Abstract: Field experiment was conducted to study the response of two sugarcane cultivars (SNK 09211 (C₁) and SNK 07680 (C₂) to different organic nutrient management practices [N₁: 100% organics through farmyard (FYM), vermicompost (VC), in situ green manuring of Dhaincha (IGM) equivalent to RDN, N₂: 100% organics through FYM, VC, biodigetser filtrate (BDF) 1/3^rd each equivalent to RDN, N₃: 100% organics through FYM and BDF (50% each) equivalent to RDN, N₄: 100% organics through FYM and VC (50% each) equivalent to RDN, N₅: Farmers practice and N₆: Recommended package of practices (RPP)] with special reference to jaggery production and quality during 2017-18 at permanent organic site at ARS, Sankeshwar. The results revealed that, SNK 07680 recorded significantly higher cane weight, No. of millable cane and cane yield (128 t ha^-1) compared to C₁. Cultivar SNK 07680 also recorded significantly higher sugar yield over SNK 09211. Quality parameters of sugarcane did not differed significantly among cultivars, NMPs and their combined effects. Among the nutrient management practices (NMPs), RPP recorded higher number of millable cane and cane yield (131 t ha^-1) compared other NMPs. Among the organic treatments 100% organics through FYM, VC and IGM equivalent to RDN recorded significantly higher cane (126 t ha^-1) and sugar yield (17.30 t ha^-1) over organic treatments. N₁ recorded significantly higher gross and net returns (Rs.3,78,300, and 2,38,550 ha^-1) over rest of the treatments. While, BC ratio was higher (3.19) with N₃ than other treatments.
