This paper discusses EMBRAPA'S agroforestry systems experience in the Brasilia Amazon. The forestry species and fruit tress introduced in shifting systems had great success, particularly the wood-producing species Cordia goeldiana and Swietenia macrophylla and fruit trees Musa spp. and Theobroma grandiflorum. In forestry plantations, Vigna unguiculata was mixed with the trees C. goeldiana, Jacaranda copaia and Bagassa guianensis in the first two years to reduce cost of investment and cultural treatment. In this case, Vigna unguiculata did not affect survival of trees and increased tree height and diameter growth. The introduction of wood-producing trees in livestock pastures can represent formation of a system more balanced and stable through nutrient cycling than is possible today. A silvopastorial system has been carrid out in the Paragominas regional (Pará) using the forestry species Eucalyptus tereticornis, B. guianensis and Schizolobium amazonicum, the crop Zea mays and forage species Brachiaria brizantha, B. humidicola and Panicum maximum. Performance of the forestry and forage species has been satisfactory and the corn yield was more than the rebional average. The cattle, at a low stocking rate, graze on the site and cause no harm to the plantet trees.
