Abstract
The research was conducted at Sit Kheris Agricultural Station in Latakia Agricultural Center, General Commission for Scientific Agricultural Research (GCSAR) in Syria, during the season 2019 in the Kiwi orchard. Three levels of drip irrigation were applied (70, 80, and 90%) of the total water requirement of plant in addition to the control (100%). The experiment executed according toRandomized Complete Block Design (RCED) with three replicates. in order to study the of water use fficiency, water consumption and scheduling irrigation, in addition to study of the effect of drip irrigation treatments on some of production characteristics of kiwi fruits. Irrigation treatments differed in their effects on the productive properties of kiwi fruits, Where the treatment 100% surpassed the other treatment in terms of diameter4.46 cm, length 6.76 cm and weight of the fruit 78.15 g, in addition to the percentage of fruit moisture 78.54%, while the treatment excelled 70% in terms of the ratio dry matter 22.3%, acids 0.59, sugars 15.05%, soluble solids 18.1%. As for the treatment, 80% outperformed in terms of water use efficiency, which amounted to 2 kg / m3, and for the average tree productivity, all treatments (80 – 90 – 100%) outperformed the treatment by 70% (9.67- 10.67- 10.3- 8.33) respectively.
Key words: Kiwi, Drip irrigation, Water requirements, Irrigation water use efficiency
