Abstract: An experiment entitled “Role of pre-sowing seed treatment on germination behavior and seedling vigour of papaya (Carica papaya L.)” was conducted at Instructional cum Research Farm, College of Agriculture and Research Station, (IGKV), Bemetara, Chhattisgarh, India during the year 2018 and 2019. The experiment was laid out in Completely Randomized Design (CRD) with Seventeen different treatments replicated three times. The papaya seeds were sown in polybags which was filled with common media and treated with three different concentration of GA₃ (viz., 50, 100 and 150) and 10 per cent cow urine with addition of bio-fertilizers in media soil. The results revealed that the application of treatment T₁₁ (seed soaking with 150 ppm GA₃ + 12 hours + azotobacter) was given early germination, rate of emergence as well as highest germination percentage, seed vigour index – I and seed vigour index – II. While, T₁₅ (seed soaking with cow urine 10 (%) + 12 hours + azotobacter) had given maximum root: shoot ratio.
