A field experiment was carried out to evaluate the response of organic manures (FYM, Vermicompost), inorganic fertilizers (NPK), biofertilizers (Azotobacter and PSB) on flowering, fruit yield and quality of mango cv. Amrapali under high density orcharding. The maximum Plant height (396.67 and 416.92 cm), Plant spread (311.67 and 337.67 cm), number of panicles per plant (98.00 and 240.00), was recorded with the application of T14 75 % RDF + 40 kg Vermicompost + 250g Azotobacter + 250g PSB /plant, closely followed by T13 75%RDF + 20 kg Vermicompost + 250g Azotobacter + 250g PSB/plant and fruit set ( 30.90 and 30.03%), fruit yield (22.72 and 23.36 kg/tree), fruit yield (363.47 and 373.81 q/ha) and physic-chemical parameters viz., maximum fruit length (9.62 and 9.70 cm), width ( 6.22 and 6.39 cm), weight (192.97 and 183.67 g) was recorded with the application of T13 75 % RDF + 20 kg Vermicompost + 250g Azotobacter + 250g PSB /plant closely followed by T14 75%RDF + 40 kg Vermicompost + 250g Azotobacter + 250g PSB/plant. However, the chemical composition of fruit viz., maximum TSS ( 20.24 and 21.43 0Brix), reducing sugars (8.10 and 8.24%), non reducing sugar (9.65 and 9.94%), total sugar (17.75 and 18.18%) and minimum acidity content (0.124 and 0.121 %) were recorded with the application of T13 75 % RDF + 20 kg Vermicompost + 250g Azotobacter + 250g PSB /plant closely followed by T14 75%RDF + 40 kg Vermicompost + 250g Azotobacter + 250g PSB/plant.
