This research was conducted during the seasons (2017, 2018), on pistachio trees var.' Ashouri' planted in Bsireen village at Hama governorate, in order to study the effect of different levels of poultry manure in the leaf nutrients content, leaf area and production of pistachio trees var.

Ashouri.

Five rates of poultry manure were applied (10, 15, 20, 25, 30 kg / tree) which are named (T10, T15, T20, T25, T30) and compared to chemical fertilizer (TNPK treatment) as applied by the farmer, and with a control without any fertilizer additive (To).

The experiment was designed as Complete Randomized Blocks Design.

The used manure fertilizer showed a positive effect in improving leaf nutrient content of (N, P, K, B), and the best treatments were T20, T25, and T30.

The treatment T30 also showed the highest increase of leaf area (202.37 and 198.96) cm² for the two seasons, respectively.

Concerning production the treatments T20, T25 and T30 exceeded significantly all the rest ones, so in light of these results and from an economic point of view, fertilization with poultry manure at a rate of 20 kg / tree is recommended for good productivity of pistachio tree var.
