An intercropping experiment on chili and garlic was conducted during rabi season of 2007-08 at the Bangladesh Agricultural Research Institute Farm, Joydebpur, Gazipur to find out suitable intercrop combination for higher profitability and economic return. Sole garlic, sole chili and four intercrop combinations (66, 53, 33 and 26% chili combined with cent percent garlic) were evaluated in the present study. Significantly the highest garlic (6.31 t/ha) and chili yield (8.50 t/ha) were obtained from their respective sole crops. Garlic yield was reduced (6-16%) due to intercropping, but it was compensated by the chili yield. Moreover, land equivalent ratios (LER) of the intercrop treatments were higher than those of sole crops. The highest (8.2 t/ha) garlic equivalent yield (GEY) was obtained from 100% garlic + 53% chili. This treatment also gave the highest LER (1.78), gross return (Tk 492000/ha), net return (Tk. 417470/ha) and benefit cost ratio (6.60).
