  1. CRWU: cumulative root water uptake; CE: cumulative evaporation; CDD: cumulative deep drainage; SWC Initial: Initial (on the first day of simulation) cumulative soil–water content (mm) in soil profile up to 45 cm depth; SWC Final: Total soil water content in 45 cm depth of soil on the last day (82th) of simulation; CVF: cumulative variable flux; CI: cumulative infiltration (rainfall + irrigation) for treatments with furrow irrigation and only rainfall for treatments with subsurface drip irrigation; SWB: soil water balance.
