Seven olive genotypes (D1, Dd1, GW, Ps1, Bn3, Bn6 and Ds17) used as plant materials. A split plot experiment in time was used based on a completely randomized block design with three replications and three irrigation regimes for field experiment. Irrigation treatments period for field experiment were 6, 9 and 12 days interval and 6 days period was as control. Some vegetative characteristics such as plant height, trunk diameter, leaf number, leaf, shoot, and root fresh and dry weight were recorded. Result in field experiments show that Ds17 genotype had the highest trunk diameter and Dd1 genotype had the lowest trunk diameter. Bn3 genotype had the highest number of leaf and D1 had the lowest but D1, Dd1 and GW were in a statistic class. Genotypes show significant differences in leaf fresh and dry weight so that Bn3 genotype had the highest leaf fresh and dry weight and D1 had the lowest. Genotypes show significant differences in shoot and root fresh and dry weight so that Ds17 genotype had the lowest shoot fresh and dry weight and GW had the lowest root fresh and dry weight. The results indicated that olive genotypes had different resistance to drought and vegetative growth status of Bn3 and Ds17 genotypes were better in drought stress conditions.
