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. ...
In this research which was carried out inSuleymanDemirel University Re-search and Application Farm during 2007 and 2008 years, apple leaf area index (LAI) and leaf water potential (LWP) were observed in Jersey Mac (V1) and Wil-liams Pride (V2) young apple varieties budded on M9 rootstock irrigated with dif-ferent irrigation methods. Drip (D), subsurface drip (SD), surface (S) and under-tree micro sprinkler (M) irrigation methods were used in the research. The amount of applied irrigation water was as much as 100% of Class A Pan evaporation measured during five days irrigation intervals. The amount of irrigation water was ranged between 348.3 (D, SD) - 1186 (S, M) mm depending on irrigation methods during the experimental years. Fur-thermore, maximum and minimum crop evapotranspiration values were determined as 426.1 (DV2) and 1334.7 (MV2) mm respectively.LAI values related to treatments ranged from 0.32 to 0.52 in 2007, 0.73 to 1.12 in 2008. LAI values increased by approximately 126.3% for all treatments. In both years, generally, the highest LAI values were observed in drip irrigation (D) for both varieties. Linear correlation (r=0.99, n=16) was obtained between fruit yields and leaf area index (LAI) values of the apple trees. Leaf water potential (LWP) measurements were repeated ...
