Effects of different irrigation regimes on yield and water use efficiency of cucumber crop

The results indicated that the 70% ETc treatment obtained the highest crop yield followed by ETc, FI, and TI treatments, respectively. On average, cucumber yield under 70% ETc treatment was 24%, 6% and 4% higher than that under TI, FI and ETc treatments, respectively. At the end of harvesting stage plant height, above-ground dry matter obtained by 70% ETc treatment was higher than the other treatments. The smallest plant height and dry matter was obtained under TI treatment. Results also indicated that, when using scheduled irrigation methods large amount of water were saved and found to be 139, 104 and 26 mm for TI, 70% ETc and ETc treatments, respectively, compared to FI treatment. The highest water use efficiency (WUE) was obtained under 70% ETc treatment followed by ETc, TI and FI treatments, respectively.
