Influence of Regulated Deficit Irrigation on Arbequina’s Crop Yield and EVOOs Quality and Sensory Profile

Regulated deficit irrigation in super-high-density (SHD) olive orchards is a well-known strategy to save water and control plant vigor, without decreasing fruit or oil yield. As there controversial information about its influence on virgin quality, trial was conducted five SHD of Arbequina cultivar different locations central, east, north northeast Spain under full (FI) regulated (RDI) treatments. RDI applied during phase II growing (40% total needs) saves more than 20% average, reductions extra (EVOO) No threshold 3.5 MPa stem potential crossed any case. modified sterols the fatty acid profile EVOOs but not phenols, quality parameters, sensory profile. Latitude, altitude, yearly rainfall have big impact some compounds such as campesterol, oleuropein, margaroleic linolenic acids.
