Abstract
The experiment was conducted employing randomized block design with three replications, and the study consists of 12 treatment combinations in total using different concentration of Indolebutyric acid (IBA) in liquid, powder and paste form as well as using of white polywrappers (WP) and black polywrappers (BP). The best treatment was T11 with IBA Powder form@ 10000 ppm + BP which showed the highest root and growth parameters. With respect to number of primary roots, length of primary roots, diameter of primary roots, number of secondary roots, length of secondary roots, diameter of secondary roots, and dry weight of roots, T11was found superior. At 90 days after planting,70% success in rooting, 71.02% survival percentage, number of shoots per layer 7.78 and 15.56 number of leaf per plant was significantly (p>0.05) found higher as compared to other treatment combinations. Further, T8 (IBALiquid @ 10000 ppm + BP secured second position whereas minimum values were recorded in T3with IBA Paste @ 5000 ppm + White polywrapper.
