Performance of IBA and NAA Concentrations for Shoots in Fig (Ficus carica L.) Cv. Dinkar

Abstract

The experiment on performance of IBA and NAA concentrations for shoots in Fig (Ficus carica L.) cv. Dinkar. was carried out at Central Nursery, Vasantrao Naik Marathwada Krishi Vidyapeeth Parbhani during kharif season in year 2018-19. The objective was to find out suitable concentration of growth regulators for Shoots and success of air layer. The experiment was laid out in Randomized Block Design in Nine treatments with three replications. The treatments were T1 (IBA-2500 ppm), T2 (IBA-5000 ppm), T3 (IBA-7500 ppm), T4 (IBA-10000 ppm), T5 (NAA-2500 ppm), T6 (NAA-5000 ppm), T7 (IBA+NAA-2500+ 2500 ppm), T8 (IBA+NAA-5000+ 5000 ppm) and T9 (Control).
 The treatment T3 (IBA 7500 ppm) also significantly influenced in regards to shoot growth parameters as it recorded minimum number of days required for first sprouting (10.10), length of shoot (6.67, 13.67 and 18.67 cm), number of leaves (6.22, 7.99 and 9.88), number of sprouts (2.87, 4.77 and 6.66), number of shoots (3.54, 5.44 and 7.33), stem girth (2.13, 3.13 and 4.28 cm), seedling height (14.67, 21.68 and 27.66 cm) at 30, 60 and 90 days after transplanting respectively. The treatment T3 (IBA 7500 ppm) also recorded the maximum success percentage (96.33%) and benefit cost ratio (1.81) after 90 days of transplanting.
