| We assessed the damage done by cattle in three species of trees in a silvopastoral system implanted in the subtropical region of Brazil. The species Schinus terebinthifolius (Raddi), Grevillea robusta (A. Cunn. Ex R. Br) and Eucalyptus dunnii (Maiden), were planted in single rows (14 m x 3 m) to compose a silvopastoral system. During the first three years, the area was used for grain production in alley cropping systems. After 41 months of planting trees cattle were first introduced in the area. Five classes of damage intensity were established: no damage, low, medium, high, and extreme. The damage to the bark of trees were larger than those caused to the crown. The trees of S. terebinthifolius were more damaged by cattle. The maintenance of S.... |

| The effects of cutting plant age (21, 28, 35, 42, 49, 56, 63 and 70 days) on dry matter (DM) yield, and morphogenetic and structural characteristics of Axonopus aureus, during rainy season, were evaluated under natural field conditions. The experimental design was a completely randomized, with three replications. Evaluations were carried out during the period of June to August 2009. DM yield, absolute growth rate (AGR), number of tillers plant-1, number of leafs plant-1, leaf area, leaf senescence and elongation rates and blade length increased consistently with growth stage. The relations between DM yield and AGR with cutting plants age were described by the quadratic regression model. The maximum DM yield and forage production rate performance were... |
