Abstract
This research was conducted during the seasons 2017 and 2018 on pistachio trees var.’ Ashouri’ which grown in Bsireen village at Hama governorate, in order to study the effect of different levels of poultry manure on the production of pistachio trees var. Ashouri. Five rates of poultry manure were applied (10, 15, 20, 25 and 30 kg/tree), and the treatments were (T2, T3, T4, T5 and T6 respectively) which compared to chemical fertilizer (T1 treatment) as applied by the farmer, and with a control without any fertilizer addition (T0). The experiment was designed according to randomized complete block design. The results confirmed the positive effect of manure treatments on the productivity indicators of pistachio trees which clearly observed at the second season. The highest production per tree were (34.49, 34.58 and 34.83 kg) for the treatments (T4, T5 and T6) respectively, and all treatments surpassed the control. In terms of fruits crack and empty fruits ratios the treatments T4, T5, T6 had the best values.
