Resumo: | An experiment to identify cultivars of buffel grass (Cenchrus ciliaris L.) well adapted to the semi-arid conditions of Northeast Brazil, was conducted from 1979 to 1983, at the Caatinga Experimental Field, of the Centro de Pesquisa Agropecuária do Trópico Semi-Árido (EMBRAPA/CPATSA). in Petrolina, Pernambuco State, Brazil. Thirteen cultivars of buffel grass, vegetatively established in 4 m x 2.5 m plots, were evaluated. The experimental design was randomized complete blocks with five replications. Among the highest cultivars, the cv. Molopo was the best one, 6,750 kg of dry matter/ ha-year, 106 cm height and good foliage Comparatively, the cv. Biloela, the most used at CPATSA, was short (97 cm) and less productive (5,355 kg of dry matter/ha-year). Among the cultivars of mean height, Gayndah was the shortest (77 cm) and F1 Hibrid 171 was the least productive (3,745 kg of dry matter/ha-year). Related to the nutritive value, expressed in crude protein in the dry matter, Gayndah and Molopo were the highest and the lowest, showing 12.43% and 9.51%, respectively. |

Foram avaliadas treze cultivares de capim buffel, estabelecidas vegetativamente em parcelas de 4 m x 2,5 m. O delineamento experimental adotado foi o de blocos ao acaso com cinco repetições. Entre as cultivares de porte alto, destacou-se a Molopo com maiores produtividades (6.750kg de matéria seca/ha-ano), relação colmo/folha e altura (106 cm). Comparativamente, a Biloela, que é atualmente a mais utilizada no CPATSA, apresentou menor altura (97 cm) e produtividade (5.355 kg de matéria seca/ha-ano). Entre as cultivares de porte médio, observou- se a Gayndah com menor altura (77 cm) e a F1 Hibrid 171, com menor produtividade (3.745 kg de matéria seca/ha-ano). Com relação ao valor nutritivo, temos a Gayndah (12,43%) e o Molopo (9,51%), com maior e menor teor de proteína bruta, na matéria seca, respectivamente.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Célia Maria M. de S.Oliveira, Martiniano C. deAlbuquerque, Severino G. de2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14375Pesquisa Agropecuaria Brasileira; v.22, n.5, maio 1987; 513-520Pesquisa Agropecuária Brasileira; v.22, n.5, maio 1987; 513-5201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14375/8278info:eu-repo/semantics/openAccess2014-10-03T18:37:28Zoai:ojs.seer.sct.embrapa.br:article/14375Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-03T18:37:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
