An experiment was carried out in the Department of Horticulture, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India, during 2015-16 and 2016-17 to study the influence of integrated nutrient management on growth, yield and quality parameters of papaya (Carica papaya L.). For this plant of Sapna cultivar was planted on 20th March during both years of experimentation at a spacing of 2.0 x 2.0 m. There were eighteen treatments comprising Azotobacter, PSB and vermicompost with graded dose of RDF including one control, replicated thrice in randomized block design. All treatments were applied at the time of planting in the field. The data of both the years of experiment were analyzed which clearly shows that during both years of experimentation significantly lesser number of nodes and days taken to first flowering, fruit developmental period with reduced fruit drop and maximum fruit retention with higher fruit yield, fruit weight and volume were recorded in the plants which were fertilized with RDF 75% + Azotobacter 100 g + PSB 100 g + vermicompost 2 kg/plant, whereas uninoculated plants results in higher number of nodes to first flowering along with more days taken for the appearance of first flower, took maximum fruit developmental period, results maximum fruit drop percent and minimum fruit retention percent along with minimum yield of fruits which are lighter in weight and volume during both years of experimentation. As quality characters of fruits are concerned fruits having maximum pulp percent, total soluble solids (TSS) and total sugar contents and minimum peel percent, titratable acidity contents were recorded in fruits which were produced from the plants fertilized with RDF 75% + Azotobacter 100 g + PSB 100 g + vermicompost 2 kg/plant, whereas uninoculated plants results in minimum pulp percent, total soluble solids (TSS) and total sugar contents and maximum peel percent, higher titratable acidity contents during both years of experimentation.
