Asexual propagation of Jamun (Syzigium cumini L. skeels) through cutting is the easiest, convenient and the cheapest method to obtain true to type plants in considerably lesser time. In the present study, effect of different growing media on the shooting ability of different types of stem cuttings of Jamun was assessed at School of Agriculture, Lovely Professional University, Phagwara, and Punjab. The experiment was laid out in randomized block design. The hardwood cuttings were significantly best with respect to most of the shoot parameters. In the interaction of treatments, number of days taken for sprout initiation was found early in T3 (soil+vermi-compost+sand +IBA (5000 ppm), 12.13 days), the highest number of sprouts (11.36, 9.8 and 7.33) and number of leaves per cutting (5.7, 7.00 and 8.93) at 30, 60 and 90 DAP, the highest diameter of shoot was found in T5 (1.56, 1.8, 2.66) at 30, 60 and 90 DAP, the highest survival percentage was found in T5 (IBA 3000 ppm+NAA 1000 ppm) (60.8), the highest leaf area was found in T5 (68.8) and highest plant height observed in T5 (85.33 cm) at 90 DAP. Overall, T5 (IBA 3000 ppm+NAA 1000 ppm) having interaction of hard wood cutting was shown superior results as compared to other treatments.
