Summary: – The objective of this work was to evaluate the efficiency and reliability of methods to estimate edible forage dry matter on an elephant grass pasture (Pennisetum purpureum Schumach.). Visual comparative yield method (VCYM) and hand plucking (HP) were used. Two samplings, one in March 20, and another in April 5, 2001, with one and four observers for HP and VCYM, respectively, were done. Estimates of edible forage dry matter were analysed by linear regression and the average estimates were compared by using F test with a probability level of 1%. There was no difference between the two sampling methods. Both, VCYM and HP were efficient to estimate potentially edible forage in the elephant grass pasture. The observers training is decisive, especially when VCYM is used.

Foram usados o método do rendimento visual comparativo (MRVC) e o método do pastejo simulado (PSIM). Foram realizadas amostragens em 20 de março e 5 de abril de 2001, com um e quatro observadores para PSIM e MRVC, respectivamente. As estimativas obtidas foram analisadas por meio de regressão linear da produção de matéria seca em razão dos padrões estimados e as médias comparadas pelo teste F, a 1% de probabilidade. Não houve diferença entre os métodos. Tanto o MRVC como o PSIM podem ser recomendados para estimar a forragem potencialmente consumível em pastagem de capim-elefante. O treinamento dos avaliadores torna-se decisivo, especialmente quando o MRVC estiver sendo utilizado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCóser, Antônio CarlosMartins, Carlos EugênioDeresz, FerminoFreitas, Ary Ferreira dePaciullo, Domingos Sávio CamposSalvati, José AugustoSchimidt, Lilian Tavares2003-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6648Pesquisa Agropecuaria Brasileira; v.38, n.7, jul. 2003; 875-879Pesquisa Agropecuária Brasileira; v.38, n.7, jul. 2003; 875-8791678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6648/3705info:eu-repo/semantics/openAccess2014-08-11T17:09:07Zoai:ojs.seer.sct.embrapa.br:article/6648Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T17:09:07Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
