In order to enhance the establishment of olive plantation in the Kingdom of Saudi Arabia (KSA), an investigation was carried out to improve the rooting ability of olive cuttings. This research aimed to study the effect of three substrates (sand, peat moss, perlite) and IBA treatment (at 0 and 4000 ppm) on rooting ability of three olive cultivars (Arbequina, Koroneiki and Picual). The percentage of cuttings that rooted, the number of roots produced by cutting, the average root length and the survival rate were recorded. These parameters were significantly influenced by the interactive effect of substrates, cultivars and IBA treatment. The semi hardwood cuttings planted in perlite and sand had higher rooting percentage than those planted in peat moss with a significant difference between cultivars. Very low rooting occurred in cuttings dipped in distilled water (control) for all cultivars and in all substrates. At 4000 ppm IBA, Arbequina and Koroneiki cultivars gave high results while Picual cv. recorded worst performance in all the substrates tested. Results in relation to the physical properties of the substrates used in this experiment were also discussed. © 2013 Academic Journals Inc.
