Abstract: A field experiment was conducted during autumnseason of 2017-18 at Instructional-cum-research farm RMD CARS, Ambikapur to evaluate the most profitable crops grown as intercrops with winter planted sugarcane under thirteen treatments formulated with intercropping i.e. sugarcane sole, sugarcane + onion (1:3), sugarcane + onion (1:4), sugarcane + potato (1:1), sugarcane + potato (1:2) , sugarcane + sweetcorn (1:1), sugarcane + sweetcorn (1:2), sugarcane + wheat (1:2), sugarcane + wheat (1:3), sugarcane + frenchbean (1:2), sugarcane + frenchbean (1:3), sugarcane + mustard (1:1) and sugarcane + mustard (1:2) in randomized block design. Based on the one year study, onion (1:3) intercropping was selected as most remunerative in autumn/winter cane with the highest no. of millable cane (93.69 x 103 ha-1), millable cane length (309.26 cm), cane weight (2.72 kg cane-1), cane yield (255.41 t ha-1), cane equivalent yield (295.95 t ha-1) and net return and B:C ratio (Rs. 799244 ha-1 and 9.08) among all the intercropping systems. Sugarcane + onion (1:4) and sugarcane + potato (1:1) intercropping were also found comparable with sugarcane + onion (1:3). Whereas, lowest no. of millable cane (44.55 x 103 ha-1), millable cane length (258.33 cm), cane weight (1.61 kg cane-1), cane yield (71.79 t ha-1), cane equivalent yield (89.58 t ha-1) and net return and B:C ratio (Rs. 189227 ha-1and 2.38 ) recorded under sugarcane + wheat (1:3) intercropping system among the intercrops.
