“…S3 and S4), which implies that further increases in these parameters through plant breeding and crop management strategies could increase stem strength and lead to stronger stem lodging resistance. This is also in alignment with previous reports that stem diameter and flexural rigidity of basal internode could be used as an important criteria for future variety improvement with robust stem breaking resistance (Liu et al., ; Niu et al., ; Wu & Ma, ; Zhang et al., ).…”

“…As we speculated for WW practice, greater soil moisture because of irrigation led to decreasing soil shear strength for loamy clay soil of this study that made plants more prone to root lodging, compared with RFPFM and FP, as has been reported elsewhere (Pinthus, ). Several studies have already indicated that root lodging is more prevalent than stem lodging under irrigated conditions or in humid environment regions (Berry, Sterling, Baker, Spink, & Sparkes, ; Wu & Ma, , ). Under RFPFM, favorable hydrothermal conditions could further ensure healthy root growth and a stronger crown root architecture system that maintains and spreads a widened root–soil cone, increases anchorage strength (Bian et al., ; Wu & Ma, ; Wu et al., ) and root‐lodging resistance, compared with other planting patterns.…”

“…This is because the improved soil hydrothermal conditions led to taller plants and increased risk of lodging, due to greater gravitational force and bending momentum (Li et al., ; Peng et al., ; Tripathi, Sayre, Kaul, & Narang, ). Meanwhile, stem morphological parameters such as stem diameter, length of internode, stem wall thickness and mass density that are strongly correlated with the stem mechanical traits such as stem breaking resistance, bending stress, Young's modulus and flexural rigidity, may also be altered due to the favorable soil hydrothermal characteristics under RFPFM practice (Kong et al., ; Liu, Ma, Zhao, & Zhou, ; Wu & Ma, ). Therefore, we hypothesized that the increase in attainable yield under RFPFM may require considerable improvement in stem‐lodging resistance to counter the escalating risk of lodging.…”

Ridge-furrow with plastic film mulching (RFPFM) is widely used as a water-saving strategy for the improvement of crop yield. However, lodging susceptibility under RFPFM practices has not yet been determined. A 2-yr field study comprising of three cultivation strategies (rain-fed flat planting [FP], RFPFM, and well-water planting [WW]) and two N application rates (75 and 225 kg N ha -1 ) was conducted to assess the risk of lodging and the relationship between lodging resistance and grain yields of two wheat (Triticum aestivum L.) varieties (Xinong979 as lodging resistant and Xiaoyan22 as lodging susceptible). The results showed that higher N application increased lodging index under FP and RFPFM, and the lodging index was 33% lower under RFPFM than under WW. In both years, there was a positive relationship between grain yield and lodging susceptibility (R 2 = 0.62** and 0.57**) implying that promoting crop yield by using RFPFM strategy accelerates the risk of lodging. When compared with WW, RFPFM significantly reduced the lodging index, while sustaining a comparable grain yield. Overall, RFPFM could be highly recommended as a promising strategy for winter wheat producers in dry, semi-humid regions. The close relationships of breaking resistance and lodging index with both mass density and stem wall thickness of basal internode suggest that selection for increased stem strength trait could lead to improved lodging resistance and higher yields in future programs for winter wheat cultivar improvement.Abbreviations: BM, bending moment; DAS, days after sowing; FP, rain-fed flat planting; LAI, leaf area index RFPFM, ridge-furrow with plastic film mulching; WW, well-water planting.

“…Although, the term, sustainability, has moved from a conceptualization to the improvement of analytical tools, anthropogenic interruptions are leading to increases in growing ecological tremors [22]. Long-term sustainability is one of the ultimate goals that improves the overall performance of agricultural systems and reduces threats to the health of humans and ecosystems [23,24]. According to Godfray et al [1], the theme of sustainability is based on the phenomenon that resources should not be used at rates higher than the capability of the Earth to substitute them.…”

The rising population and reduction in the amount of land and some other resources have created tremendous pressure on current agricultural producers to meet the increasing food demands. To cope with this challenge, certain key inputs, such as fertilizers and other chemicals, are overused, which are worsening the surroundings. This intensive agricultural production without adherence to ecological sustainability has led to declining soil health, land degradation, and severe environmental problems. So, future efforts to feed the growing population should aim for greater agricultural production within sustainable environments. In this regard, innovative steps are needed, as business-as-usual policies lack the potential to cope with these challenges. The concept of agricultural sustainability and various soil and crop management strategies (SCMS) that have been designed to optimize crop yield under sustainable environmental conditions are discussed, including nutrient management, site specific nutrient management (SSNM), integrated nutrient management (INM), integrated soil fertility management (ISFM), integrated soil-crop system management (ISSM), ridge-furrow mulching systems (RFMS), sustainable water management (SWM), conservation agriculture (CA), sustainable land management (SLM), vertical/sky farming, and integrated crop management, and breeding strategies as well as other approaches combined with technological and behavioural changes. The present review suggests that a sustainable production system can be developed by combining the multifaceted efforts under SCMS practices with short- and long-term preventive measures. Reducing chemicals’ usage, such as that of fertilizers and pesticides, plus improvements in the crop input use efficiency could minimize greenhouse gases emissions while protecting the environment. Sustainable agriculture holds promise for humankind and the planet Earth, and it can be successful if all developed and developing nations stand together to seek ‘our common future’ to produce more food while generating less environmental pressure.

“…In this region, N fertilizer is vulnerable to loss during the growing season by volatilization, denitrification, surface runoff, and leaching ( Ma et al., ; ; ), such that N availability may limit canola growth and yields ( Ma et al., ). Applying N fertilizer in excess of canola requirements is contraindicated because this practice increases production costs, induces canola crop lodging, reduces seed yield and quality, and increases N losses from the agroecosystem ( Rathke et al., ; Wu and Ma , ; ). Expansion of canola production in eastern Canada is highly dependent on the development of regional or site‐specific guidelines for environmentally‐sound N management that focus on improving N fertilizer use efficiency ( Ma and Herath , ).…”

Balanced plant nutrition is essential to achieve high yields of canola (Brassica napus L.) and get the best economic return from applied fertilizers. A field study was conducted at nine site‐years across eastern Canada to investigate the effects of nitrogen (N), sulfur (S) and boron (B) fertilization on canola nutrient uptake, nutrient balance, and their relationship to canola yields. The factorial experiment consisted of four N rates of 0 (N0), 50 (N50), 100 (N100), and 150 (N150) kg ha−1, two S rates of 0 (S0) and 20 (S20) kg ha−1, and three B treatments of 0 (B0), 2 kg ha−1 at preplant (B2.0P), and 0.5 kg B ha−1 foliar‐applied at early flowering stage (B0.5F). Each site‐year used the same experimental design and assigned treatments in a randomized complete block design with four replications. Fertilizer S application greatly improved seed yields at six out of nine site‐years, and the highest N use efficiency was in the N150+S20 treatment. Sulfur application generally increased seed S concentration, seed S removal, and plant total S uptake, while B fertilization mainly elevated straw B concentration and content, with minimal effect on seed yields. At the early flowering stage, plant tissue S ranged from 2.2 to 6.6 mg S g−1, but the N : S ratio was over or close to the critical value of 12 in the N150+S0 combination at five site‐years. On average across nine site‐years, canola reached a plateau yield of 3580 kg ha−1 when plants contained 197 kg N ha−1, 33 kg S ha−1 and 200 g B ha−1, with a seed B content of 60 g B ha−1. The critical N, S, and B values identified in this work and their potential for a posteriori nutrient diagnosis of canola should be useful to validate fertilizer requirements for canola production in eastern Canada.
