Abstract: Rooting in hardwood cuttings of olive was investigated at the College of Agricultural Engineering Sciences, University of Sulaimani, Kurdistan Region-Iraq under application of licorice and willow extracts with concentrations of (0, 3, 6 and 9 g.L-1). The extracts were prepared from licorice root and willow shoots in 25% ethanol heated in a water bath at 40ºC for 3 hours, refrigerated for 24 hours and filtered through filter paper. The hardwood cuttings of olive cv. (Sorani) were taken from basal part of one-year-old suckers then soaked in the licorice and willow extract concentrations for 1 hour. The results revealed that the highest (66.66%) rooting was achieved in the cuttings soaked in 6 and 9 g.L-1 licorice extract for 1 hour, they were not different in comparison with control cuttings which gave (49.99%), but rooting percentage was reduced (38.8%) in the cuttings soaked in 6g.L-1 willow extract. The cuttings soaked in 9 g.L-1 willow extract and 6 g.L-1 licorice extract gave the best root number, root length, shoot length, shoot diameter and leaf number. Generally, depending on the obtained results in this study, 6 and 9 g.L-1 licorice extract with 9 g.L-1 willow extract have possibility to use as an alternative to induce root formation and improve root and shoot quality of the cuttings in olive.
