Abstract:
The experiment was conducted as investigate “Effect of gibberellic acid (GA3) and growing media on seedling growth parameters of papaya (Carica papaya L.) cv. Pusa Nanha”. In this study the treatments comprised with different combinations of soil, FYM and vermicompost with varying levels of GA3. The experiment was laid out in Factorial Complete Randomized Block Design. The findings showed that GA3 200 ppm is found most effective for better root growth parameters (like viz., number of primary and secondary roots, length of primary and secondary roots, fresh and dry weight of roots), shoot growth parameters (height of seedling, number of leaves, girth of seedling, average leaf area, fresh and dry weight of shoot) and survival percentage whereas maximum reduced root/shoot ratio was in found with GA3 150 ppm. Among the different growing media, the growing media combination, soil + FYM + vermicompost (1:1:1) observed higher values for root growth parameters, shoot growth parameters and survival percentage of papaya seedlings. The treatment combination of GA3 200 ppm and growing media soil: FYM: vermicompost (1:1:1) showed better root growth parameters and shoot growth parameters and survival percentage. Therefore, it concluded that the combination of GA3 200 ppm and growing media soil: FYM: vermicompost (1:1:1) was most suitable for better papaya seedling growth.
