| Os objetivos deste trabalho foram avaliar os efeitos de árvores dispostas em renques sobre as características produtivas e nutricionais de Urochloa decumbens e identificar a distância média, na qual ocorre o melhor aproveitamento do sombreamento moderado, em um sistema agrossilvipastoril. Os tratamentos consistiram em distâncias dos pontos de observação ao renque das árvores (0, 3, 6, 9, 12 e 15 m) e foram distribuídos em blocos ao acaso, com quatro repetições. A densidade de perfilhos e a massa e a taxa de acúmulo de forragem e a composição química do pasto foram avaliadas. A densidade de perfilhos, a massa e a taxa de acúmulo de forragem aumentaram com a distância do renque, com valores máximos de 392 perfilhos m-2, 1.347 kg ha-1 e 30,1 kg ha-1 por dia,... |

| Shade in silvopastoral systems improves the thermal comfort of animals, but it may also affect the pasture productivity and can contribute to soil compaction in the shaded areas due to the increase in the number of animals looking for comfort. The effect of grazing at various distances from tree rows (under the tree canopy, at 6 and at 12 m away from the trees) on the soil bulk density and on the aerial and root biomass of Brachiaria decumbens was evaluated in both the dry and the rainy seasons. The study was carried out on an Orthic Ferralsol in a randomized block design with two replications. Tree rows were composed of Eucalyptus grandis and Acacia mangium species, and the paddocks were submitted to a rotational stocking management, using Holstein (Bos... |

| It was studied the effects of shading (0, 36 and 54%) and of four nitrogen doses (0, 50, 100 and 150 mg N/dm³ of soil) on the morphogenetic traits and on the tillering of grasses of Brachiaria genus (B. decumbens, B. ruziziensis and B. brizantha cv. Marandu and cv. Xaraes), cultivated in pots with 5 kg substrate. It was used a complete random design, in a 3 × 4 × 4 factorial scheme with three replications. Nitrogen promoted increase in leaf appearance rate and in average leaf blade length, whereas shading increased stem elongation rate. Leaf elongation rate and tillering varied with the interaction among shading percentages and nitrogen doses. Shading increased response efficiency of leaf elongation rate to nitrogen doses, but reduced for tillering,... |
