The paper presents the commercial cost efficiency analysis of poplar plantations, according to project evaluation indicator in agriculture and forestry - internal rate of return (IRR). The analysis was performed for planting poplar clone I-214 in the area of Ravan Srem, planting space 6x6 m, with different rotations and on different soil types. The research goal was to check the justification of funds invested in wood production in poplar plantations, based on revenues and cost analysis in different plantation ages, using the IRR. The research showed that the IRR for 12 sample plots varied in interval 4.32-6.94% with average rate of 5.63%. The internal rates are larger for plantations on good quality soil types, regarding of poplar plantation (alluvial semigleyic soil), and for shorter rotations and vice versa. The IRR values higher than 12% were not found in researched framework of cost-revenues changes rate. The sensitive analysis proved that the project is very easily affected by cost-revenues changes.
