An experiment on Tomato (Lycopersicon esculentum L.) was conducted during Zaid season of 2020-21 and 2021-22, at Agriculture Research Farm, School of Agriculture Science & Technology, Sangam University, Bhilwara, Rajasthan (India) to understand the effect of integrated nutrient management at different doses combination on fruit growth, yield and quality of tomato variety Abhilash. The experiment was conducted in Randomized Block design. The nutrient sources applied were Biofertilizer [Phosphorus solubilizing bacteria (PSB) +Azotobector] @ 5kg each per ha; Vermicompost (VC) @ 10t/ha (100%); Farm Yard Manure (FYM) @ 25 t/ha (100%) and Poultry Manure (PM) @ 8 t/ha (100%). Under the present investigation 12 treatments were prepared with different combination doses of integrated nutrient management mentioned in and replicated thrice. It is clear from the results that the maximum specific gravity under the application of 75% RDF + 25% organic (FYM + VC + PM) (T₁₁) was 1.16 and 1.19 g/cm3, the T.S.S content was 5.45 and 5.67^Obrix, the ascorbic acid content was 25.53 and 25.53 mg/100g, and the acidity was 0.620% and 0.650% in both years, respectively. The lowest values for each attribute were noted when receiving control therapy. According to the results of the current experiment, T₁₁ was shown to be the optimum treatment for tomato development and yield, as measured by ascorbic acid, Total soluble solids (T.S.S.), lycopene content, specific gravity, and acidity content among other factors. The investigation's findings support the conclusion that the T₁₁ therapy is appropriate for use in tomato growing.
