This study was carried out during two growing seasons 2013 and 2014 to investigate the effect of using olive mill water (OMW) on some pomological property of fruit and yield in two olive cultivars (Zard and Rughani) that grown in a loamy soil under drip irrigation system in Manjil area of Guilan Province, Iran. Different levels of OMW (0, 90, 190 and 380 liter/tree) were added in the end of canopy shad of olive trees at one stage in late November. A factorial experiment were arranged in a randomized complete block design with three replications. For each replicate, two trees were used as sampling units for each cultivar. Statistical assessments of differences between mean values were performed by the LSD test at P=0.01 according to Tukey test. The results showed that not only different amounts of OMW had no a negative impact on all parameters but also in Rughani cultivar the trees that treatment with different levels of OMW had higher yield (tree-1 and ha-1) than the control in the same cultivar. Maximum of yield belonged to 380 (L tree-1) and control in Zard cultivar. Cultivars showed a highly significant effect (p<0.01) on many characters. The results showed that Zard cultivar had higher yield, fruit weight, fruit diameter, pulp fresh weight, pit weight than Rughani cultivar (p < 0.01). It had lower pulp dry mater than Rughani Cultivar (p < 0.01). No significance between two cultivars with regard for fruit length.
