The study was conducted to investigate the effect of organic manures and biofertilizers on the vegetative growth, fruit quality and leaf nutrient status of guava. The treatments consisted of the application of vermicompost, Azotobacter, Azospirillum, phosphorous solubilising bacteria (PSB) and farmyard manure (FYM) in different doses and combinations along with a control in which only inorganic fertilizers were applied. Combined application of vermicompost (30 kg/Plant) + Azospirillum @ 250 g/tree + PSB @250 g/tree resulted in maximum plant height, canopy spread, trunk girth, fruit weight, TSS, total sugars and vitamin C while maintaining yield at par with inorganic fertilizers treatment. Maximum leaf P and K content was recorded in treatment consisting of vermicompost (30 kg/plant) + Azospirillum @ 150 g/tree + PSB @150 g/tree but maximum leaf N content was recorded under FYM (30 kg/plant) + Azospirillum @ 250 g/tree + PSB @250 g/tree. Use of biofertilizers with organic manures was found to be a good approach for production of quality guava fruits without compromising the yield.
