| The Panicum maximum breeding program coordinated by the Brazilian Agricultural Research Corporation (Embrapa) has been evaluating and selecting genotypes under different soil and climatic conditions, with the objective to release new cultivars adapted to the diverse regions of Brazil. For the Amazon biome, small-plot experiments carried out in Acre between 2003 and 2005 allowed the selection of some promising genotypes (Valentim and Andrade 2005; Valentim et al. 2006; Andrade and Valentim 2009), with higher potential for forage growth than cultivars on the market. The objec-tive of this work was to compare 2 new P. maximum genotypes with cv. Tanzânia in relation to carrying ca-pacity and animal performance, when managed under rotational stocking in the... |

| Dynamic global vegetation models (DGVMs) simulate surface processes such as the transfer of energy, water, CO2, and momentum between the terrestrial surface and the atmosphere, biogeochemical cycles, carbon assimilation by vegetation, phenology, and land use change in scenarios of varying atmospheric CO2 concentrations. DGVMs increase the complexity and the Earth system representation when they are coupled with atmospheric global circulation models (AGCMs) or climate models. However, plant physiological processes are still a major source of uncertainty in DGVMs. The maximum velocity of carboxylation (Vcmax), for example, has a direct impact over productivity in the models. This parameter is often underestimated or imprecisely defined for the various plant... |

| Brachiaria humidicola is a perennial and stoloniferous forage grass, with excellent adaptation to infertile soils and waterlogging. Producers in northern Brazil have become interested in this species, especially after the degradation of large areas of lowly permeable soils sown with B. brizantha cv. Marandu, which is highly intoler-ant of soil waterlogging (Andrade and Valentim 2006). However, since only 3 cultivars of B. humidicola are registered in Brazil (Mapa 2013), there is a need to de-velop new cultivars adapted to the range of environ-mental conditions experienced. Recently, Embrapa Beef Cattle obtained intraspecific hybrids of B. humidicola that need to be evaluated agronomically, aiming at sub-sequent grazing trials and future releases. The... |

| A pecuária bovina, especialmente a criação de gado de corte, é a atividade do setor primário com maior importância econômica no Estado do Acre. Atualmente, o estado possui o quarto maior rebanho bovino da Região Norte, estimado em cerca de 2,6 milhões de cabeças, criado em uma área de aproximadamente 1,4 milhão de hectares de pastagens cultivadas. Assim como no restante da Região Amazônica, no Estado do Acre as pastagens cultivadas representam a base de sustentação da atividade pecuária, fornecendo forragem de qualidade e em quantidade suficiente para a alimentação do rebanho. Entretanto, nos últimos 10 anos, a pecuária bovina no Acre vem sofrendo com o problema da degradação das pastagens cultivadas, causada principalmente pela síndrome da morte do... |

| The biochemical methane potential (BMP) index from agricultural, agroindustrial and livestock wastes it is essential for bioreactor?s design and to enable the biogas plants. For BMP standard procedure is necessary to use an inoculum stable, acclimated to the test conditions and adapted to the substrate. In general, inoculum seed from co-digestion biogas plant is used, but this is not practicable in countries like Brazil. This work reports a laboratory case study to produce and maintain a mesophilic anaerobic inoculum for BMP test according VDI 4630. This manuscript suggests a mesophilic acclimation methodology of a mixture made with different inoculum seeds (fresh dairy manure, UASB sludge from swine manure treatment and UASB sludge from food industry).... |
