| In order to study the influence of mineral nutrition on quality and the growth of seedlings of Schinus terebinthifolius Raddi, Mimosa scabrella Benth. and Allophylus edulis (ST. Hil.) Radl, a experiment was conducted in the nursery facilities of Embrapa Florestas, Colombo – PR. The three species were sown in plastic containers of 50 cm3 in February 2004. The substrate was a mixture of a commercial formula (pine bark and vermiculite) and granulated coconut fiber in a proportion of 70% and 30% respectively. The treatments were three different dosages of mineral fertilizers, which were divided in two applications, base fertilizaton (mixed to the substrate) and covering. A completely randomized design was used, with 7 repetitions and 9 seedlings per plot.... |

| The woodwasp Sirex noctilio Fabricius (Hymenoptera: Siricidae) was introduced in Brazil in 1988 and became the main pest in pine plantations. It has spread to about 1.000.000 ha, at different population levels, in the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo and Minas Gerais. Control is done mainly by using a nematode, Deladenus siricidicola Bedding (Nematoda: Neothylenchidae). The evaluation of the efficiency of natural enemies has been difficult because there are no appropriate sampling systems. This study tested a hierarchical sampling system to define the sample size to monitor the S. noctilio population and the efficiency of their natural enemies, which was found to be perfectly adequate. |

| O presente trabalho teve por objetivos estimar a produção de madeira, o estoque de carbono e a rentabilidade econômica, incluindo a venda de créditos de carbono de plantações de Eucalyptus grandis e Pinus elliottii em consórcio com pastagens. Foram utilizados dois experimentos com cada espécie, todos instalados em Alegrete, RS, em áreas de pastagem natural. Os experimentos possuíam três tratamentos, dois deles constituídos por sistemas silvipastoris implantados em fileiras triplas de árvores, com ambas as espécies no espaçamento de 3,0 m x 1,5 m, sendo o primeiro com um corredor de 14 m, entre as fileiras triplas, destinado ao pastejo dos animais, e o outro com um corredor de 34 m. O terceiro tratamento possuía o cultivo isolado das duas espécies... |

| 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.... |
