Abstract:
The research was carried out in Al-Suqaylabiyah – Hama Governorate during two seasons (2020-2021 and 2021-2022), on trees of the Pistachio Ashouri variety that were about 25 years old. The aim was to study the effect of foliar spraying with some microelements on the productivity and quality of their fruits. The experiment was designed according to complete randomization blocks using 8 treatments and three replicates for each treatment, with an average of one tree per experimental plot. The results showed that the foliar spraying of some microelements contributed to increasing the amount of production and improving the quality of fruits. The treatment of spraying with (Zinc Sulfate 1000 ppm with Ferrous Sulfate 300 ppm) or Zinc Sulfate 1000 ppm were significantly superior to the remaining treatments in high-productivity. The treatments of spraying Copper Sulfate 200 ppm, or Zinc Sulfate 1000 ppm or Ferrous Sulfate 300 ppm had the highest percentage of cracked fruits (89.84 – 89.39 -89.20%) respectively, and the lowest percentage of empty fruits (11.41-11.71-11.52)% respectively, while the effect of spraying was not significant on the percentage of fruit extraction.
Key words: pistachio, foliar spray, yield, fruits characteristics, microelements.
