Terminalia tomentosa Wight & Arn is known for treating multiple aliments, is one of the most popular timber species. However, hard seed coat and low germination are hindering its use in afforestation, reforestation and commercial plantation programs. Study was conducted to study the effect of different pre-sowing treatmentson germination and growth of Terminalia tomentosa at Forest College and Research Institute, Mulugu, during 2021-2022. The experiment was laid out in completely randomized design with nine treatments and three replications. Presoaking treatment of seeds soaked in hot water for 24 hours (T4) has shown significantly superior performance with respect to germination percentage (71.11%), shorter germination period (12 days), survival percentage (93.75%) and growth attributes like root length (25.17cm), number of leaves (14.40), dry weight of root (13.3g) and dry weight of shoot (5g). It is because of the fact that hot water treatment gave earlier germination, which might be due to the stimulating effect of imbibitions on seed germination by affecting various factors, viz., seedcoat permeability for gases and water exchange and release of inhibitor whereas shoot: root ratio was maximum in T8 i.e. 50% concentrated H2SO4 for 5 minutes (0.72).
