The experiment was conducted at the horticultural station in Al-Mahaweel district, 20 km north of Babylon province, which is affiliated to the Horticultural Department / Ministry of Agriculture.To study the effect of three types of naphthalene acetic acid (NAA), Naphthalene acetic acid, Indole-3-butyric acid, and 2,4-D Dichlorophenoxyacetic acid, with three concentrations (0, 1, 2) ppm, on the two cultivars of palm trees, Al-Sayer and Al-Barhi. Three replicates for each treatment, in order to improve the quality of the fruits and increase the yield. The experiment conducted two factors (2 x 3 x 3) for the two cultivars according to the Randomized Complete Block Design (RCBD) , with a palm tree for each replicate.The results showed the 2,4-D excelled on the rest of the above-mentioned auxins in all the studied traits, and the concentration (2)) ppm excelled on the other concentrations in all the studied traits.The results also showed the Al-Barhi cultivar excelled in the characteristics of diameter, fruit weight and yield quantity, while the Al-Sayer cultivar was excelled in trait of fruit length, and the weight of the bunch did not have a significant effect between the two cultivars.The bi and triple interaction had a significant effect on most of the traits studied above.
