“…Kotb et al, (2021) cleared that irrigation 6 times significantly resulted in increased spikes number m -2 , 1000-grain weight, and grain yields of wheat compared with the plots irrigated 4 times. The maximum values for plant height, number of spikes m -2 , number of grains spike -1 1000-grain weight, flag leaf area, and grain yield were obtained from wheat plants that received four irrigations compared to plants irrigated twice across the growing seasons (El-Nagar and EL-Gohary, 2022). Improving WUE in the crop production sector includes improving land cultivation, developing droughttolerant genotypes, and applying special agriculture practices (El-Hendawy, 2016).…”

In the present study, we estimated the yield and its attributes as well as water use efficiency of two bread wheat cultivars, i.e., Shandaweel-1 and Giza-171 under three irrigation intervals, i.e., irrigation every 6, 9 and 12 days, and three concentrations of salicylic acid, i.e., 0.0, 150, and 300 ppm which was done at a private farm in the village of Al-Ghuraira, Esna center, Luxor governorate upper Egypt during 2018/2019 and 2019/2020 seasons. This study was laid out in a strip-split plot arrangement was based on a randomized complete block design (RCBD) with three replications. The results indicated that increasing irrigation intervals (I) from 6 up to 9 or 12 days significantly decreased vegetative traits, yield and yield attributes traits, i.e., plant height, flag leaf area, spike length., number of kernels spike -1 , kernels weight spike -1 , 1000-grain weight as well as grain yield fed. -1 , but significantly increased grain protein content (%), water use efficiency (WUE) and water saving% in both seasons. The Foliar application of 300 ppm of salicylic acid (SA 3 ) had significantly increased all the yield and its attributes traits compared to the control treatment (SA 1 ) As well as improving WUE under the conditions of irrigation periods every 9 and 12 days. Shandaweel-1 cultivar outperformed Giza-171 cultivar in plant height, spike length, grain yield and WUE in both seasons, and number of kernels spike -1 in the 1 st season. Likewise, Giza-171 surpassed Shandaweel-1 in flag leaf area, kernels weight spike -1 , 1000-grain weight and protein% in both seasons, and number of kernels spike -1 in 2 nd season. Furthermore, the second order interaction I 6 ×SA 3 ×WC 2 gave the highest value for 1000-grain weight (78.0 g) in the 1 st season only.
