Abstract: A research experiment was conducted during rabi 2019-20 under greenhouse to study the effect of pre sowing treatments on seed germination and its parameters in sandalwood. Among seven different pre sowing treatments viz., GA₃ 100 ppm (T₁), GA3 300 ppm (T₂), KNO₃ at 2% (T₃), Cow dung for 24 hours (T₄), Cow dung for 48 hours (T₅), Ethrel 100 ppm (T₆) and Control (T₇), pre sowing seed treatment with GA₃ 300 ppm (T₂) recorded significantly early emergence of seedling (34.66 days) with maximum germination per cent (34.66%), speed of germination (0.64), mean weekly germination (3.03), collar diameter (2.23 mm), seedling fresh weight (243.16 mg), seedling dry weight (50.00 mg), seedling vigour index (length) (319.15) and seedling vigour index (mass) (1743.83). The root length (4.25 cm), shoot length (5.27 cm) and seedling length (9.55 cm) were found significantly highest in KNO₃ at 2% (T₃).
