“…Moreover, water stress imposed at post flowering reduced the grainfilling period hence decreased days to maturity. These results are in line with those obtained by Menshawy et al (2006), Mekkei and El Haggan (2014) and El-Hag (2017) who reported that skipping irrigation at elongation, booting and flowering stage decreased number of days to maturity.…”

“…Mekkei and El Haggan (2014) reported that skipping irrigation at elongation and initiation of booting stage decreased days to heading. Also, Menshawy et al (2006) and El-Hag (2017) reported that decreasing number of irrigation caused early heading.…”

“…Under scarcity of water, four irrigations scheduled at crown root initiation, tillering, flowering and milky stages saved two irrigations without significant yield loses (Ahmad and Kumar, 2015).The highest values of growth characters were obtained with five irrigations at crown root initiation, tillering, jointing, flowering and milking stages (Banker et al, 2008).Water stress through withholding irrigation at the ear emergence and grain filling phases reduced grain yield and its components as will as relative water content (Zarein et al, 2014). Decreasing number of irrigations decreased days to heading, days to maturity, plant height, number of spikes m -2 , number of grains spike -1 and 1000-kernel weight, grain yield, biological yield, and straw yield (El-Hag, 2017 andSeleiman andAbdel-Aal, 2018). According to many researchers, membrane stability index and relative water content are good physiological indices of drought tolerance and can be used for improving drought tolerance in wheat (Almeselmani et al, 2011).Water stress applied at different growth stages of wheat plant decreased leaf relative water content and membrane stability index (Akram, 2011, Mahmoud, 2015and Abd El-hady et al, 2018.…”

Field experiments were conducted at Shandaweel Agric. Res. Station, Sohag, Egypt, during the two growing seasons 2018/2019 and 2019/2020 to study the effect of six irrigation regimes, i.e. I1 (irrigation at tillering and elongation stage), I2 (irrigation at tillering and flowering stage), I3 (irrigation at tillering, elongation and flowering stage), I4 (irrigation at tillering, booting and grain filling stage), I5 (irrigation at tillering, elongation, booting and flowering stage) and I6 (irrigation at tillering, elongation, booting, flowering and grain filling stage) on some agronomic and physiological traits of four wheat cultivars, i.e.Shandaweel1, Sids 14, Sohag 4 and Sohag 5. Results showed that decreasing number of irrigations and amount of applied water at different growth stages significantly decreased all studied traits. The highest reduction was recorded under I1 (1432 m-3 ha-1) for all studied traits, except days to heading and number of spikes m-2. Meanwhile, the lowest reduction was observed under I5 (3088 m-3 ha-1) for all studied traits as compared to I6 (3965 m-3 ha-1 of applied water). Irrigation at both booting and flowering are essential to reduce loss in grain yield. Moreover, Sids 14 exhibited lower yield reduction under different irrigation regimes, while sohag 4 and Sohag 5 exhibited the highest yield reduction. Therefore, Sids 14 proved to be drought tolerant cultivar, while Sohag 4 and Sohag 5 were drought sensitive. Planting Sids 14 cultivar with irrigation at tillering, booting, grain filling stages (I4) are useful to save about (36.97%) of applied water without significant decrease in grain yield.

Similar trend was observed by Gheith et al (2013); Noureldin et al (2013); Fergani et al (2014); Elhag (2017) and Farag et al (2018). On the contrary, these results conflicted with those obtained by Hassanein et al (2018).…”

A field experiment was carried out during 2016/ 2017 and 2017/ 2018 seasons at the Agronomy Department Experimental Farm, Agriculture Faculty, Assiut University to study the effect of foliar spray time by different zinc oxide nanoparticles sizes on productivity and quality of some bread wheat cultivars. The experiment was laid out in randomized complete block design (RCBD) using split plot in strips arrangement with three replications. Zinc dioxide nanoparticles size (control, 20.7, 23.0 and 27.0 nm) were allocated horizontally, while, the three bread wheat cultivars (Sids-1, Sids-12 and Gemmeaza-11) were arranged vertically and zinc spray time (30, 45 and 60 days after planting) were assigned in sub plots. The obtained results show that the zinc oxide nanoparticles sizes (ZnO NPs), bread wheat cultivars and zinc spray time variables had a significant influence on all studied traits in the two growing seasons except the effect of zinc application time on number of spikes m -2 and grain yield feddan -1 traits in the first season which was non-significant. In addition, the most first order interactions had a significant effect on most studied traits in both seasons. Furthermore, the second order interaction had a significant effect on all studied traits in both seasons. The highest mean values of grain yield feddan -1 (28.67 and 28.50 ardab feddan -1 in the first and second seasons, respectively) were obtained from planting Gemmeza-11 cultivar and sprayed it by minimum size (20.7 nm) of ZnO NPs after 60 days from planting. Moreover, sowing Sids-12 cultivar and sprayed it by minimum ZnO NPs size (20.7 nm) at 30 days after planting recorded the maximum mean value of grains dry gluten content (13.72 %) in the first seasons, while, the highest mean value of grains dry gluten content (14.37 %) in the second seasons was achieved from planting Sids-1 cultivar and sprayed it by minimum ZnO NPs size (20.7 nm) at 60 days after planting.

“…Cultivars and fertilization significantly influenced grain yield and quality of wheat grain production. The differences among wheat cultivars were recorded by Seadh (2014), EL-Hawary and Shahein (2015), Anwar et al, (2016), El-hag (2016), Kandil et al, (2016), El-hag (2017) and El -Hag and El Mantawy (2017). These differences due to genetic back ground or the interaction with environmental condition.…”

Two field experiments was carried out at the Experimental Farm of Faculty of Agriculture, Kafrelsheikh University -North Nile Delta, Egypt, during the two successive winter seasons of 2014/2015 and 2015/2016, to investigate the effect of different nitrogen rates (60, 120, 180 and 240 kg N/ha) and phosphorus rates (0, 36 and 72 kg P 2 O 5 /ha) on yield and yield attributes of two bread wheat cultivars (Misr 2 and Giza 168) grown on clay soil conditions. Misr 2 was higher than Giza168 in values of number of days to heading, plant height, number of fertile tillers in both seasons and number of grain /spike, biological yield, grain yield and straw yield in the first season. Giza 168 recorded the highest values for 1000 grain weight and harvest index in the first season. Fertilizing with 240 kg N/ha resulted the highest values of yield attributes and significantly exceeded other studied levels (60, 120 and 180 kg N/ha). Application of 240 kg N/ha recorded the highest values of grain and straw yields (7.430 and 6.514 t/ha) and straw (12.071 and 10.119 t/ha) in the first and second seasons, respectively. P 2 O 5 had significant effect on most characters under this study. Increases P 2 O 5 rates increased all traits except heading date and harvest index, where the inverse was true P 2 O 5 . Fertilizing with 72 kg P 2 O 5 /ha resulted the highest values of grain yield (6.564 and 6.749 t/ha) and straw yield (10.110 and 11.062 t/ha) in both seasons. Respectively. Fertilizer with 240kg N/ha and 72 kg P2O5/ha recorded the highest values for all traits in both seasons.
