“…In recent years, there has been an increasing amount of literature on field evaluation of surface fertigation (Playan and Faci, 1997; Garcia‐Navarro et al, 2000; Sabillón and Merkley, 2004; Burguete et al, 2009b; Ebrahimian et al, 2012; Simunek et al, 2016; Zhang et al, 2018). Field data have been used to determine appropriate strategies to improve fertigation management as well as calibration and validation of developed models.…”

One of the important factors in fertilizer application efficiency in surface fertigation is the shape of inflow hydrographs. In this research, a fertigation model is developed to analyse the effect of surge flow on furrow fertigation. Saint-Venant equations and the advection-dispersion equation were used to estimate water flow and solute transport characteristics, respectively. The field experiments, including different fertigation treatments with surge flow, were conducted to calibrate and evaluate the developed model. Most of the water and nitrate losses occurred through runoff; water losses through runoff ranged from 13.8 to 33.4%, while fertilizer losses varied between 5.1 and 47%. Water and nitrate losses in the second fertigation experiments were higher than those in the first due to the reduction of the surge effect. A comparison between simulated and observed data shows appropriate accuracy of the developed model; the root mean squared error (RMSE) index for nitrate and water runoff losses was 8.4 and 12.1%, respectively. Fertigation during all advance surges was recognized as the desirable option in furrow irrigation with a surge flow.

“…but the specific energy under RP was lower than those under the control and WI. Those results implied that adopting the RP could reduce direct energy input, offsetting the decreased system productivity and energy output from grain yield, and that adopting the RP can be expected to achieve identical results with those under well-irrigation planting in dry semi-humid regions due to better soil water conservation 21,40 .…”

The well–irrigated planting strategy (WI) consumes a large amount of energy and exacerbates greenhouse gas emissions, endangering the sustainable agricultural production. This work aims to estimate the economic benefit, energy budget and carbon footprint of a wheat–maize double cropping system under conventional rain–fed flat planting (control), ridge–furrows with plastic film mulching on the ridge (RP), and the WI in dry semi-humid areas of China. Significantly higher wheat and maize grain yields and net returns were achieved under RP than those under the control, while a visible reduction was only found for wheat grain yields when compared with the WI. The ratio of benefit: cost under RP was also higher by 10.5% than that under the control in the first rotation cycle, but did not differ with those under WI. The net energy output and carbon output followed the same trends with net returns, but the RP had the largest energy use efficiency, energy productivity carbon efficiency and carbon sustainability among treatments. Therefore, the ridge-furrow planting with plastic film mulch over the ridge was an effective substitution for well–irrigated planting strategy for achieving sustained agricultural development in dry semi-humid areas.

“…The RFPFM system, as one of the water‐saving practices, is currently popular in arid and semi‐arid areas of northwestern China (Li et al., , , ; Zhang et al., ; Zhou, Li, Jin, & Song, ). The RFPFM system is comprised of alternate flat furrows and mulched hemispherical ridges, which has a greater potential for rainwater collection and therefore leads to deeper water penetration in furrow by preventing evaporation from the soil (Li et al., ; Zhang et al., ; Zhou et al., ). This construction model of RFPFM favors the absorption of light rainfall efficiently while suppressing surface runoff of heavy precipitation (Li et al., ).…”

“…Furthermore, the ridges mulched with plastic film reduce heat exchange between the soil and ambient air, leading to increased topsoil temperature of mulched ridges and thus promoting seedling emergence and crop growth in winter wheat, except for a few studies reporting the negative effect of plastic film mulching in spring wheat (Li, Wang, & Xu, , , ). Additionally, the RFPFM system has several other advantages, such as reduced weeds and pests pressure, more efficient use of soil nutrients and solar radiation, better crop growth, and higher yield performance (Gan et al., ; Li et al., ; Shah & Wu, ; Zhang et al., ).…”

“…Several agronomic management techniques, such as appropriate planting density, proper dosage of N fertilizer application, reasonable irrigation regimes, and plant growth regulators have been used to control the risk of lodging in wheat and other field crops (Ahmad et al., ; Berry et al., ; Kuai et al., ; Wu & Ma, ; Wu et al., ). For instance, excessive N rates promote stem and leaf elongation, resulting in taller plants that are susceptible to lodging (Mirabella et al., ; Tripathi et al., ; Zhang et al., ). Therefore, this study aimed to examine the effects of N application rates and wheat varieties on the incidence of lodging and related morphological parameters, and assess the feasibility of increasing lodging resistance and grain yield simultaneously, through appropriate agronomic practices under RFPFM.…”

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.
