The experiment was carried out during the year 2021-22 at Department of Fruit Science, Guru Kashi University Talwandi Sabo, Bathinda, Punjab, India. The cuttings were taken from hardwood cutting arising on tree of pomegranate cv. Bhawga, Ganesh, Mridula during the month of January. The experiment was conducted in Randomized block design with 6 treatment and 3 replication. Treatments were consisted of control (0), 1000ppm, 1500ppm, 2000ppm, 2500ppm, 3000ppm. Result showed that the IBA 3000ppm concentration solution for dip in 10 seconds gives shows highest number of primary roots per cutting was recorded in Bhagwa (38.98), Ganesh (37.40) and Mridula (35.87). The maximum survival percentage was recorded with IBA 3000ppm Bhagwa (96.33%), Ganesh (84.67%) and Mridula (80.67%). The maximum number of days taken for first sprouting was recorded in IBA 3000ppm Mridula (13.20), Bhagwa (11.53) and Ganesh (12.47). The maximum leaf area per cutting was recorded in IBA 3000ppm Bhagwa (301.17 cm), Ganesh (259.70 cm) and Mridula (282.97 cm). The highest plant height was observed in IBA 3000ppm Bhagwa (56.97 cm), Ganesh (52.93cm) and Mridula (55.87 cm).
