There has been a steady demand for production and supply of olive sapling of different varient varieties for olive gardens in Iran but with regard to the fact that some varieties of olive such as kalamata and amigdafolia and conservalia which possess suitable characteristics arc found to be rather difficult in rooting for various reasons. Therefore, attempts have been made to adapt and grow them in different climatical areas of the country for restoration or development purposes and would be continuing in the future. For a survey of the rooting capabilities of the above mentioned varieties, a study was carried out in the framework of RCBD (Randomized Complete Block Design), having 64 treatments and 4 replications in a factorial. Proper treatments were made by means of feeding (spraying solutions) on the mother plants with microelements, (Zinc and Boron), during a period of one month prior to the preparation of the cuttings of the varieties and also by applying IBA (Indul-3-butiric acid) plant growth regulators with different concentrations and by application of Split on bark of the end of cuttings for enhancing the rooting process in the different varieties, such as kalamata, amigafolia, conservalia, and zard. Also zard were chosen as control. As a result of the study it has been found that prior spraying of the mother plants with the nutritional concentration Zinc and Boron had major effects on the improvement of rooting process and treatments with IBA hormones having a solution of 4500 ppm and also with IBA plant growth regulators having a solution of 4500 ppm together with Zinc as a microelement were the most influence for the above said varieties. Furthermore, the split on bark of the end of cuttings of the varieties had major effects the rooting process though the rooting percentage of the bark splitting treatments were significant effects than non- bark splitting treatments and finally significant difference with respect to the percentage of rooting among the varieties under study was observed. The rooting percentage of concervalia, zard, amygdalifolia and kalamata were counted 62. 03,58. 4,50. 47 and 40. 94 respectively.
