The field experiment was conducted to evaluate the performance of two Isabgol cultivars and INM on the incidence of aphids in northern dry zone of Karnataka during 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. Pooled data analysis of two years data exhibited lower aphid (Aphis gossypii Glover) incidence in Vallabha Isabgol-1 with integrated nutrient management. The lower aphid incidence was recorded with supply of 75 % RD of FYM + 75 % RD of NPK + Azospirillum + PSB + ZnSO4 + FeSO4 (N11) and maximum aphid incidence was recorded with supply of 50 % RD of FYM + 50 % RD of NPK + Azotobacter (N13) at 90 DAS. In interaction effect minimum aphid infestation was recorded in Vallabh Isabgol-1, supplied with Vermicompost + 50 % RD of NPK + Azospirillum + Azotobacter (V1N6) followed by Vallabh Isabgol-1, 75 % RD of FYM + 75 % RD of NPK + Azospirillum + PSB + ZnSO4 + FeSO4 (V1N11) as compared to other treatment. The maximum aphid incidence was recorded in Gujarat Isabgol-2, supplied with RD of FYM + RD of NPK (V2N1).
