As irrigation management can influence crop response and water use, studies on the effect of irrigation regime on soilless cultivations may help to reduce water consumption and productive costs. The influence of different irrigation regimes on yield and quality of soilless cut roses (‘Red France’) grown in a semi-closed hydroponic system was evaluated. Three irrigation regimes (high [HIR], medium [MIR] and low [LIR]) were tested: every regime was characterized by the same duration of irrigations which were daily performed when a preset amount of accumulated radiation was reached in order to get to different total water supplies. Results showed that the low irrigation regime was more effective for soilless grown roses. There were no differences in flower yield and quality compared to medium and high regimes observed having a lower water supply and higher water use efficiency. LIR seemed to be indicated for a low-input greenhouse management of roses as it involved water and energy saving.
