^a SDI utilized 80% ET_c from bud-break to harvest, for RDI utilized 80% ET_c from bud-break to fruit set, 50% ET_c from fruit set to veraison, and 80% ET_c from veraison to harvest. ^b Irrigation was not applied before the leaf water potential reached −1 MPa. Hence, there was no water applied prior to fruit set in 2015.
