Abstract
An experiment was conducted to find out suitable growth hormone and growing medium for germination and seedling growth of papaya. The treatments included soaking the seed of papaya variety Red lady in GA3(200ppm) for 24.00 hours except for control. The perforated polythene bags of 4 x 5 cm size (150 gauges thickness) were used for sowing. The bags were filled with a mixture of Soil, Vermicompost, Cinder and Cocopeat in the ratio of 1:1:1, 1:2:1, 1:1:2 and 2:1:1. Experiment was laid out in Completely randomized design nine treatment with three replication. Findings indicate that treatment T9 Soil +Cocopeat +Vermicompost +Cinder (1:1:1:1) +GA3 200ppm performed best in terms of growth parameters viz., germination (77.37), days taken for completion of germination (15.27), seedling height (25.00 cm), number of leaves per seedling (13.53 cm), diameter of seedling (cm) (1.03), Leaf area (cm2) (97.64cm), Chlorophyll content (SPAD Value) (54.97), Length of longest tap root (4.52 cm) and Survival (%) (83.27) under Prayagraj agro-climatic condition.
