The yield (t ha−1) from each plot was recorded in each pick, and the effectiveness of cucumber in using water during its complete growth period is generally described in terms of WUE and is expressed as the ratio of total crop yield to the total depth of water applied to crop including effective rainfall during its complete growth period (Steyn et al., 2000 and Oweis, 2012): WUE = CY/WA, where WUE = water use efficiency, t ha−1 mm−1. CY = total crop yield, t ha−1. WA = total depth of water applied, mm. Data on cucumber yield and water use efficiency (WUE) were recorded by using standard procedures, and were statistically analyzed. Means were separated with the LSD0.05 and LSD0.01 using GenStat 7 program.
