This study was carried out to determine the effects of different irrigation intervals and water amounts on yield and quality parameters of cut chrysanthemum. Spray cut chrysanthemum (cv. 'Bacardi') plant was used as a plant material. Class A pan was placed in the greenhouse to determine the amount of irrigation water values. Irrigation treatments consisted of three irrigation intervals (I1: 2-, I2: 4-, and I3: 6-day) and four crop-pan coefficients (kcp1: 1.20=T1, kcp2: 0.90=T2, kcp3: 0.60=T3, and kcp4: 0.30=T4). The irrigation water amounts applied to the experimental treatments ranged from 249.7 to 517.9 mm, and seasonal evapotranspiration ranged from 340.9 to 560.5 mm. Different irrigation water amounts and irrigation intervals had statistically significant effects on flower stem length, stem diameter, stem weight, the number of flowers, the vase life and root length of chrysanthemum. Stem length varied between 52.36-79.81 cm, stem diameter varied between 4.62-7.69 mm, stem weight varied between 32.48-123.61 g and root length varied between 18.88-24.22 cm. The optimum irrigation scheduling was T1I1, in which the longest flower stem and the highest stem weight were obtained.
