Effect of Improved Technologies on certain Quantitative and Qualitative Characteristics of Aleppo Pistachio Trees (Ashoury Variety) Grown in Idlib Governorate / Syria.

The stud y was conducted during the years 2006 , 2007 and 2008 in the province of Idlib (region of Khan Sheikhoun, hand Altmanah). The study aims to investigate the impact of the most important operations of the service (irrigation, fertilization, pruning) in the power of growth and some specifications of quality in the productivity of tree pistachio, using supplementary irrigation rate of 400 liters / tree and multiple dates (4 dates) and organic fertilization rate of 3 cubic meters / donom on 10/ 12 and the chemical fertilizer azotic rate of 2 kg of urea per tree and so on 6/ 3 of each year during the years of research. The pruning was performed on the annual average 17/ 2 of each year. While the untreated control trees did not receive any treatment. The results showed that the average growth rate of vegetative annual branches of the studied trees transaction has reached 11.5 cm while the control was only 4.75 cm which mains the number in treated trees was more than double its value in the control tree during the years of research. Furthermore, the average number of fruity buds was significantly higher in the treated trees than its value in the control trees as the average number of fruity buds was 7 buds on the treated trees and only 4 buds in the control trees. We also noticed an increase in the average area of flat leaf at the end of the growing season on the treated trees compared to control trees, so the average was 28.5 cm2 for the treated trees and only 24.5 cm2 for the control ones . Additionally, we observed an increase in the average productivity for the treated trees as the production of treated trees was 35 kg and only 22 Kg for the control ones. Besides that, improvements in some specifications related to the fruit quality in the treated plants were observed (i.e. the rate of 100 seeds to the soft flesh and wood cover and the nucleus and the rate of cracked fruits). These results can be explained by the impact of services applied to pistachio trees 1 Donom = 1000 m2.
