This study was carried out at the rose garden established in the Deregumu region of Isparta province in Turkey in 2014. In the experiment, the effects of deficit irrigation applications with different techniques (Traditional deficit irrigation; TS: Full irrigation; GKS-75, GKS-50, GKS-25, GKS-0 and partial root zone drying; YIS:) and protection nets with different shading ratios (A: Non-covered, A-1: Shading ratio 75% and A-2: Shading ratio 35%) on the seasonal water consumption of the Isparta oil rose were determined and crop coefficient values (kc) were acquired according to the reference plant water consumption estimation method (Radiation FAO modification) that can be used in the region conditions. The highest irrigation water amount and the highest plant water consumption values were determined in the TS treatments during the experiment. Approximately % 20 and % 24.4 less irrigation water was applied to A-1: and A-2 treatments in comparison with the A treatment and similarly an average of 16 % and 17% decrease in plant water consumption was realized.
