An experiment was conducted to evaluate the effect of varying node numbers and indole-3-butyric acid (IBA) concentrations on the growth parameters of cuttings. The study was conducted with completely randomized design with factorial concept comprising 12 treatment combinations: three node numbers-two (N₁), three (N₂) and four (N₃) nodes and four IBA concentrations-250 ppm (I₁), 500 ppm (I₂), 750 ppm (I₃) and 1000 ppm (I₄), each replicated three times. Results showed that cuttings with four nodes (N₃) produced the highest number of branches (4.74, 6.75, 7.82, 8.06), leaves (12.75, 17.87, 23.47, 29.21) and vine length (135.67 cm, 149.42 cm, 169.54 cm, 171.63 cm) at 30, 45, 60 and 75 days after planting. Among the IBA treatments, 250 ppm (I₁) recorded the highest number of leaves (10.61, 15.29, 22.53, 28.06), branches per cutting (3.77, 6.27, 6.43) and vine length (113.99 cm, 140.95 cm, 154.52 cm) at 30, 60 and 75 DAP. The combination of four nodes and 250 ppm IBA (N₃I₁) resulted in the highest branches (5.43, 7.31, 8.74, 9.25), leaves (13.48, 19.55, 25.91, 33.30) and vine length (161.41 cm, 184.27 cm, 192.25 cm, 207.93 cm) at 30, 45, 60 and 75 DAP. Thus, four-node cuttings treated with 250 ppm IBA showed superior growth performance across vegetative parameters.
