Table 1 Probability levels from the analysis of variance (ANOVA) for seasonal evapotranspiration (ET), water productivity (WP), fallow precipitation storage efficiency (PSE), soil water storage during the summer fallow season (SWS), grain yield, evapotranspiration (ET), water use efficiency of wheat (WUE), soil water depletion during the wheat growing season (SWD), and soil water balance (SWB) at a depth of 0–200 cm.
