Studies on chilli based intercropping systems were carried out using six intercrops at Department of Horticulture, College of Agriculture, Raichur  of University of Agricultural Sciences, Dharwad. The study was conducted to know the effect of different intercrops viz., radish, carrot, onion, garlic, cluster bean and dolichos bean on chilli. Significantly the highest (75.16 q/ha) yields were obtained in sole chilli. Yield of chilli varied with different intercropping systems. Radish + chilli intercropping system results in realization of significantly the highest (72.05 q/ha) yield in chilli followed by chilli + carrot (70.77 q/ha).  On the contrary 'chilli + cluster bean' resulted in lower yield of 64.43 q/ha. Further, economic analysis was also carried out. The highest net returns (Rs. 59,261/ha) and B:C ratio (1.75) were obtained in chilli, which was intercroped with garlic. On the contrary, the lowest net returns (Rs. 12744 and B:C ratio (1.01) were obtained in sole chilli. This obviously reflected the importance of intercropping to increase the productivity per unit area. Further, it also offer insurance against crop failure.
