A field experiment was conducted at Horticulture Research Centre, Chauras Campus, HNB, University, Garhwal, Uttarakhand during Rabi season to find out the effect of integrated nutrients on growth, yield and quality of tomato (Lycopersion esculantum Mill.) Cv. Punjab Chhuhara. The experiment was laid out in randomized block design with three replications. The experiment consist of twelve treatments viz., NPK 100% (T1 ), NPK 50% (T2 ), F.Y.M (T3 ), Vermicompost (T4 ), Azotobactor (T5 ), NPK 100% + F.Y.M (T6 ), NPK 100% + Vermicompost (T7 ), NPK 100% + Azotobactor (T8 ), NPK 50% + F.Y.M (T9 ), NPK 50% + Vermicompost (T10 ), NPK50% + Azotobactor (T11 ) with Control (T12 ). Results were found to be significant for all the growth, yield and quality characters under combined use of organic, inorganic and biofertilizer. Plant height (83.12 cm), leaf area (219.12 cm2), branch/plant (8.23), leaf/branch (18.59), cluster/plant (13.83), fruit/cluster (4.36), T.S.S (5.82 °Brix) and ascorbic acid (28.16 mg/100g) were maximum in T8 (NPK 100% + Azotobactor), while minimum in T12 (Control). Whereas, fruit size (6.38 cm), fruit weight (119.32 g), fruit yield/plant (1.83 kg), yield/ha (285 q) were highest in T7 (NPK 100% + Vermicompost), while minimum in T12 (Control). The results clearly indicated that T7 (NPK 100% + Vermicompost) and T8 (NPK 100% + Azotobactor) is most effective to improve the growth, yield and quality of tomato compression to other treatments.
