Afield experiment was carried out atAgricultural Research Station, Hukkeri (Dist. Belagavi) during 2019-20 to study the productivity and economics seasonal sugarcane based intercropping systems. The experiment was laid out in split-split plot design with three farming practices in main plot such as M_1-: recommended package of practices (RPP), M_2-: organic farming (OF) and M^3-: natural farming (NF); in sub plots two spacings viz., S_1-: 60-180-60 cm × 60 cm (paired row planting) and S_2-: 240 cm × 60 cm (wide row planting) and in sub-sub plots three intercropping systems were taken viz., I_1-: sugarcane + onion fb turmeric, I^2-: sugarcane + onion + cowpea + coriander + green chilli and I^3-: sole sugarcane. Results revealed that, RPP recorded a significantly higher NMC (73.04 thousand ha^-1), cane yield (93.8 t ha^-1) and net returns ( 244855 ha^-1) than organic farming and natural farming practices. Between two spacings, paired row planting recorded significantly higher NMC (83.77 thousand ha^-1), cane yield (100.9 t ha^-1) and net returns ( 214718 ha^-1) than wide row planting. Among the intercropping systems, sugarcane + onion fb turmeric recorded significantly higher sugarcane equivalent yield (170.3 t ha^-1) and net returns ( 277556 ha^-1) than other intercropping systems.
