Effect of Washing and Non-washing of Seeds on Growth of Papaya Seedlings (Carica papaya L.) cv. Pusa Nanha

Abstract

The present experiment was carried out to investigate the response of washing and non- washing of seeds on growth of papaya seedling at the CRC Farm, ITM University, Gwalior (M.P.). The experiment was set up in the Randomized Block Design using 4 media with or without washing of seeds with tap water comprising 12 treatments combinations (viz., controlled (soil + water), vermiwash (50%) + wood dust, vermiwash (50%) + cocopeat, vermiwash (50%) + pond soil, cow-urine (50%) + wood dust, cow-urine (50%) + cocopeat, cow-urine (50%) + pond soil, vermiwash (100%) + wood dust, vermiwash (100%) + cocopeat, vermiwash (100%) + pond soil, cow-urine (100%) + wood dust, cow-urine (100%) + cocopeat, cow-urine (100%) + pond soil which were replicated thrice. For experimental purpose, freshly ripe fruits of papaya were purchased from the papaya-growing farmer of IARI, New Delhi and seeds were sown in the poly bag (4x24 inch sized). The results indicated that the application of application of Vermiwash (100%) + pond soil recorded maximum height of seedling (cm), number of leaves per seedling, stem diameter (cm), leaf area (158.41 cm2), fresh weight of seedling (8.49g), dry weight of seedling (1.17 g), dry weight of shoot (0.334g), dry weight of root (0.779), root/shoot ratio (2.34) as compared to without washing of seeds and other rooting media. Thus, application of Vermiwash (100%) + pond soil was found to the best treatment among all the treatments and it gave the maximum growth attributes which will inturn improve the yield of papaya.
