Abstract: A field experiment was conducted at sugarcane research farm, Zadshyapur of S. Nijalingappa Sugar Institute (SNSI) of Belagavi which lies in northern transition zone of Karnataka (Zone-8) during 2017. The experiment was laid out in split plot design with four controls outside the experiment replicated thrice. The treatments included three row spacing as main plots (150 cm, 180 cm and 210 cm), inter cropping with sugarbeet, sweet sorghum and sweet potato with 1:1 and 1:2 ratio as sub-plots with four control plots (sole sugarcane (90 cm), sole sugarbeet, sole sweet sorghum and sole sweet potato) outside the experiment. On the basis of results obtained from present investigation, intercropping of sugarcane (150 cm) + sugarbeet 1:2 row proportion realised significantly higher net returns (₹ 2, 30, 211 ha ^-1).Sugarcane (180 cm) + sweet sorghum 1:2 row proportion recorded significantly higher B:C (3.12) and found at par with sugarcane (150 cm) + sweet sorghum 1:2 row (3.12). Sugarcane (150 cm) + sweet potato with 1:2 row proportion recorded significantly higher LER (1.46). Sugarcane (150 cm) + Sugarbeet with 1:2 row proportion recorded significantly higher ATER (1.17). Significantly higher competition ratio (4.66) in sugarcane was recorded by sugarcane (210 cm) + sugarbeet with 1:1 row proportion.
