Abstract: A study to assess the effect of chemical drenching to improve the growth and vigour of papaya seedlings raised in cocopeat medium was conducted at College Orchard, Horticultural College and Research Institute, TNAU, Coimbatore during January to May, 2018. The experiment included nine treatments viz., control (T1-without drenching), Di ammonium Phosphate (DAP) @ 0.5% (T2), Di ammonium Phosphate (DAP) @ 1.0% (T3), Potassium dihydrogen orthophosphate (KH2PO4) @ 0.5% (T4), Potassium dihydrogen orthophosphate (KH2PO4) @1.0% (T5), 19-19-19 @ 0.5% (T6), 19-19-19 @ 1.0% (T7), Humic acid @ 0.5% (T8), Humic acid @ 1.0% (T9) at seven days interval on 30 DAS, 37 DAS and 44 DAS. The morpho-physiological and the biochemical traits of the papaya seedlings were recorded at 37 DAS, 44 DAS and 51 DAS. The experiment revealed that drenching of papaya seedlings with humic acid @ 1% was found to significantly influence the growth and vigour of seedlings raised in cocopeat medium. Among the different parameters observed, seedling height, leaf area, shoot length, fresh weight and dry weight of shoot and root, leaf nutrient contents (N, P, K), leaf chlorophyll content and leaf soluble protein content were found to be significantly influenced by the treatments imposed.
