Abstract: An experiment was conducted to study the effect of cultivars and organic nutrient management on quality of liquid Jaggery at Agriculture Research Station, Kumta, Uttara Kannada, Karnataka. The experiment consisted three main plots (Cultivars) viz., C₁: SNK 635, C₂: Co 86032 and C₃: Konanakatte and seven sub plots (nutrient management practices) viz., N₁: Farm Yard Manure (FYM) (1/3^rd) + Vermicompost (VC) (1/3^rd) + Biogas slurry (BGS)(1/3^rd), N₂: FYM (1/3^rd) + VC (1/3^rd) + Biodigester filtrate (BDF) (1/3^rd), N₃: FYM (50%) + VC (50%), N₄: FYM (50%) + BGS (50%), N₅: FYM (50%) + BDF (50%), N₆: Recommended package of practices (RPP) and N₇: Farmer’s practice. The results indicated that, non- reducing sugar % was not significantly influenced by cultivars and nutrient management and their interactions. Whereas, reducing sugar content was significantly influenced by cultivars and nutrient management. The cultivar SNK 635 recorded significantly lower reducing sugars (13.16%). Other quality parameters like fat, protein, ash, moisture, colour and pH of liquid Jaggery were not significantly influenced by cultivars and organic treatments. EC values of liquid Jaggery was significantly influenced by cultivars. SNK 635 recorded significantly lower EC values (1.11 dSm^-1). Overall acceptability score point of SNK 635 liquid Jaggery was 8.25. Organic nutrient management had significantly higher overall acceptability score points.
