- Abstract
The study aimed to analyze the feasibility and the economic production of black wattle and charcoal in Brochier, Maratá, Paverama and Poço das Antas Rio Grande do Sul, Brazil. Subsidies were obtained with in loco questionnaires . The economic criteria used were: Net Present Value (NPV), Infinite Net Present Value (NPV inf.), Annual Equivalent Value (VAE), Expected Value of Earth (VET), Benefit Cost Ratio (B/C), internal rate of return (IRR) and average cost of production (CMPr). The average rate of attractiveness used was 6.8% p.a. The wood production data obtained was from SCHNEIDER et al. (2000). Thus, planting black acacia intercropped with maize proved to be viable, showing greater attractiveness in the 18 place index : NPV of R$ 2529,22 ha-1 VET of R$ 384.91 ha-1, VPL inf. of R$ 506.37 ha-1, TIR of 18.91% and CMPr of R$ 36.44 m-3. Charcoal production proved to be more feasible in the ovens Brochier (CMPr of R$ 0,32 m-3 and B/C of 1,94).
