“…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). The texture of the soil studied by Guan et al (2015) was light loam, whereas Huang et al (2012) studied silty loam soil.…”

“…In addition, Licht and Al-Kaisi (2005) observed that SMC had no effect among tillage methods. NT showed a higher degree of soil compaction in the 0-20 cm topsoil layer and reduced root growth, especially at deeper soil levels (Kan et al 2020). NT reduced the wheat crop yield mainly because of a reduction in 1 000-grain weight and the number of panicles produced per unit area (Guan et al 2015).…”

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.

“…As the largest wheat producer and consumer in the world, wheat production in China is crucial for local markets and for the global wheat industries [4]. In particular, the North China Plain (NCP) is playing an important role by producing over 50% of the national wheat harvest [5] from only 21% of the total wheat acreage in China. Thus, stability and improvement in wheat grain yield in NCP are very important for national food security, as well as for global food supply chains.…”

For improving lodging resistance and increasing grain yield in wheat in the Yellow-Huai River Basin in China, different sowing modes have been investigated. Conventionally, the small-flat-plot sowing mode has been adopted in wheat cultivation. However, this sowing mode leads to heavy lodging and low land use efficiency. In this study, a new sowing mode, high-low-plot sowing mode with two more rows sowed on the high plot, was investigated. Two cultivars, Hengguan 35 and Jimai 44 were used for two seasonal field experiments from 2018 to 2020. The results showed that grain yield improved with the high-low sowing mode by as much as 25% since more spikes per unit area were observed concomitant with reduced stem lodging. The grain yield increase was mainly due to the enhanced spike number per m2, while the lodging resistance was improved through the lowered plant height and the center of gravity height. This research proves that the high-low-plot sowing mode is an improved sowing mode for producing greater grain yield with better lodging resistance in the wheat production area in northern China.

“… Wang et al (2012) showed that NT was beneficial to increasing the contents of soil aggregates, thereby increasing soil nutrients; however, it was suggested that years of NT would increase soil compactness and reduce crop yields. Here, NT resulted in the lowest maize yield and it was found that long-term NT could cause soil hardening and increases in bulk density ( Kan et al, 2020a ), affecting the development of crop root systems, as well as nutrient and water absorption, which may be why the lowest yields were recorded with NT in this study ( Ren et al, 2018 ).…”

Background Soil degradation is one of the main problems in agricultural production and leads to decreases in soil quality and productivity. Improper farming practices speed this process and are therefore not conducive to food security. The North China Plain (NCP) is a key agricultural area that greatly influences food security in China. To explore the effects of different tillage measures on aggregate-associated organic carbon (AOC), the accumulation and transport of dry matter, and maize yield, and to identify the most suitable tillage method for use on the NCP, a field experiment was conducted at Shandong Agricultural University from 2016–2017 using plots that have been farmed using conservation tillage since 2002. Methods In this study, Zhengdan 958 summer maize was used as the test material and undisturbed soil and plant samples were obtained under four tillage methods—no-tillage (NT, tillage depth: 0 cm); rotary tillage (RT, tillage depth: 10 cm); conventional tillage (CT, tillage depth: 20 cm); subsoiling (SS, tillage depth: 40 cm)—which were used to determine the AOC and dry matter contents, as well as the yields of two summer maize growing seasons. Each sample was replicated three times and the AOC content was determined via potassium dichromate oxidation colorimetry. Potassium dichromate oxidized organic carbon in organic matter was employed to reduce hexadecent chromium into green trivalent chromium. Colorimetry was then used to determine the amount of reduced trivalent chromium and calculate the organic matter content. Results The resulting data were statistically analyzed and the results showed that, compared with CT, the AOC contents with NT and SS increased by 5.65% and 9.73%, respectively, while that with RT decreased by 0.12%. Conventional tillage resulted in the highest mean dry matter weight when the maize reached maturity, which was 19.19%, 9.83%, and 3.38% higher than those achieved using NT, RT, and SS, respectively. No significant difference was found between CT and SS treatments, both of which tended to increase the accumulation of dry matter as well as its contribution of assimilates to grain yield post-anthesis. Compared with CT, the mean yield increased at a rate of 0.18% with SS, while yields declined at rates of 17.17% and 11.15 with NT and RT, respectively. The yield with NT was the lowest, though the harvest indices with NT and SS were higher than those with RT and CT. Overall, SS increased the accumulation of dry matter and its contribution of assimilates to grain yields post-anthesis, as well as the AOC content and yields, making it the ideal tillage method for the NCP.
