The experiment was carried out in twelve years old Khasi mandarin plot in Tinsukia district of Assam, India during 2005-2015 to find out the effect of integrated nutrient management (INM) on yield, quality and nutrient content of Khasi mandarin (Citrus reticulata) in acidic soil of Assam. The experiment was laid out with 5 m Í 5 m spacing along with 5 treatments, 4 replication and designed with RBD. Existing technology for application of nutrients in Khasi mandarin is split application of the recommended doses of N, P2O5 and K2O i.e., 600:300:600 g N, P2O5 and K2O/pl/yr along with 7.5 kg mustard oil cake/pl/yr in two splits. The result revealed that application of 75% RDF + VAM (500 g/plant) + PSB (100 g/plant) + Azospirillum, (100 g/plant) + T. harzianum (100 g/plant) were found effective in improving the yield, soil nutrient status and quality of Khasi mandarin with B:C ratio (4.75). The fruit obtained under this treatment was found significantly superior in quality as evident from highest juice content i.e. 48.95%; TSS i.e. 13.77%; Ascorbic acid i.e. 48.93%; total sugar, i.e. 7.47% and lowest acidity, i.e. 0.37%. The time taken for maturity was the lowest (244 days) while shelf life was the highest (18 days) though not significant. Significantly higher soil fertility status and superior N, P, K content on leaf were observed under this treatment.
