The beneficial effect of intercropping of cereal (rice) and legumes (Green gram) with suitable row ratios studied under lateritic acidic soil condition of Visva-Bharati, West Bengal. Sole rice and green gram (Panna and PDM-84-139) recorded the maximum plant height, yield attributes and crop yields. Among the intercrops, rice crop sown with green gram at 2:1 row showed better performance than in other row ratios. The highest rice equivalent yield was observed at 2:1 ratio of rice+green gram cv. Panna but 1:1 ratio showed the highest benefit cost ratio. A minimum of 43.9% higher rice equivalent was observed under rice+PDM-84-139 green gram at 2:2 row ratio than rice alone. Competitive functions like relative crowding co-efficient, Land equivalent rati monetary advantage, area time equivalent ratio and relative value total were found maximum at 2:1 ratio of rice + green gram and green gram was found dominant crop in the intercropping systems.
