C.F. Liang & A.R. Ferguson]” were carried out at the Experimental Farm of Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry Nauni, Solan HP during 2018-19. The experiment was laid out in Randomised Block Design. Three rooting media viz., Perlite, Vermiculite and Coco peat (alone or in equal proportions) were used along with the two IBA (4000 ppm and 6000 ppm) concentrations. Equal proportion of Sand and Soil with IBA (5000 ppm) a standard practice was used as control. Therefore, in all fifteen treatments were replicated thrice. Coco peat + IBA @ 6000 ppm significantly increased the shoot diameter (5.48 mm), number of leaves per cutting (32.91), leaf area (89.06 cm2), number of roots per cutting (40.33), rooting (45.83 %), fresh and dry weight of shoots (32.59 g and 15.66 g) and roots (23.75 g and 11.23 g), total biomass (26.89 g), shoot: root ratio (1.40: 1), survival rate (55.83 %) and saleable plants (44.16 %) in hardwood cuttings of kiwifruit. However, sprouting (84.17 %) and shoot length (179.89 cm) were maximum with Perlite + Coco peat + IBA @ 6000 ppm and Perlite + IBA @ 6000 ppm, respectively,but statistically at par with Coco peat + IBA @ 6000 ppm. The performance of standard practice i.e. Sand + Soil + IBA @ 5000 ppm was not found to be satisfactory in all the growth parameters recorded. The benefit: cost ratio (2.82: 1) was estimated to be the highest with treatment T6 (Coco peat + IBA @ 6000 ppm).ennullThesis
