Hence, an experiment as split plot design carried out in 2008 at Kermanshah region, aim to economic evaluation of medicinal pumpkin intercropped with both chickpea and lentil. Main plots included nitrogen fertilizer (0, 75, 100, 125, Kg.ha-1) and sub plot were three cropping systems consisting of sole cropping of medicinal pumpkin and intercropped with four rows of lentil and chickpea. The highest LER (2.20) and cost benefit ratio (8.81) were obtained from medicinal pumpkin intercropped with lentil at 75 Kg.N/ha and medicinal pumpkin intercropped with chickpea at 125 Kg.N/ha, respectively. All of indices showed profitability of medicinal pumpkin intercropped both with lentil and chickpea in Kermanshah region. There were the highest land productivity and economic profitability by intercropping the medicinal pumpkin and lentil with 75 Kg.N/ha consumption.
