Investigation were conducted to propagate olive (Olea europea L.) from hardwood cuttings by the use of IBA (Indole butyric acid) and IAA (Indole acetic acid) each with 1500 ppm, 3000 ppm and 6000 ppm. The cuttings were dipped in the above growth regulators for 5 minutes duration as "quick dip" method before planting in the experimental field. Better rooting of 70% was produced by IBA at 3000 ppm. More number of roots per cutting (10.75) were noted in IBA at 6000 ppm IBA at 1500 ppm significantly increased the length of roots to 5.0 cm. The control (untreated cuttings) completely failed to produce any roots. The effects of various concentrations of IAA were not so pronounced as compared to IBA.
