Resumo: The aim of this study was to evaluate CO2 emission, canopy characteristics and herbage accumulation in pastures of pensacola bahiagrass under frequencies of defoliation. The experiment was conducted at the Universidade Estadual Paulista "Julio de Mesquita Filho", Faculty of Agrarian Sciences and Veterinary of UNESP, Jaboticabal, São Paulo, Brasil. The experimental period was from May 3rd to July 26th 2012. The experimental area comprised 28 m2 of pensacola bahiagrass (Paspalum notatum Flügge), divided into 10 plots for allocation of treatment (frequencies of defoliation = 2 or 4 weeks). The following variables were studied: canopy height, light interception, leaf area index, herbage accumulation, tiller density, CO2 emissions, soil temperature and moisture. The frequencies of defoliation in the months of May, June and July slightly affect pensacola bahiagrass characteristics. CO2, soil temperature and moisture are more associated to environmental conditions (months of evaluation) than to the frequencies of defoliation imposed to the canopies.KEYWORDS: greenhouse gas; Paspalum notatum Flügge; sward modifications.

O experimento foi conduzido na Universidade Estadual Paulista “Júlio de Mesquita Filho”, Faculdade de Ciências Agrárias e Veterinárias da UNESP, Câmpus de Jaboticabal. O período experimental foi de 03 de maio a 26 de julho de 2012. A área experimental foi de 28 m2, de capim-pensacola (Paspalum notatum Flügge), dividida em 10 parcelas para alocação dos tratamentos (frequências de desfolhação = 2 ou 4 semanas). As variáveis avaliadas foram: altura do dossel, interceptação de luz, índice de área foliar, acúmulo de forragem, densidade populacional de perfilhos, emissão de CO2, temperatura e umidade do solo. As frequências de desfolhação nos meses de maio, junho e julho, pouco afetam as características do capim-pensacola. A umidade do solo, temperatura e emissão de CO2 estão mais associadas às condições ambientais e, portanto, meses de avaliação do que às frequências de desfolhação impostas aos dosséis.PALAVRAS-CHAVE: gás de efeito estufa; modifições no dossel; Paspalum notatum Flügge.  Universidade Federal de Goiás2014-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/2068810.5216/cab.v15i2.20688Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 15 No. 2 (2014); 138-144Ciência Animal Brasileira / Brazilian Animal Science; v. 15 n. 2 (2014); 138-1441809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/20688/16705https://revistas.ufg.br/vet/article/view/20688/16706Galzerano, LeandroMalheiros, Euclides BragaMorgado, Eliane da SilvaRuggieri, Ana Claudiainfo:eu-repo/semantics/openAccess2014-06-30T13:37:48Zoai:ojs.revistas.ufg.br:article/20688Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:55.975688Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
