Summary
ABSTRACT Hydroponic cultivation requires proper fertigation management to avoid over‐fertigation and environmental damage. This 2‐year study evaluated the effects of full irrigation, partial root‐zone drying (PRD) and sustained deficit irrigation (SDI) on hydroponic strawberry cultivation to optimize water and fertilizer use. In the first year, various irrigation and fertilizer levels were tested, and on the basis of these results, the second year focused on full and half irrigation with different nutrient solution concentrations. This study evaluated plant morphology, physiochemical traits (e.g., chlorophyll, phenolics, and electrolyte leakage) and fruit quality (TSS/TA and L/D ratio) while calculating irrigation water productivity and biomass water use efficiency (WUE).
