The Southeastern Anatolia Region meets approximately 10% of Turkey`s pomegranate production. Siirt region pomegranate cultivation has a great importance within the region. The production of Zivzik pomegranate, a local variety of the region, was significantly increased in the last 10 years with projects and public contributions. Although there are many problems encountered in pomegranate cultivation, irregularity in irrigation programs that causes cracking in them has a significant value. In this study it was aimed to achieve the irrigation program of Zivzik pomegranate which is especially cultivated in Siirt region. The experiment was carried out in the experimental design of split plots in randomised block design with three replications, the irrigation interval was placed in the main plots, and the irrigation levels were placed in the sub-plots. Each experimental treatment was composed of 4-year-old 15 trees planted at 3x3.5 m intervals, measurements and observations were obtained from 3 trees in the middle of the block. In this study, the inline drip irrigation system was used. In the study carried out, parameters such as yield, irrigation water, plant water consumption and yield response factor were examined, and an attempt to determine the irrigation program was made. The average yield values obtained from the experiment varied between 20.5 kg/subject and 53.7 kg/subject, and no significant difference was found between the treatments as a result of the statistical analysis performed. In the subjects examined, the plant water consumption values varied between 601.5 mm and 902.9 mm, and the amount of irrigation water was determined as 292.6 mm and 585.2 mm. The yield response (Ky) showing the sensitivity of pomegranate to water deficiency was calculated as 1.59.
