Nepali Oblong. The experiment was designed in Factorial Completely Randomized Design (CRD) and consisted of total thirty two (32) treatment combinations, which contained seasons i.e., rainy and spring, IBA concentrations i.e., 1000 ppm, 1500 ppm, 2000 ppm & control (treated only with distilled water) and four growing media i.e., soil + FYM + sand, soil + peat moss + sand, soil + sand and soil alone. The experiment was replicated thrice with 30 cuttings in each replication; therefore total 1440 treated cuttings were planted on raised bed under agro- shade net in each season. After two seasons of experimentation, rainy season showed maximum survival percentage (51.46 %), minimum days taken to first sprouting (19.75 days), highest number of roots (33.28), sprouting percentage (54.75 %), length of longest root (5.81 cm), average fresh and dry wt. of cuttings (3.46 g & 1.31 g, respectively). Among the media, soil + peat moss + sand reported maximum survival percentage (47.92 %), minimum days taken to first sprouting (20.04 days), highest number of roots (28.17), sprouting percentage (54.14 %), length of longest root (5.99 cm), average fresh and dry wt. of cuttings (3.55 g & 1.46 g, respectively). Among the IBA concentrations, IBA @ 2000 ppm performed best with respect to maximum survival percentage (47.50 %), minimum days taken to first sprouting (20.37 %), maximum number of roots (27.02), sprouting percentage (55.33 %), length of longest root (6.10 cm), average fresh and dry wt. of cuttings (3.72 g & 1.41 g, respectively). Highest B: C ratio (2.76) was recorded in cutting planted during rainy season treated with IBA @ 2000 ppm containing soil + peat moss + sand growing media.EnglishThesis
