An agroforestry system comprising of Poplar (Populus deltoides clone AY-48), wheat and fodder maize crops was designed, in order to compare the economics of agroforestry system with conventional agricultural system. Poplar (Populus deltoides clone AY-48) was planted at a density of 455trees/ha, 305trees/ha, and 230trees/ha at the spacing of 3.66 x 6.10m (D1), 3.66 x 9.10m (D2) and 3.66 x 12.10m (D3) respectively. Agricultural crops namely, wheat (Triticum aestivum) variety Ingalab-91 and fodder maize (Zea mays) variety Neelum were sown alternately during "Rabi" and "Kharif" seasons each year throughout the entire study periods in poplar plots. To compare the differences between sole crop and intercropping the wheat and fodder-maize were also sown in separate plots (Dw/f). Highest net benefits (51495 Rs./ha) was observed in the treatment D2 while lowest net benefits (10904 Rs./ha) was observed in sole wheat, fodder maize treatment (Dw). The highest BCR (1.10) was recorded in treatment D2 and lowest BCR (0.65) was observed for sole poplar tree planting in treatment D4. The highest IRR was also (21.91 %) observed in treatment D2 and lowest (0.78%) for treatment D4. In the dominance analysis it was that Treatment D4, D1 and D5 were dominated. The net benefit curve showed that net benefits were highest in treatment D2 while lowest in treatment D1 with the increase in cost. The marginal rate of return was highest in treatment D2 and lowest in treatment Dw. It wa
s observed in the sensitivity analysis that if the future input prices increased by10% or the future output prices decreased by 10% even then it was economical to recommend the treatment D2 and D3.
