Abstract:
This study was carried out in Hama governorate during the season (2022-2023) in order to predict the yield of pistachios based on climatic and temporal factors and the services provided to care for these trees. The study used two types of data, the first is the secondary data that represents the historical context of production, area, and rainfall rates, and the second is the primary data on production inputs and farm and farm characteristics, which was collected by the study questionnaire, which targeted a random sample of pistachio farmers in this governorate amounted to (132) farmers Distributed between irrigated and rain-fed areas. The results showed that an increase in the rate of rain by 1 mm per year will be positively reflected in an increase in pistachio productivity by 0.008 kg/tree. Similarly, the amount of irrigation water affected according to the elasticity coefficient of 0.273, while the organic fertilizer came in second place with an effect rate of 18.6%, then pesticides by 17.8%. As for the effect percentage of the main chemical fertilizers, it was about 13.4%, 11.5%, and 9.7% for each of the nitrogenous, potassium, and phosphate fertilizers, respectively. With the presence of a remarkable diversity in the cultivated varieties among four main varieties, it appears that these varieties can be classified according to the productivity averages in two distinct groups. It is the highest productivity, which included both Al-Bayadhi and Abu-Raiha cultivars, and the productivity ranged between (2850-3180) kg/ha. On the other hand, it was not found that there was a significant effect of each of the characteristics of the farms and the characteristics of the farm on the productivity of pistachios, except for the size of the farm, where the larger farms were more adequate than the small farms.
