RESUMO:
The knowledge about and productive potential of forest species should contribute significantly as basis for the proposition of action sthat allow a correct restoration or conservation. Contributing to an appropriate planning of the exploitation of particular area and conservation of ecosystems, which contributes to a sustainable production of their products. This study aimed to evaluate growth, production biomass distribution of three acácia (Acacia mangiumWilld), neem (Azadirachta indica A. Juss) and sabiá (Mimosa caesalpiniae folia Benth) the 3 and 4 years of age, in response an two farming methods. The experimental design was a randomized block factorial two treatments, less intensive and more intensive, and four repetitions, total in eight installments. Being the eight parcels of 576 m ² (24 x 24), with spacing between plants of 3x3 m, being 64 plants/plotand useful portion of 36 plants. In the treatment with more intensive cultivation was used bovine manure (4.0 t/ha), super triple (146.0 kg/ha) distributed in furrow sand calcareous (2.0 t/ha) and NPK (6-30 -6:100 g/plant), in pits side. All treatment more intensive was applied NPK (6-30 -6:100 g/plant), in pits side. The growth feach tree was obtained by measuring the height (m) and diameter (cm). From these data were calculated the basal area (m2/ha), cylindrical volume (m3/ha), actual volume (m3/ha) and stacked volume (st/ha). To obtain the of the aerial part biomass average tree was felled, and its components (leaves, twigs, barkandwood) separated, weighed and dried, yielding fresh and dry biomass. Inall the studied variables showed different behaviors, where treatment more intensive had greater influence in thegrowth, production and amount of biomass. The soil preparation, in the line of planting, along with the fertilizer foundation, positively influences growth and volume production of species acácia, nem and sabiá. Emphasizing as well the importance of appropriate soil management for the initial growth of the three species.
