“…Under the minimum irrigation strategy, sustainable groundwater use could be achieved, but with up to 20% yield penalties. These and other studies (Ali et al., 2019; Araya et al., 2019; Farooq, Hussain, Ul‐Allah, & Siddique, 2019) have demonstrated that irrigation strategies can be effective options for resolving water shortage problems around the world, but it usually comes at the expense of yield.…”

North China Plain farmers often use maize (Zea mays L.) silage for dairy cows. Double cropping of maize may be a feasible way to reduce annual water use and land required to produce feed. The objective of this study was to evaluate the possibility of growing a double crop of silage maize with and without plastic film mulch. An experiment was conducted between 2015 and 2018 and contained three treatments: double-cropped (maize) plastic film mulch (2 M+PM), double-cropped (maize) without plastic film mulch (2 M), and double-cropped winter wheat (Triticum aestivum L.) and summer maize (WW+SM). Net income, yield, water use efficiency (WUE), and annual water use were determined. The results indicated that silage dry matter yield and WUE were improved by 45.6 and 31.5%, respectively, using plastic film mulch compared with no mulch. Total water footprint in producing the silage was also reduced by 24% using plastic film mulch. The annual water use was reduced by 150-190 mm with 2 M+PM or 2 M compared with WW+SM. Average net income was 429, 926, and 1,008 $ ha −1 in 2 M, 2 M+PM, and WW+SM, respectively. The results indicated that the advantages of the double-silage maize system lie in the reduction in the amount of land required to produce maize silage for dairy cows. However, due to the limited growth duration for the double maize, high silage water contents reduced silage quality. 1 INTRODUCTION The consumption of animal products in developing countries has increased by approximately 5-6% annually since 2000 (Ingersent et al., 2003).

“…However, Fang et al (2021) reported that in the semi-arid region on the Loess Plateau, modern wheat varieties with yields between 5,814 and 6,115 kg ha −1 had less root biomass and root length density in the 0-40 cm soil layer, which reduced pre-anthesis water uptake but increased soil water extraction after anthesis, contributing to the increases in grain yield and WUE. Regulating root morphology characteristics by irrigation technologies can influence the uptake of soil water during the post-anthesis phase, that have major effects on wheat yield and WUE (Ali et al, 2019). However, the onset of wheat senescence during post-anthesis is inevitable (Nehe et al, 2020).…”

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.

“…Studies have shown that the application of 75 mm of irrigation water during jointing and anthesis is the best irrigation strategy in the North China Plain, and it is believed that one irrigation event at the jointing stage can be used as an alternative irrigation mode to reduce irrigation and maintain the sustainable development of farmland water resources 13 . In semi-arid areas, the ridge-furrow rainfall harvesting system combined with 75 mm of irrigation increases soil moisture across the rooting area, making it a high-yield and efficient water-saving strategy 14 .…”

In lime concretion black soil, a two-factor (tillage and irrigation) split block experiment from 2015 to 2017 was conducted to identify whether their combination is suitable for the improvement of winter wheat yield and water use efficiency. The main treatments were subsoiling (SS) and rotary tillage (RT), with secondary treatments of three irrigation regimes: no irrigation during the whole growth period (W0), irrigation at jointing stage (W1), and irrigation at both jointing and anthesis stages (W2). In combination with a soil column experiment, the contribution of the root system in different soil layers to yield was clarified. The results indicated that both tillage and irrigation significantly influenced the spatiotemporal distributions of the root systems and yield components, while tillage produced the strongest effect. Compared with RT, SS significantly promoted the root penetration and delayed root senescence in deep soil layers. With increasing soil depth, each root configuration parameter (dry root weight density, DRWD; root length density, RLD; root surface area per unit area, RSA; root volume per unit area, RV) gradually decreased, and the peak appearance times of each root parameter in RT and three parameters (RLD, RSA and RV) in SS were postponed from heading to anthesis and from anthesis to filling stage, respectively. The average post-peak attenuation values at soil layers from 60 to 100 cm in W1 were less than those in W0 and W2. SSW1 generated the highest grain yields, with an average increase of 31.88% compared with the yield in RTW0. Root systems at three soil layers (0–40 cm, 40–80 cm and below 80 cm) differentially contributed to grain yields with 78.32%, 12.09% and 9.59%, respectively. The growth peak of the deep root system in SSW1 was postponed to the filling stage, and the post-peak attenuation declining rates were also slowed. Therefore, SSW1 is an effective cultivation method improving grain yields and water use efficiency in lime concretion black soil.
