The field research was conducted to evaluate the performance of quality parameters of two Isabgol cultivars for commercial production in northern dry zone of Karnataka during two years 2015-16 and 2016-17. The experiment was laid out in split plot design (SPD) with sixteen INM treatment combinations at the College of Horticulture, Bagalkot. Among the varieties the analysis on pooled data exhibited higher value in Vallabh Isabgol-1 Seed yield (12.30 q ha^-1),husk yield (3.62q ha^-1), harvest index (18.11%), test weight (2.57g), swelling factor (16.08 ccg^-1), ash content (2.43), moisture content (8.15 %) and carbohydrate (5.65%) as campared to Gujarat Isabgol-2. The higher value with INM treatments with respect to plant quality parameters Viz. were recorded, N₁₁-75 % RD of FYM (7.5 t ha^-1) + 75% RD of NPK (37.5:18.75:22.50 kg ha^-1) +Azospirillum (5kg ha^-1) + PSB (3kg ha^-1) + ZnSO₄ (15kg ha^-1) + FeSO₄ (7.5 kg ha^-1) exhibited higher seed yield (15.34 q ha^-1), husk yield (5.38 q ha^-1), harvest index (22.13%), test weight (2.57g), swelling factor (17.99 cc g^-1), ash content (2.83 %), and carbohydrate (6.69%), further minimum moisture (7.73 %) which was on par with N₁₆, N₆, N_4.Interaction effect higher quality parameters recorded in seed yield Vallabh Isabgol-1 N₁₁, 75 % RD of FYM + 75% RD of NPK +Azospirillum + PSB + ZnSO₄ + FeSO_4. exhibited seed yield (15.50 q ha^-1), husk yield (5.45 q ha^-1), harvest index (22.34 %), test weight (2.75g), swelling factor (18.23 cc g^-1), ash content (2.81%), moisture content (7.87%) and carbohydrate (6.95 %) which were all these parameters on par with V₁N₁₆, V₁N₄ and V₁N₆ and lower values quality parameters observed inV₂N₁₃.
