It is very important to determine the chlorophyll content (SPAD) and nitrogen (N) requirement in order increase seed yield nutritional quality of wheat. This research was carried out with three N doses (0, 50, 100 kg ha −1 ) nine wheat cultivars (Alpu-2001, Soyer-02, Kate-A1, Bezostaja-1, Altay-2000, Müfitbey, Nacibey, Harmankaya-99 Sönmez-2001) during 2-years field condition according factorial randomized complete block design replications. In this study, dose (N50), increased by 13%, plant height 10.8%, 1,000 weight 10.5% compared control plants (N0). The from 50 gave lower rates same criteria (11.7%, 11.4%, 10.3%, respectively). However, spike number per plant, spikelet spike, length showed statistically significant differences between varieties.

Drought is the most important factor limiting winter wheat yield in North China Plain (NCP). Choosing high-yielding cultivars an measure to minimize negative effects of drought stress. Field studies were conducted with 10 2020–2022 seasons under three irrigation treatments (I0, without irrigation; I1, irrigated at jointing stage; I2, and anthesis stages) NCP examine water use strategies root shoot traits different supply conditions. The results showed that variation among was 21.2–24.6%, 23.7–25.9% 11.6–15.3% for I0, I1 I2 treatments, respectively. Under deficit conditions (I0 I1), reduced during vegetative stages increased soil reproductive stages, especially from deeper layers. Those higher length density (RLD) deep layers exhibited uptake. Each additional millimeter used after 100–200 cm grain by 23.6–29.6 kg/ha 16.4–28.5 I0 This strategy enhanced dry matter accumulation anthesis, decreased canopy temperature (CT) relative leaf contents (RLWC), which ultimately improved yield.

Conventional water and nitrogen (N) management practice in north China, comprising flood irrigation N fertilizer broadcast (FB), limits sustainable wheat production. Drip fertigation (DF) has been widely adopted production recent years effectively improved yields. However, the responses of yield quality to topdressing rate (NTR) under DF are still unclear. This study determined NTR DF, as well assessing whether could synergistically increase quality. A field experiment was conducted China for two seasons (2021–2023) using a split-plot design with three replicates. The main plot used (FB DF) sub-plot had treatment (no applied, NTRs 0, 40, 80, 120, 160 kg ha−1 150 basal fertilizer, denoted N0, T0, T40, T80, T120, T160, respectively). Our results showed that high saturated yields (12.08 11.46 t ha−1) were obtained at highest produced T160 (11.71 11.30 FB. Compared FB, greatest 10.4–12.6% achieved T80 DF. higher spike number due increased effective stem percentage greater grain weight because enhanced post-anthesis biomass (BPpost) explained radiation use efficiency (RUE) led BPpost specific leaf N, antioxidant capacity, stomatal conductance light-saturated photosynthesis flag leaves, which partly RUE. than 80 did not enhance yield, but it significantly gliadin glutelin contents, thereby leading total protein content, better gluten characteristics, superior processing Therefore, drip is practical strategy increasing both reduced input appropriate irrigated winter China.
