“…Crops growing in such an environment may be able to compensate for any early season N deficiency during the course of the growing season. Nitrogen application at the right rate leads to elevated yields by increasing the number of spikes and the number of kernels per spike (Abedi et al., 2011; Si et al., 2020). The yield improvement may take on a quadratic pattern as N rates are increased (Russenes et al., 2019; Si et al., 2020; Woodard & Bly, 1998; Yang et al., 2017), meaning that grain yield begins to decrease as applied N reaches a certain level.…”

Preplant nitrogen (N) application, which involves placing nutrients in the soil before seeding, has been an integral part of crop production systems for decades. Some producers are known to apply N at least 21 d before planting. This may increase N loss and lower grain yield. This study evaluated the effect of timing and rate of N application on winter wheat (Triticum aestivum L.) grain yield and N use efficiency (NUE). An experiment with a factorial arrangement of treatments was set up in a randomized complete block design with three replications. Treatments included four N rates (0, 45, 90, and 135 kg ha–1) with each applied 7 or 30 d before planting, and at Feekes 5 (FK5). Grain N was analyzed using LECO CN dry combustion analyzer. The difference method [Grain N from (fertilized plot – check plot)]/N applied was used to compute NUE. Nitrogen application rate significantly affected grain yield (P ≤ .01). Although the rate may be temporally and spatially variable, approximately 90 kg N ha–1 was required to obtain yields that differ markedly from the check. Mid‐season applied N (FK5) had similar yields to preplant applied N in two of four site‐years and significantly increased yield at one site in 2020. Out of two sites, the timing of N application had a substantial effect on NUE in both years (P ≤ 0.11). In this case, NUE was increased by as much as 9.5% for midseason applied N compared to 30 d before planting N application time.

“…The equal ratio treatment resulted in a higher accumulation of dry matter compared to the unequal ratio treatments, especially during anthesis. This higher accumulation of dry matter seemingly occurred because a higher abundance of assimilates at anthesis enabled plants grown under the equal ratio treatment to produce more leaves with enhanced longevity, as needed to increase the source capacity and thus, optimize leaf cover for light interception and use (Lv et al 2017;Si et al 2020). Photosynthates are produced by photosynthesis, and nutrient deficiencies at grain-filling stage can accelerate leaf senescence by increasing ROS production (Okamura et al 2018), while the supply of nitrogen fertilizer during grain-filling can delay leaf senescence and increase wheat yield (Zhang et al 2019).…”

A water-saving cultivation technique of supplementary irrigation based on soil moisture levels has been adopted for winter wheat production in the Huang-Huai-Hai Plain of China, due to the enhanced water-use efficiency. However, appropriate split nitrogen management may further improve crop growth and grain yield. Here, we conducted a 2-year field experiment to determine if split nitrogen management might improve wheat productivity by enhancing 13C photosynthate mobilization and the antioxidant defense system under water-saving conditions. Split nitrogen management involved a constant total nitrogen rate (240 kg ha−1) split in four different proportions between sowing and jointing stage, i.e., 10:0 (N1), 7:3 (N2), 5:5 (N3), and 3:7 (N4). The N3 treatment significantly enhanced “soil-plant analysis development” values, superoxide dismutase antioxidant activity, soluble protein content, sucrose content, and sucrose phosphate synthetase activity, although it reduced the accumulation of malondialdehyde (MDA). The N3 treatment ultimately increased the amount of dry matter assimilation after anthesis significantly. In addition, the 13C isotope tracer experiment revealed that the N3 treatment promoted the assimilation of carbohydrates after anthesis and their partitioning to the developing grains. Compared to the unequal ratio treatments (N1, N2, and N4), the equal ratio treatment (N3) increased grain yield by 5.70–16.72% via increasing 1000-grain weight and number of grains per spike in both growing seasons. Therefore, we recommend the use of a 5:5 basal-topdressing split nitrogen fertilizer application under water-saving irrigation conditions to promote antioxidant enzyme activity and the remobilization of photosynthate after anthesis for improving wheat grain yield.

“…Drought at the pre-flowering stage can have greater yield reductions than in post-flowering stages, because it affects yield potential at the sink level via decreasing the number of spikes m -2 as well as the number of kernels spike -1 . Mojtaba et al (2013), Mekkei and El Haggan (2014), Bashir et al (2017) and Si et al (2020) reported that decreasing number of irrigations and amount of water decreased grain yield at the different growth stages. For attaining maximum yield, moisture stress should be avoided at the time of booting and flowering stage (Ali and Sirelkhatim, 2010).…”

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.
