Where this study allowed to evaluate the discrepancy between the fruits of the three studied varieties according to trends . The results showed a great diversity between the characteristics of the fruits according to the varieties and trends, where we found that the largest average length of the fruit on the east side was estimated at 3.82 cm, and the lowest average length in the south was estimated at 3.63 cm. As the average weight of the whole fruit, the lowest weight on the eastern side was estimated at 5.67g , and the largest weight on the western side was estimated at 6.24g. A difference was also found in the average length of the kernel, which ranges from 2.37 in the east to 2.74 cm in the north. On the other hand, we found a difference in the weight of the kernel, which ranges from 5.15 g from the north side to 5.37 from the west side. As for the average number of Arjoun Dates , we found the largest number on the south side, estimated at 5Arjoun Dates, and the lowest number on the north side, estimated at 2Arjoun Dates.
