ABSTRACT
An experiment entitled “Effect of Bio-regulators and Chemical on Seed Germination and Seedling Growth in Papaya (Carica papaya L.) cv. Pusa Nanha” was conducted at Horticultural Research Centre and Department of Horticulture, Chauras Campus, H.N.B. Garhwal University, Srinagar (Garhwal), Uttarakhand, India during the year 2015-16. The treatments comprised of Thirteen levels of bio-regulators and chemicals viz., T1(GA3 100ppm), T2 (GA3 150ppm), T3 (GA3 200ppm),T4 (GA3 250ppm), T5 (NAA 100ppm), T6 (NAA 200ppm), T7 (NAA 300ppm), T8 (NAA 400ppm), T9(Thiourea 1000ppm), T10(Thiourea 1500ppm),T11 (Thiourea 2000ppm), T12(Thiourea 2500ppm), T13(Control). The experiment was laid out in Randomized Complete Block Design (RBD) with thirteen treatments and replicated thrice. The seeds treated with 400 ppm NAA showed the minimum number of days required for first germination (12.00 days), maximum germination percentage (77.78%), height of seedling (19.90cm), number of leaves per seedling (18), fresh weight of seedling (7.71g), number of roots per seedling (28.00), dry weight of seedling (1.68g). On the basis of result achieved in the present study, it can be concluded that among the bio-regulators and chemical, NAA @ 400 ppm may be suggested for seed germination and seedling growth of papaya cv. Pusa Nanha under valley condition of Gharwal Himalaya.
Key words: Bio-regulators, Growth, Seedling, Germination.
