Aims: Aim was to analyze the economic viability of an integrated crop-livestock-forest (ICLF) system area, in the municipality of Pindaré-Mirim, State of Maranhão, Brazil, using the consortium of maize (Zea mays L.), forage species Urochloa brizantha cv. Marandu and Eucalyptus (Eucalyptus urograndis).
Study Design: Case study.
Place and Duration of Study: The work was developed in a Technological Reference Unit of ICLF of Embrapa Cocais, located in the municipality of Pindaré-Mirim - Maranhão, Brazil, between January 2016 and July 2017 and The experimental area was 3 ha, divided into three subareas: Treatment I - single corn planting; Treatment II – Barreirão system; and Treatment III - Santa Fé system.
Methods: In this work, the method of operational costs was used. The following economic performance measures were calculated: Gross income (GI), Gross margin (GM), Net margin (NM), Profit, Leveling point (LP) and Rates of return (RR). The economic indicators calculated were: Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit-Cost Ratio (RBC). The data collected from the costs and revenues of each treatment were tabulated and treated with the help of Microsoft Office Excel.
Results: All the treatments presented a profit, being the Barreirão System the one that had better results, presenting P of 163 bags of maize ha-1, GI of US$ 1974, profit of US$ 780, LP in 99 bags, of 60 kg, of corn ha-1 and RR of 65.33%. Treatments I and III presented, respectively, P of 135 and 143 bags of maize ha-1, GI of US$ 1635 and US$ 1732, profit of US$ 504 and US$ 543, LP in 94 and 99 bags of corn ha-1 and RR of 44.63% and 45.67%.
Conclusion: The results obtained reinforce the importance of studying the economic feasibility of ICLF system to provide the investor with the conditions for better decision making.
