The present investigation entitled “Effect of pre-sowing seed treatments for enhancing the germination and seedling growth in aonla (Emblica officinalis Gaertn.) was conducted at College of Horticulture, Dapoli. Dist. Ratnagiri (M.S.) academic year 2024-25. The experiment comprised of ten different pre-sowing seed treatments including GA3 at concentrations 250 ppm, 500 ppm, 750 ppm for 12 hrs; KNO3 at 0.5%, 1.0%, 1.5% levels for 12 hrs; Acid scarification for 30 secs; Warm water soaking with 50̊ C temperature for 50 min; Tap water soaking treatment for 12 hrs and control (with-out any pre-sowing treatment). Among the various treatments under study, the seeds treated with GA3 750ppm for 12 hrs was significantly superior over rest of the treatments in all germination and growth parameters under study viz. days required for germination (8.87days); 50% germination (11.47days); germination percentage (87.81); survival percentage (85.52), plant height (105.54cm); Girth (9.51mm); No. of leaves (35.76), fresh weight of shoot (59.62 g); dry weight of shoot (26.61 g); length of primary root (58.62 g); number of secondary roots (15.53); fresh weight of root (47.68 g); dry weight of root (22.91 g); vigour index I (9267.46); Vigour index II (2358.20).
