“…Total food yield and maize yield in the NCP accounted for 34.6 and 29.0% of the national production respectively (National Bureau of Statistics of the People's Republic of China 2014). Nevertheless, a severe water shortage is a big issue for agriculture in the NCP (Ma et al 2015). Water resources in this area only account for 7.6% of the total, and the average per capita is only one-fifth that of the nation.…”

High-temperature stress (HTS) at the grain-filling stage in spring maize (Zea mays L.) is the main obstacle to increasing productivity in the North China Plain (NCP). To solve this problem, the physiological mechanisms of HTS, and its causes and impacts, must be understood. The HTS threshold of the duration and rate in grain filling, photosynthetic characteristics (e.g., the thermal stability of thylakoid membrane, chlorophyll and electron transfer, photosynthetic carbon assimilation), water status (e.g., leaf water potential, turgor and leaf relative water content) and signal transduction in maize are reviewed. The HTS threshold for spring maize is highly desirable to be appraised to prevent damages by unfavorable temperatures during grain filling in this region. HTS has negative impacts on maize photosynthesis by damaging the stability of the thylakoid membrane structure and degrading chlorophyll, which reduces light energy absorption, transfer and photosynthetic carbon assimilation. In addition, photosynthesis can be deleteriously affected due to inhibited root growth under HTS in which plants decrease their water-absorbing capacity, leaf water potential, turgor, leaf relative water content, and stomatal conductance. Inhibited photosynthesis decrease the supply of photosynthates to the grain, leading to falling of kernel weight and even grain yield. However, maize does not respond passively to HTS. The plant transduces the abscisic acid (ABA) signal to express heat shock proteins (HSPs), which are molecular chaperones that participate in protein refolding and degradation caused by HTS. HSPs stabilize target protein configurations and indirectly improve thylakoid membrane structure stability, light energy absorption and passing, electron transport, and fixed carbon assimilation, leading to improved photosynthesis. ABA also induces stomatal closure to maintain a good water status for photosynthesis. Based on understanding of such mechanisms, strategies for alleviating HTS at the grain-filling stage in spring maize are summarized. Eight strategies have the potential to improve the ability of spring maize to avoid or tolerate HTS in this study, e.g., adjusting sowing date to avoid

“…Consequently, WUE, which is an indicator that reflects the tradeoff between water consumption and crop yield, is used widely to assess this tradeoff (Sadras and Angus, 2006;Su et al, 2007;Zhang et al, 2013a;Guan et al, 2015). In past decades, many studies have focused on the interactions among precipitation, soil water, and winter wheat yield and their effects on WUE (Huang et al, 2005;Jin et al, 2007;Ren et al, 2008Ren et al, , 2010Sun et al, 2010;Lv et al, 2013;Zhang et al, 2013bZhang et al, , 2017bMa et al, 2015;He et al, 2016).

The responses of soil water and winter wheat (Triticum aestivum L.) to changes in precipitation are crucial for stability of wheat yield and soil water conservation in the Chinese Loess Tableland Region (LTR). A 2‐yr (2014‐2016) experiment was conducted in the LTR to investigate soil water dynamics and winter wheat performance under three precipitation levels: Rc (normal), R+ (increased by one‐third of normal), and R− (decreased by one‐third of normal) by a real‐time precipitation allocation system. Soil water storage (SWS) at a depth of 0–3.8 m showed positive (R+) or negative (R−) responses to precipitation. The mean SWS in different soil layers followed an order of R+ > Rc > R−. During the experiment, the 0–3.8 m SWS decreased by 34.5 mm (R+), 183.8 mm (Rc), and 218.9 mm (R−). The shoot biomass and grain yield varied little among three precipitation levels in 2014–2015, but was reduced by 50% in R− compared with Rc in 2015–2016. The R− and Rc treatments had higher water use efficiency (WUE) than R+ in 2014–2015, and Rc was the highest in 2015–2016. The proportions of soil water to water consumption in R+ and Rc increased from 22.5% in 2014–2015 to 42.5% in 2015–2016 on average, and for R− was stable over 2‐yr (average 44.5%). Soil water plays a critical role in winter wheat performance under changes in precipitation, which should guide winter wheat production and soil water management in the future. Core Ideas Precipitation changes soil water storage but does not change the regime of soil water changing with time. Response of winter wheat yield to precipitation change has hysteresis effect. Supplementary effect of soil water compensates for the negative effect of decreased precipitation. Performance of supplementary effect is determined by precipitation pattern.

“…Fields were not irrigated and the underground water level was below five meters. If surface runoff and downward flux below the wheat root zone are ignored, the drainage at the site is negligible for soil water measurements (Ma et al 2015). Precipitation use efficiency Precipitation use efficiency (PUE) indicated the crop use efficiency of the available precipitation.…”

Soil moisture is the most critical limiting factor impacting yields of dryland winter wheat (Triticum aestivum L.) and it is strongly affected by tillage practice and sowing methods. This study was to assess the link between sowing method and tillage practice during summer fallow and their subsequent effect on soil moisture and grain yield. Furthermore, we sought to identify a more appropriate farming management practice for winter wheat production in China's Loess Plateau region. The experiment was conducted from 2011 to 2013, using a two-factor split plot design, including subsoiling (SS) or no tillage (NT) during summer fallow for main plots, and conventional drill sowing (DS) or plastic film drill sowing (FM) for subplots. Results showed that the maximum soil water storage (SWS) was under SS×FM treatment with values of 649.1 mm (2011-2012) and 499.4 mm (2012-2013). The SWS during the 2011-2012 growing season were 149.7 mm higher than that in the 2012-2013 growing season. And adoption of SS×FM significantly increased precipitation use efficiency (PUE) and water use efficiency (WUE) compared to other treatments for both seasons. Moreover, adoption of SS×FM significantly increased yield by 13.1, 14.4, 47.3% and 25.9, 39.1, 35.7% than other three treatments during the two growing seasons, respectively. In summary, combining subsoiling during summer fallow with plastic film drill sowing (SS×FM) increased SWS at sowing and effectively improved WUE, thus representing a feasible technology to improve grain yield of dryland winter wheat in the Loess Plateau of China.
