Seed germination is the most important aspect for raising the nursery for successful seedling production of Papaya. The present study was carried out to explore the effect of different growth promoter with growing media on seed germination of Papaya. (Carica papaya L.) cv. Madhubindu under net house condition. The seeds of papaya were treated with different concentrations of GA3 and cow urine and sowing in different growing Media’s viz., Coco peat, Vermicompost and Soil. Highly significant different was observed between the treatments. The results showed that the treatment combinations G3M1 [GA3 @150 mg/l dipping for 12 hours and soil + cocopeat (1:1)] is significantly recorded highest germination percentage (84.00% and 95.00%) at 10 and 20 DAS, respectively and also recorded significantly minimum number of days (8.33) required 50 per cent germination. Whereas, treatment combination G6M1 [cow urine 10% dipping for 18 hours and soil + cocopeat (1:1)] recorded significantly the highest seed vigour index- I and II, dry weight of shoot and dry weight of root at 30 and 45 DAS. Similarly, the highest root: shoot ratio at 30 and 45 DAS and seed vigour index- II at 30 DAS was recorded in treatment combination G5M1 [cow urine 10% dipping for 12 hours and soil + cocopeat (1:1)].
