To determine the elements of soil water balance equation during the growing season detailed description for calculating daily contribution rates to evapotranspiration of wheat (ET) from applied irrigation water (ETr) and upward flux capillarity (ETc), depth of applied irrigation water (DAIW), change in water storage (Λs) and cumulative evapotranspiration (ETcum) were algorithmed in this study. Irrigation water was applied to three different depths 30, 30-60 and 60 cm at three different depletion rates 50, 70 and 90% from plant available water. Wheat ET ranged from 428.49 to 522.12 mm. Contributions to ET from applied irrigation water ranged from 334.20 to 496.50 mm and increased with increasing irrigation depth. Contributions to ET from upward flux capillarity ranged from 25.61 to 96.59 mm and decreased with increasing irrigation depth. Contributions to ET from applied irrigation water decreased with increasing depletion rate whilst contributions to ET from upward flux capillarity increased with increasing depletion rates. Daily rate contribution to evapotranspiration from irrigation water ranged from 2.15 to 3.20 mm.d-1 and from capillary flux ranged from 0.16 to 0.61 mm.d-1.
