Two irrigation treatments, based upon a percentage of the net irrigation requirements (NIR = ETc − effectiverainfall) from 15 days after flowering until harvest, were applied:FWS and RWS at 100% (2700 m3ha−1) and 60% (1600 m3ha−1) ofNIR, respectively. The registered crop evapotranspiration (ETc) was slyghtly lower (15–20%) than the typical table grape vineyards and it was due to the moderate shading and wind reduction effect of antihail net (Kristal – Retilplast, Salerno, Italy) protection which is largely adopted in Apulia vineyards for its ameliorative effects on the yield (Rana et al., 2004).
