Resumo: | Under tropical and subtropical conditions grass productivity is often limited by soil water and soil fertility. Therefore, the response of two cultivars of elephantgrass to irrigation and soil fertilization was investigated for two periods of the year - the wet and the dry seasons. The trial was conducted in the field in a region known as Baixada Fluminense located in the southern part of Rio de Janeiro State. In the wet period, the organic fertilizer (30 metric tons per hectare from poultry beds) was shown to be superior to both the mineral fertilizer (100 kg N. 100 kg P, 50 kg K/ha) and the check. Dry matter production for the organic fertilizer was 2.5 times higher (P < 0.01) than that obtained with mineral fertilizers. Contrary to what was expected, irrigation did not show any effect on grass production during the dry period. On the other hand, the cultivar Mineiro IPEACO produced 54% more dry matter and 30% more crude protein than the 'Gigante de Pinda' cultivar, despite the protein content of the former being higher. Also during the dry period, organic fertilization yielded more dry matter and protein than mineral fertilization. Irrigation, cultivar and fertilization interactions were also examined by the authors. |

No período chuvoso foi observada diferença significante (P < 0,01) entre as adubações; a adubação orgânica mostrou-se superior à mineral, que não diferiu do tratamento testemunha, e sua produção foi de aproximadamente duas vezes e meia a dos outros tratamentos. No período seco não foi constatada influência isolada da irrigação. O cultivar Mineiro IPEACO produziu mais 54% de matéria seca e 30% de proteína bruta por hectare que o cultivar Gigante de Pinda, embora este tenha apresentado teor de proteína maior que o daquele. A adubação orgânica determinou maior produção de matéria seca e proteína do que os outros dois tratamentos. Os autores analisam ainda as interações observadas entre irrigação, cultivares e adubação.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarvalho, Sylvio Romero deSilva, Aluízio Teixeira daCosta, Francisco AdemarSouto, Sebastião ManhãesLucas, Enésio Delgado de2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17071Pesquisa Agropecuaria Brasileira; v.10, n.4, 1975: Série Zootecnia; 23-30Pesquisa Agropecuária Brasileira; v.10, n.4, 1975: Série Zootecnia; 23-301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17071/11395info:eu-repo/semantics/openAccess2014-04-15T19:01:47Zoai:ojs.seer.sct.embrapa.br:article/17071Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:01:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
