Regulated Deficit Irrigation (RDI) via drip systems can reduce vegetative growth, potentially delay flower initiation, and reduce vase life in rose and gerbera under protected cultivation by applying controlled water stress, especially during flowering stages. The specific timing of the water deficit is crucial, as stress applied during later, reproductive, or flowering stages can be more detrimental to quality and vase life than stress applied during early vegetative growth. Regulated Deficit Irrigation can improve water-use efficiency and stress tolerance, growers must carefully balance water savings with the risk of reduced flower yield and post-harvest longevity.
