A field experiment was conducted at Agricultural Research Station, Hukkeri, (Karnataka) to study the efficient alternate crops and cropping systems for sugarcane during 2018-20. There were 11 treatments involving different cropping systems viz., soybean - sorghum - ridge gourd (T1), pigeon pea + green gram(1:1) - beans (T2), pigeon pea + soybean(1:1) - cowpea (T3), soybean - wheat - groundnut (T4), groundnut - sorghum - sesame (T5), maize - cabbage - fallow (T6), soybean - wheat - green gram (T7), maize - wheat - sesame (T8), Bt cotton - groundnut (T9), sugarcane + onion(1:2) (T10) and sugarcane (sole) (T11) replicated thrice and laid out in randomized complete block design. The intercropping treatments were in additive series. For comparison between the crop sequences, the yield of all crops in sequences were converted into sugarcane equivalent yield on price basis. Among the cropping systems, maize-cabbage-fallow system recorded significantly higher sugarcane equivalent yield (179.08 t/ha) and total water use efficiency (199.67 kg/ha-mm) compared to rest of the cropping systems. However, sugarcane + onion intercropping recorded significantly higher (157.91 t/ha and 125.08 kg/ha-mm, respectively) compared to rest of the cropping systems and sugarcane (sole) (111.00 t/ha and 68.64 kg/ha-mm, respectively). The cropping systems involving field crops which were significantly higher over sugarcane (sole) are maize-wheat-sesame (30.65 kg/ha-mm and 117.96 t/ha, respectively), soybean-wheat-groundnut (27.40 kg/ha-mm and 120.24 t/h, respectively), soybean-wheat-green gram (23.05 kg/ha-mm and 107.55 t/ha, respectively) and Bt cotton-groundnut (17.97 kg/ha-mm and 101.71 t/ha, respectively).
