The present investigation entitled “Effect of Organic and Bio-fertilizers on germination of papaya (Carica papaya L.) cvs. Red Lady and Pusa Dwarf” was conducted at Agriculture Research farm, Guru Kashi University, Talwandi Sabo, Bathinda, Punjab, India during 2021-2022.The experiment was carried out for the period during Rabi-Kharif season between February 2022 to April 2022. The experiment was laid out in randomized block design comprising of 13 treatment combinations replicated 3 times which consisted of papaya cultivars namely Red Lady and Pusa Dwarf. Among the cultivars, Red Lady showed early germination in (5.33) days, while Pusa Dwarf took (6.67) days for first seedling emergence was observed in both the cultivars. Red Lady took (7.67) days taken to 50 percent germination of seedlings, while Pusa Dwarf took (10.33) days for germination, showing germination percentage of 83.33% and 76.66% for both the cultivars. In case of growth parameters such as Plant height and number of leaves at 45 DAS, the maximum was recorded to be (18.26cm) & (10.06) for the cultivar Red Lady, while for Pusa Dwarf (14.23cm) & (8.93cm), respectively. Maximum leaf area at 45 DAS for Red Lady (30.55cm2) and Pusa Dwarf (28.72cm2) was observed and maximum stem girth at 45 DAS (1.56cm and 1.43cm) was also recorded. These all maximum observations were recorded under the treatment application of Cocopeat (10g) + A.M Fungi (5g) + Trichoderma harzianum (3g), respectively.
