An experiment was conducted to study the effect of Indole-3-Butyric acid (IBA) concentrations on hardwood cuttings of Eureka seedless under normal field condition at Paklihawa, Rupandehi, Nepal from August 11 to November 27 in 2022. The experiment was laid out in Randomized Complete Block Design with 7 treatments and three replications. Seven concentrations of IBA (T1: control, T2: 500ppm, T3:1000ppm, T4: 1500ppm, T5:2000ppm, T6: 2500ppm and T7: 3000ppm) were examined on root and shoot growth performance of cuttings. The highest average number of primary root (17.5), total number of roots (30) and average length of the longest root (22.55), were found in cuttings treated with 2500 ppm which had significant effect over control. The lowest average number of primary root (4.5), length of the shortest roots (5.9), and total number of roots (10) were recorded in control treatment. Likewise, the highest number of shoots (3.5) and leaves (16.5) were found in cuttings treated with 2500 ppm which had significant effect than other treatments. However, the highest average length of shoot (15.55 cm) and width of leaf were observed in 1500 ppm treatment and maximum sprouting (87.5%) was found in cuttings treated with 500 ppm IBA. Considering the effect of IBA on different root and shoot growth parameters, hardwood cuttings treated with 2500 ppm performed best for root and shoot growth and further establishment of new saplings.
