Resumo: | The objective of this work was to assess management targets for marandu palisade grass (Urochloa brizantha cv. Marandu) subjected to rotational stocking and to nitrogen fertilization rates, from January 2009 to April 2010. Treatments consisted of a combination of two grazing frequencies (pre-grazing heights of 25 and 35 cm) and two levels of nitrogen application (50 and 200 kg ha-1 per year). in a completely randomized block design, in a 2x2 factorial arrangement, with four replicates. The established post-grazing height was 15 cm. Greater values of daily weight gain per animal per day (0.629 and 0.511 kg day-1), weight gain per hectare (886 and 674 kg ha-1), and stocking rate (3.13 and 2.85 AU ha-1) were found for pre-grazing height of 25 cm. The application of 200 kg ha-1 of N increased the percentage of leaves in post-grazing forage mass, forage accumulation rate, stocking rate, as well as weight gain per hectare. The best grazing strategy corresponds to the pre-grazing height of 25 cm, regardless of the nitrogen application. |

Marandu) submetido a pastejo rotativo e a doses de nitrogênio, de janeiro de 2009 a abril de 2010. Os tratamentos consistiram da combinação de duas frequências de pastejo (altura pré-pastejo de 25 e 35 cm) e de duas doses de fertilizante nitrogenado (50 e 200 kg ha-1 por ano) em delineamento de blocos ao acaso com arranjo fatorial 2x2 e quatro repetições. A altura de pós-pastejo estipulada foi de 15 cm. Maiores valores de ganho de peso médio por animal por dia (0,629 e 0,511 kg dia-1) e por hectare (886 e 674 kg ha-1), bem como de taxa de lotação (3,13 e 2,85 UA ha-1), foram observados nos pastos manejados com altura pré-pastejo de 25 cm. A aplicação de 200 kg ha-1 de N resultou em aumentos na percentagem de folhas na massa de forragem pós-pastejo, nas taxas de acúmulo de forragem, na taxa de lotação e no ganho de peso por área. A mais adequada estratégia de manejo corresponde à altura pré-pastejo de 25 cm, independentemente da dose de nitrogênio utilizada.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPESP - Fundação de Amparo a Pesquisa do Estado de São PauloGimenes, Flavia Maria de Andradeda Silva, Sila CarneiroFialho, Cleunice AuxiliadoraGomes, Marcelo BarceloBerndt, AlexandreGerdes, LucianaColozza, Maria Tereza2011-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/8625Pesquisa Agropecuaria Brasileira; v.46, n.7, jul. 2011; 751-759Pesquisa Agropecuária Brasileira; v.46, n.7, jul. 2011; 751-7591678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/8625/6423https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/8625/4357info:eu-repo/semantics/openAccess2014-06-04T16:20:50Zoai:ojs.seer.sct.embrapa.br:article/8625Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-04T16:20:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
