| Abstract | ||
| 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 (SA3) had significantly increased all the yield and its attributes traits compared to the control treatment (SA1) 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 1st 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 2nd season. Furthermore, the second order interaction I6×SA3×WC2 gave the highest value for 1000-grain weight (78.0 g) in the 1st season only. | ||
