Abstract

Given the strategic importance of commercial forest plantations of native species, this study aimed to select a tapering model to estimate the multiple products of Schizolobium parahyba var. amazonicum planting in integrated livestock-forestry systems in the Amazon and to identify the management regime with the highest production. The research was conducted in the state of Pará, comparing production as a function of variations in spacing and planting age. The Hradetzky, Schöepfer, and Max & Burkhart tapering models were evaluated, considering goodness-of-fit statistics and scatter plots. The Schöepfer model provided the most accurate estimate of tree cross-sectional volume. The management regime with 3.5 × 3.5 m spacing and 60 months promoted the highest assortment production (164 m³) and the lowest amount of residue (60 m³), indicating the largest spacing with the highest plant utilization.

Keywords
