“…NT enhanced total soil water storage in the 0-150 cm soil profile, mainly because of the increase in mean root weight density under NT (Huang et al 2012). However, Guan et al (2015) indicated that NT inhibited root growth (root length density, root surface area density, and root weight density) and decreased leaf area index (Liu et al 2020), whereby evapotranspiration was reduced. Similar results were reported by Kan et al (2020).…”

“…Specifically, evapotranspiration was lower in G1 than in G2 by 7.57, 6.37, 6.26, and 3.45%, under NT, and by 11.09, 9.46, 4.24, and 3.06%, under T, in the successive experimental cropping seasons, respectively. Winter wheat genotypes with higher tillering capacity and tiller formation rate tend to develop a larger number of spikes per unit area (Liu et al 2020), resulting in larger plant populations. Plant population and water consumption correlate positively under suitable conditions.…”

“…Overall, grain yield was significantly decreased (6.79, 11.99, 14.78, and 15.73%, respectively) for NT relative to T. We believe that numerous factors affected yield under various tillage methods. Thus, for example, NT can significantly decrease light radiation interception by the upper canopy (Liu et al 2020) and reduce temperature, which might affect leaf area and biomass accumulation (Liang and Richards 2012). Together, these effects might partly explain the decrease in grain yield in NT plots.…”

“…He et al (2007) indicated that four consecutive years of NT practice followed by one year of subsoiling might mitigate the increasing level of soil compaction resulting from NT. The reason for the reduction of grain yield and WP under NT over the years may be the reduction in spike number (Liu et al 2020) due to the increase in soil compaction, which in turn likely limits root growth and, consequently, plant access to soil water and nutrients.…”

Uneven distribution of precipitation and overexploitation of groundwater resources threatens the sustainability of agriculture in the North China Plain. Adoption of water deficit-tolerant winter wheat genotypes coupled with timely, adequate farming practice is crucial to enhance sustainable crop production and water productivity in the region. The present study aimed to evaluate water consumption patterns and water productivity of two winter wheat genotypes (Tainong-18 and Jimai-22), under no-tillage or conventional tillage, over a period of four consecutive cropping seasons. Under no-tillage, Tainong-18 showed the lowest soil moisture consumption before sowing in the 30–110 cm soil profile. Jimai-22 under conventional tillage and Tainong-18 under no-tillage showed the highest and lowest evapotranspiration across cropping seasons, respectively. Compared with conventional tillage, no-tillage reduced grain yield and water productivity of winter wheat, and the difference between them increased for grain yield (6.79, 11.99, 14.78, and 15.73%) and water productivity (0.99, 8.14, 12.18, and 13.30%) over the 2015–2016, 2016–2017, 2017–2018, and 2018–2019 cropping seasons, respectively. In contrast, Tainong-18 showed lower evapotranspiration and increased grain yield and water productivity compared with Jimai-22. Further, Tainong-18 showed a compensatory effect on the reduction of water productivity under no-tillage, compared with Jimai-22. Our conclusions indicate that the combination of no-tillage and water-efficient winter wheat genotypes is an effective strategy to offset the reduction in water productivity caused by no-tillage and thus maximise water productivity in the North China Plain.

“…The responses of different ecosystems to agronomic management practices vary ( Brouder & Gomez-Macpherson, 2014 ). In general, the reasons for crop yield losses under NT are plant diseases ( Wang et al, 2020 ), lower flag leaf fluorescence parameters and leaf area index ( Liu et al, 2019 ), and reduction of spike numbers ( Ren et al, 2018b ). Winter wheat spike numbers were lower in NT than in T in this study.…”

Background Implementing sustainable farming practices for winter wheat (Triticum aestivum L.) in the North China Plain may be a way to reduce carbon emissions. No tillage generally results in less net CO2 loss from farmland, but no tillage also reduces the grain yield and water use efficiency (WUE) of winter wheat. Wide-precision planting of winter wheat may enhance the grain yield and WUE; however, it is not known precisely how tillage and planting patterns affect CO2 exchange, grain yield and WUE. Methods In this study, two tillage methods (conventional tillage, T and no tillage, NT) and two planting patterns (conventional planting, C and wide-precision planting, W) were used in two consecutive winter wheat growing seasons. Results Compared with the T treatments, the NT treatments had significantly lower cumulative net CO2 emissions in 2015–2016 and 2016–2017 (30.8 and 21.3%, respectively), and had lower grain yields (9.0 and 9.4%, respectively) and WUE (6.0 and 7.2%, respectively). The W treatments had a compensating effect on grain yield failure and reduced cumulative net CO2 emissions more than C treatments, thereby increasing WUE, reducing carbon emissions per unit water consumption, and increasing the yield carbon utilization efficiency (YCUE). The lowest cumulative CO2 emissions and highest YCUE were observed for NT with W treatment. Results from this analogous tillage experiment indicated that NT and W farming practices provide an option for reducing carbon emissions and enhancing WUE and YCUE for sustainable winter wheat development.
