Crescimento inicial de eucalipto e acácia, em diferentes arranjos de integração lavoura-pecuária-floresta

Abstract

The objective was to evaluate initial growth of clonal Eucalyptus, hybrid Eucalyptus grandis x E. urophylla and Acacia (Acacia mangium) trees in alternate and not alternate rows of trees, intercropped with forage (crop-livestock-forest integration - CLFI) and monoculture. The design was a randomized complete block design with four replications, three arboreal arrangements consisting of eucalyptus, acacia + eucalyptus, acacia, all planted in crop-livestock-forest integration and two monoculture controls (Eucalyptus and Acacia). The height of eucalyptus trees is influenced by the consortium with Acacia in the studied CLFI designs, which does not happen with the diameter at breast height. The arrangement of species of eucalyptus and acacia intercropping in the same row planting has productivity equal to the array using only the lines of eucalyptus planting systems . Timber productivity of acacia and eucalyptus in the same row is less than the same species line, however, the sum of the timber produced from the two species is greater than the arrangement of eucalyptus only row in CLFI.
