Abstract :

The current investigation aims to study the effects of different IBA concentrations and growing media on karonda cuttings at Research Farm, Faculty of Agriculture, Division of Fruit Science at Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main Campus, Chatha during the year 2018-19. The treatments consisted combination of three levels of IBA (7000, 8000 and 9000 ppm) with three different concentrations of sucrose (3, 4 and 5% respectively) and also contains the three different types of rooting media viz., soil, sand, FYM (1:1:1), vermiculite (100%) and cocopeat (100 %) which was laid out in a factorial completely randomized design with three replications. The results obtained from the study exhibited that the shortest time to first sprouting i.e. 9.5 DAP, maximum sprouted cuttings i.e. 16.00, the maximum percentage of cuttings that sprouted i.e. 80 percent the longest shoot (8.46 cm), maximum number of shoots per cutting (6.15), longest diameter of shoot (8.31 mm), maximum shoot fresh weight (2.21 g), maximum shoot dry weight (1.16 g), highest leaf number per cutting (16.80), total leaf area (4.26 cm2), maximum leaf fresh weight (0.27 g), maximum leaf dry weight (0.14 g) and maximum leaf chlorophyll content (SPAD value of 75.20) were recorded with combination of 8000 ppm IBA, 4 percent sucrose and vermiculite media. Furthermore, the total number of roots per cutting (13.12), longest root length (8.46 cm), mean root length (11.30 mm), root fresh weight (0.53 g), root dry weight (0.29 g) and survival percentage (43.33) were also found to be highest with 8000 ppm IBA, 4 percent sucrose and vermiculite media. From this study, it is concluded that the combined effect of 8000 ppm IBA, 4 percent sucrose and vermiculite had a great impact on the successful propagation of karonda by cuttings, as it yielded best results in terms of growth and rooting parameters.
