The experimental objectives were to study the effect of different growing media on rooting performance as well as to find out the effect of IBA concentrations on rooting performance. The experiment was laid out in a Completely Randomized Design (CRD) with three replications comprising of seven treatment combinations viz., T1: Sand (Control), T2: (Soil + Sand) (1:1) + IBA (500 ppm), T3: (Soil + Sand) (1:1) + IBA (1000 ppm), T4: (Soil + FYM) (1:1) + IBA (500 ppm), T5: (Soil + FYM) (1:1) + IBA (1000 ppm), T6: (Soil + Sand + FYM) (1:1:1) + IBA (500 ppm), T7: (Soil + Sand + FYM) (1:1:1) + IBA (1000 ppm). To record the data on various growth parameters three representative cuttings were randomly selected from each replication. Among different treatments, significantly maximum survival rate, plant height, total root length, average root diameter of primary and secondary roots, average length of longest root, average diameter of longest root, dry weight of roots, fresh weight of roots, dry weight of shoot, fresh weight of shoot, number of primary and secondary roots per cutting and number of shoots per cutting were recorded in T7: {Soil + Sand + FYM + IBA (1000 ppm)}.EnglishThesis
