Field experiment was conducted during two consecutive Kharif seasons at Instructional Dairy Farm of G.B. Pant University of Agriculture and Technology, Pantnagar to identify inter relationship of economic traits and their association with the yield and quality of sweet sorghum under intercropping system and different nitrogen sources. Correlation has been studied in various growths, quality characters, nutrients content, uptake and yield and quality of sweet sorghum planted in a randomized block design. The linear correlation study revealed positive and highly significant association between growth parameters and stalk, juice, sugar and ethanol yield. Among the juice quality parameters, juice, brix and sucrose percent were positively and available sugar, juice purity coefficient was negatively associated with all the growth parameters and yield. Various growth parameters and nutrient content/uptake were found positively correlated with dry matter accumulation, yield of stalk, juice and calculated ethanol.
