antes que as dos tratamentos não irrigados. A produção de matéria seca obtida pelo método do corte foi duas vezes superior àquela obtida pelo pastejo simulado. Os teores de proteína bruta e a digestibilidade in vitro da matéria seca foram maiores no pastejo simulado do que no corte, mas os teores de fibra em detergente neutro foram semelhantes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPqCóser, Antônio CarlosMartins, Carlos EugênioDeresz, FerminoFreitas, Ary Ferreira dePaciullo, Domingos Sávio CamposAlencar, Carlos Augusto Brasileiro deVítor, Cláudio Manoel Teixeira2008-12-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/729Pesquisa Agropecuaria Brasileira; v.43, n.11, nov. 2008; 1625-1631Pesquisa Agropecuária Brasileira; v.43, n.11, nov. 2008; 1625-16311678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/729/5565https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/729/498info:eu-repo/semantics/openAccess2012-06-17T11:45:10Zoai:ojs.seer.sct.embrapa.br:article/729Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:45:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
