The silvicultural and economic potential of paricá (Schizolobium amazonicum) has encouraged the expansion of this crop, mainly in the northern region of the country, provoking the need for studies on the species. The objective of this study was to estimate paricá production in Paragominas region, Para State, Brazil, at 5, 6 and 7 years, in three classes of productivity considering five plant arrangements, being identified the main costs of production, in addition to those most affected by plant arrangements. The volumetric estimation was obtained by modeling in population level and the analysis of the costs, through the methodology of the operational cost. It was possible to infer that the arrangement of plants 3 m x 2 m was superior in volume, compared to the other analyzed plant arrangements. The effective operating cost represented on average 65% of the total production costs. Transport was the most significant individual cost, in all analyzed plant arrangements. The maintenance, among the set of activities, was the most significant in planting, fact that may be related to the number and the long period for the activities execution. Smaller plant arrangements presented the higher total costs of production, depending or not on the remuneration for the use of the permanent and current capital.Downloads
