The present study, entitled “Effect of integrated nutrient management on quality of papaya (Carica papaya L.) cv. Gujarat Junagadh Papaya 1,” was carried out for two consecutive years (2023-24 and 2024-25) at the Horticultural Research Farm, B. A. College of Agriculture, AAU, Anand, Gujarat. The experiment was laid out in a Randomized Block Design with ten treatments and three replications to evaluate the influence of inorganic fertilizers (RDF: 200:200:250 g NPK/plant), organic nutrient sources (FYM, vermicompost and castor cake) with Bio NPK liquid biofertilizer on quality attributes of papaya. Significant differences were observed among treatments for all recorded parameters. The treatment T₃ (75% RDF + 25% N from vermicompost + Bio NPK Liquid Biofertlizer) consistently outperformed others by increased maximum total soluble solids (TSS ^oBrix), reducing sugar (%), non-reducing sugar (%), total sugar (%), minimum titratable acidity (%), significantly highest β-carotene (mg/100g) and pulp thickness (cm). In contrast, the control (T₁) recorded the lowest values for quality traits, highlighting the importance of integrated nutrient application.
