Abstract:
The present investigation entitled “Influence of different pre-sowing treatments on seed germination and seedling growth parameters of Custard apple (Annona squamosa L.)” was carried out during the year 2022-2023 at Centre of Excellence on Protected Cultivation and Precision Farming, Department of Fruit Science, College of Agriculture, IGKV, Raipur (C.G.). The experiment was employed in Completely Randomized Design having thirteen different treatments, which replicated thrice. The different pre-soaking agents were i.e. cow dung, cow urine and GA3 with their different concentrations. The seeds treated with GA₃ @ 200 ppm took minimum days to start germination (23.33 days), 50% germination (46.66 days) and the germination percentage (83.33%) of custard apple was found maximum under the same treatment. The plant growth parameters viz. plant height (15.68 cm), number of leaves per seedling (13.66) and girth of stem (3.71 mm) at 120 days after sowing influenced significantly under the seeds treated with gibberellic acid @ 200 ppm, which was closely followed by cow dung (100%).
