Abstract: An experiment was conducted during 2016 at New Orchard, department of Horticulture, College of Agriculture, UAS, Dharwad to study the effect of pre-soaking chemicals on germination and subsequent seedling growth of papaya (Carica papaya L.) Cv. Solo. Pre-soaking of seeds with GA3 at 100 ppm had significant effect and taken less number of days to plumule appearance (15.00), emergence of true leaf (22.33), completion of germination (35.00), high rate of germination (0.028) and highest length of tap root (25.83 cm) as compared to other treatments. KNO3 at 1 % had significant influence on germination percentage (70.00 %) and number of lateral roots per seedling (33.80) as compared to other treatments.Pre-soaking of seeds with thiourea at 1000 ppm had significant influence on height of seedling at 60 DAS (18.40 cm), number of leaves at 60 DAS (9.00) and vigour index- I (2896.09) as compared to control. GA3 at 200 ppm had significant increase in girth of seedling at 60 DAS (5.77 mm), leaf area at 60 DAS (56.00 cm2), total fresh weight (17.02 g) and total dry weight (2.46 g) of seedling, vigour index-II (134.89) and quality index (0.35) of seedling.
