Effect of ga3 and growing media on seedling growth of papaya (Carica papaya L.) cv. pusa Nanha

The present study was carried out to investigate “Effect of GA3 and growing media on seedling growth of papaya (Carica papaya L.) cv. Pusa Nanha”. The study revealed that the treatments comprised combinations of soil, FYM and vermicompost with varying levels of GA3. The result indicated that GA3 200 ppm is found to be the most effective for better root growth parameters (number of primary and secondary roots, length of primary and secondary roots, fresh and dry weight of roots), shoot growth parameters (height of the seedling, number of leaves, girth of seedling, average leaf area, fresh and dry weight of shoot) and survival percentage whereas root/shoot ratio was maximum reduced in GA3 150 ppm. Among different growing media soil + FYM + vermicompost (1:1:1) recorded 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, the combination of GA3 200 ppm and growing media soil: FYM: vermicompost (1:1:1) was found most suitable for better growth of papaya seedling.
