An experiment was conducted to know the influence of growth regulators, chemicals and biofertilizers on germination, seedling growth and vigour attributes of aonla. The growth regulators (GA3 and NAA) chemicals (KNO3) and biofertilizers (Azospirillum, Azotobactor, PSB and VAM) were used as treatments at different concentrations. The seeds pre-soaked with GA3 200 ppm solution recorded the earliest germination (8.33 days), highest germination percentage (88.88 %), faster rate of germination (1.07), maximum seedling height (28.47 cm), seedling stem girth (1.26 cm), seedling biomass (2.28 g) and highest vigour index of seedlings (202.6) compare to other treatments. In conclusion, soaking of aonla seeds in GA3 200 ppm solution for 12 hours followed by 12 hours shade drying will improves the seed germination characters and seedling attributes.
