A study was conducted on KVK instructional farm Sehore (M.P)during 2009-10 (Kharif) to evaluate the production potential, Land equivalent ratio, production efficiency, Relative crowding co-efficient and Economic viability of among inter cropping combination viz. Soybean, Green gram, Black gram + Maize and Pigeon pea with ratio (4:2). The grain yield was found higher 40.9 q/ha under sole Maize fallowed by sole soybean 17.6 q/ha than all inter cropping combination. But total system productivity was found highest under Soybean + Maize (4:2) combination (2720 kg/ha) followed by Soybean + Pigeon pea (4:2) 2310 kg /ha than other inter cropping combinations. Inter cropping of soybean with maize in 4:2 ratio gave maximum monetary advantage, income equivalent ratio, production efficiency and cost benefit ratio 35900, 22700, 359 and 1:2.9 respectively than other combinations. This treatment accounted maximum land equivalent ratio (1:1.4). Product of Relative crowding co-efficient K>4.2 which proved the most efficient system. Because the negative value of RCC indicates strong competitiveness of crop, while the positive value of RCC indicates, weak competitiveness of crop. Thus maize and pigeon pea crop was found dominant companion to intercrop of soybean along with enhanced economic viability and sustainable productivity in Sehore district of Madhya Pradesh.
