Resumo: This work was carried out at FCAV-UNESP, Jaboticabal, SP, Brazil, to evaluate growth physiological characteristics, dry matter production, contents of crude protein and acid detergent fiber and the IVDMD of two genotypes of Pennisetum americanum (cv. Comum and CMS 02/EMBRAPA). Genotypes were sown in November/94 and March/95 and submitted to four nitrogen levels (0; 75; 150 and 225 kg ha-1) as ammonium nitrate. A split plot design, with three replications was used. In the first sowing time, the cv. Comum presented higher (P < 0.05) total dry-matter production (6,995 kg ha-1) than the genotype CMS 02 (6,177 kg ha-1). The application of 150 kg ha-1 was considered adequate during this period. In the second sowing time, the average total DM productions of the genotypes (2,799 kg ha-1) were similar and the nitrogen fertilization did not show any significative effect. In the first two cuts of the first sowing time the plants presented a high production of leaves with contents of crude protein higher than 20% and values of IVDMD around 70%.

O delineamento experimental adotado foi o de blocos ao acaso, com parcelas subdivididas, e três repetições. Na primeira época de semeadura, a cv. Comum apresentou produção de MS total significativamente superior (6.995 kg ha-1) à do genótipo CMS 02 (6.177 kg ha-1), e a aplicação de 150 kg ha-1 foi a dose mais adequada nesse período. Na segunda época de semeadura, a produção de MS total dos genótipos foi, em média, de 2.799 kg ha-1, e a adubação nitrogenada não revelou efeito significativo. Plantas da primeira época de semeadura apresentaram, nos dois primeiros cortes, alta produção de folhas, cujos teores de PB foram superiores a 20%, e os valores de DIVMS em torno de 70%.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGuideli, ClaudiaFavoretto, VanildoMalheiros, Euclides Braga2000-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5994Pesquisa Agropecuaria Brasileira; v.35, n.10, out. 2000; 2093-2098Pesquisa Agropecuária Brasileira; v.35, n.10, out. 2000; 2093-20981678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5994/3098info:eu-repo/semantics/openAccess2014-08-19T19:55:21Zoai:ojs.seer.sct.embrapa.br:article/5994Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-19T19:55:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
