Abstract: An experiment was conducted at Department of Horticulture, SHUATS, Prayagraj, Uttar Pradesh with an objective to evaluate the influence of different concentration of phytohormones on seedling growth of Karna Khatta. The experiment was laid in Randomized Block Design with fourteen treatments replicated thrice. Seeds are treated with phytohormones and plant growth promoting micro - organism over night before sowing in polybags. The various concentration of phytohormones viz. GA₃ and NAA, plant growth promoting micro -organisms viz. Aspergillus, Pseudomonas and Photosynthetic Bacteria and there combination were used to treat the seeds and further observation were taken for 120 Days. The maximum results indicated that the shoot length (85.23 cm), seedling girth (15.33 mm), number of leaves (57.66), seedling length (18.70 cm), seedling vigor index (1,663.73), leaf area (38.56 cm²) recorded in seeds which are treated with GA₃ 80 ppm for 24 hours. Therefore, it is evident that the GA₃ at 80 ppm was found best in terms of vegetative growth.
