The influence of different irrigation rates on commercial production and fruit quality of Vitis vinifera cv. Superior Seedless was evaluated in 3-year-old vines growing on an overhead trellis (2.8 m × 2.8 m) with trickle irrigation in Pocito, San Juan, Argentina. The crop evapotranspiration (ETc) was calculated using the daily evaporation of standard class A pan. The crop coefficient was adjusted from previous research. The soil water potential with a threshold of 40 kPa determined the irrigation schedule. The treatments evaluated were 100% of ETc (1), 80% of ETc (2), 70% ETc (3), and 60% ETc (4). There was a significant difference among treatments in the number of clusters and total commercial weight, where treatments 1 and 2 had significantly higher yield than 3 and 4. The number and weight of non-commercial clusters were significantly higher in treatments 3 and 4. When water use efficiency was analysed, non-significant differences among treatments were observed. These preliminary data showed a high sensitivity of Superior Seedless to water deficits.
