SUMMARY:

The Brazilian agricultural sector has undergone significant transformations from an increase in production costs and a more competitive market that requires increased production, quality, and profitability. The crop integration system-livestock-forest is an alternative to optimize land use while promoting soil conservation. In the Amazon, forest plantations of native and exotic species with livestock have been combined. Still, it is necessary to investigate whether the quality and productivity of the plantations are affected. Therefore, this work aims to quantify the wood stock and estimate the yield on paricá laminated wood for veneering in cattle-associated plantations in the southeastern Brazilian Amazon from tapering functions. The plantations are located on the Cinco Águas farm in Abel Figueiredo, Pará, Brazil. The plantations range in age between four and three years, presence or not of cattle, type of fertilization, and spacings 3.5 x 3.5 and 4.0 x 2.0, occupying 25 there each. The forest inventory will be carried out using circular plots of size 0.0245 ha with 20 trees, collecting data from CAPs, height, and volume of the trees by cubing with the aid of Criterion RD 1000. Hypsometric and dendrometric equations will be adjusted from classic linear and nonlinear models. First, the stems of the trees will be analyzed, taking into account the planting characteristics, and the cubed volume will be calculated by Smalian and, later, the volume stock by assortments. Then, the volume for veneering will be estimated considering different crop conditions. This study is expected to quantify and describe the veneering yield in the other plantations of Paricá as well as whether the presence of cattle can affect the species' stem quality and veneering stock.
