“…Our study showed that compared to JM and LX, additional consumption of 22.7-44.6 mm soil water after anthesis in YN increased grain yield by 960-2797 kg ha −1 (Figures 1, 5). The WUE in YN were 6.0% and 10.8% higher than in JM, respectively, and 17.3% and 25.3% higher than in LX, respectively, in 2017LX, respectively, in -2018LX, respectively, in and 2018LX, respectively, in -2019 Besides producing the same grain yield from less water resources, an increased WUE in crop production can also be achieved through increased grain yield by cultivar replacement (Zhang et al, 2017;Yan et al, 2021). In this study, the increase in WUE of YN was attributed to the increased grain yield, because YN increased SWC AM and obtained the highest ET C (Figure 1 and Table 1).…”

Selecting high-yielding wheat varieties for cultivation can effectively increase water use efficiency (WUE) in the Huang–Huai–Hai Plain, where is threatened by increasing water shortages. To further identify the difference in water use and its relationship with root morphology and senescence characteristics, wheat varieties with different yield potentials—Yannong 1212 (YN), Jimai 22 (JM), and Liangxing 99 (LX)—were studied in a high-yielding wheat field. The water consumption percentage (CP) in YN decreased from planting to anthesis; however, crop evapotranspiration and CP increased from anthesis to maturity compared with JM and LX. In YN, a higher soil water consumption from anthesis to maturity in the 0–100 cm soil layer was partly attributed to the greater root weight density in the 20–60 cm soil layer. In topsoil (0–40 cm), root length density, root surface area density, and root diameter at 20 days after anthesis, root superoxide dismutase activity, and root triphenyl tetrazolium chloride reduction activity during mid grain filling stage were higher in YN than in JM and LX. YN had the highest grain yields of 9,840 and 11,462 kg ha–1 and increased grain yield and WUE by 12.0 and 8.4%, respectively, as compared with JM, and by 30.3 and 21.3%, respectively, as compared with LX. Ensuring more soil water extraction post-anthesis by increasing roots in the 20–60 cm soil profile, improving root morphology traits, and alleviating root senescence in the topsoil during mid-grain filling stage will assist in selecting wheat varieties with high yield and WUE.

“…Foxtail millet (Setaria italica L.), a member of the Poaceae family, is one of the world's oldest domesticated crops [30]. It has gained significant attention in recent years because of its unique drought-resistant characteristics, adaptability, and high water-utilization efficiency; hence, it is the primary crop promoted for green development in Northern China's arid land ecological agriculture [31][32][33][34]. As a traditional coarse grain in China, foxtail millet is highly valued for its nutritional content, which includes abundant micronutrients including calcium, iron, and zinc, as well as its pleasing taste and texture [35][36][37].…”

Foxtail millet is highly valued in China; however, its optimal fertilization parameters are unknown. This study investigated the effects of nitrogen (N), phosphorus (P), and potassium (K) fertilizer combinations on foxtail millet agronomic traits, photosynthetic characteristics, yield, and quality to promote rational fertilizer application. Pot experiments were conducted using the “3414” fertilizer effect scheme and the representative crop variety was JG21, containing four NPK levels and 20 replicates per treatment, individually. The effects of N, P, and K levels on agronomic traits were analyzed during the jointing, heading, and filling stages. JG21 performed optimally under treatment with N160P90K150 (T6); the yield and fat content increased by 49.32% and 13% compared to the control. Correlation analysis revealed that N was significantly positively (negatively) correlated with the protein (amylose) content. P was significantly positively correlated with the fat and moisture content and K was correlated with the moisture, fat, and protein content, but was negatively with the amylose content. Overall, rational ratios of NPK fertilization improved foxtail millet yield and quality. Based on fuzzy comprehensive evaluation, the T6 treatment (N160P90K150) demonstrated the highest comprehensive effect among 13 NPK fertilizer combinations. Rational application of NPK in foxtail millet may improve agronomic performance by enhancing leaf photosynthetic efficiency and aboveground biomass accumulation.
