Resumo: This experiment was conducted to evaluate the effect of different grazing intensities on the accumulation of dry matter and morphological composition of Brachiaria brizantha cultivars. The treatment consisted of three cultivars of Brachiaria brizantha (Marandú, Xaraés and MG4) and four levels of defoliation (10, 20, 30 and 40 cm) in the period from August 2010 to July 2011. The experimental design was a randomized blocks with four replications in a 3 × 4 factorial arrangement. Cultivars showed significant behavior under different defoliation intensities as regards total dry matter and leaf accumulations, and percentage of dead material and canopy height. When subjected to different defoliation intensities, no significant effect was verified on stem accumulation, percentage of stems, forage density or leaf:stem ratio. Cultivars Marandú and Xaraés showed greater leaf accumulation, canopy height and higher leaf:stem ratio than cultivar MG4. The participation of green material in the dry matter and dry matter residue are highly influenced by defoliation intensity.

Os tratamentos consistiram em três cultivares de Brachiaria brizantha (Marandú, Xaraés e MG4) e quatro intensidades de desfolhação (10, 20, 30 e 40 cm) durante o período de agosto de 2010 a julho de 2011. O delineamento experimental foi o de blocos casualizados com quatro repetições em fatorial 3x4. As cultivares apresentaram comportamento significativo sob as diferentes intensidades de desfolhação, acúmulo de massa seca total e de folha, percentagem de material morto e altura do dossel. Quando submetido às diferentes intensidades de desfolhação não foi constatado efeito significativo para o acúmulo de colmo, percentagem de colmo, densidade da forragem e relação folha:colmo. As cultivares Marandú e Xaraés apresentaram maior acúmulo de folha, maior altura de dossel e relação folha:colmo do que o MG4. A participação de material verde na matéria seca e o resíduo de matéria seca é altamente influenciável pela intensidade de desfolha.Londrina, PRporUniversidade Estadual de LondrinaSemina: Ciências AgráriasForrageira tropicalPastagemProdutividadeRelação folhaColmoTropical foragePastureProductivity, leafStem ratioAcúmulo de massa seca em cultivares de Brachiaria brizantha submetida a intensidades de desfolhaçãoHerbage accumulation in Brachiaria brizantha cultivars submitted to defoliation intensitiesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlereponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessTEXTAcumuloMassaSeca.pdf.txtAcumuloMassaSeca.pdf.txtExtracted texttext/plain46745https://ri.ufs.br/jspui/bitstream/riufs/8501/3/AcumuloMassaSeca.pdf.txta761627b5267a9f49c446f27bd82844bMD53THUMBNAILAcumuloMassaSeca.pdf.jpgAcumuloMassaSeca.pdf.jpgGenerated Thumbnailimage/jpeg1763https://ri.ufs.br/jspui/bitstream/riufs/8501/4/AcumuloMassaSeca.pdf.jpgc84f342b6588108393af288b716de914MD54LICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/8501/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALAcumuloMassaSeca.pdfAcumuloMassaSeca.pdfapplication/pdf665819https://ri.ufs.br/jspui/bitstream/riufs/8501/2/AcumuloMassaSeca.pdf4e4464b63a2c80208ab7955a8f2c9b7cMD52riufs/85012018-06-27 09:23:17.099oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2018-06-27T12:23:17Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false
