“…At the experimental site, low temperature limited nutrient translocation in the late growth stage for foxtail millet. R planting can accelerate the duration of plant growth due to the heat-retaining effect of plastic mulching 1, 9 . Compared with R, it was more difficult for foxtail millet to reach complete physiological maturity under T planting, thereby leading to relatively higher nutrient residues in the straw at harvest.…”

The ridge and furrow rainwater harvesting (RFRH) system is a promising water-saving planting technique for dryland farming, but we lack a full understanding of the effects of different fertilizer rates (N:P) on plant nutrient uptake and nutrient use efficiency (NuUE) in foxtail millet using this planting method, as well as the available nutrient residues in the soil. We conducted field studies (Loess Plateau, China) comparing RFRH planting (R) and traditional flat planting (T) at four different fertilizer rates to determine suitable fertilizer application rates for R during 2013–2015. Compared with T, R improved the soil moisture and the utilization of rainwater and fertilizer, thereby enhancing the grain yield, water use efficiency (WUE), grain nutrient uptake, and NUE in a dry year, but with no improvements in a rainy year. The grain yield and WUE exhibited parabolic increasing trends as the fertilizer application rate increased over three years, but no significant increase was found when the fertilizer rate exceeded 189:96 kg N:P ha−1 under R, which significantly reduced the NuUE and might waste nutrients. Therefore, we recommend R combined with 189:96 kg N:P ha−1 as a promising planting strategy for foxtail millet in semiarid areas.

“…Lu et al (2014) reported that straw mulching decreased yield and nitrogen (N) use in northeastern China. However, studies have demonstrated that plastic film mulching (FM) technology is one of the most effective measures due to the advantages of improving the topsoil temperature, especially in the early spring (Mo et al, 2018; Zhao et al, 2012), raising rainfall utilization and soil moisture content, decreasing the soil evaporation (Li et al, 2016; Wang et al, 2018), and generally improving yield and quality (Chen et al, 2015a, 2015b; Luis et al, 2011) in the arid and semiarid Loess Plateau since the 1970s (Dong et al, 2009; Li et al, 2000).…”

Response of Maize Productivity and Resource Use Efficiency to Combined Application of Controlled‐Release Urea and Normal Urea under Plastic Film Mulching in Semiarid Farmland

Controlled‐release urea is considered to enhance crop yields while reducing labor costs from fertilizer dressing, but the impacts can range widely depending on water availability in soil. Therefore, we conducted a 3‐yr field study to evaluate the potential role of controlled‐release urea in improving productivity and resource use efficiency of maize in semiarid areas in China. Treatments were established as two mulching modes (plastic film mulching [FM] and no mulching [NM]) and three nitrogen application modes (no nitrogen fertilizer [CK], a 1:2 ratio of controlled‐release urea to common urea [CRU], and common urea only [U]). Higher temperature and soil water content under FM treatments significantly accelerated maize growth and development, as indicated in terms of a larger leaf area index before silking, greater biomass accumulation, and greater grain yield. More robust plants with controlled‐release urea under mulching can better absorb and utilize deep soil water to increase water use efficiency (WUE). Mean shoot biomass, grain yield, and WUE during the three experimental years were 35.3, 19.0, and 12.4% higher in mulching with CRU treatments than in NM with controlled‐release urea treatments, respectively. Significant interactions existed for yield and WUE among surface mulching (SM), nitrogen fertilizer (NF), and sampling year (Y) in the three experimental years, except for SM × NF for WUE. These results demonstrate that a mixture of controlled‐release urea and U at an appropriate ratio under SM can provide a better water/temperature/nitrogen conditions for maize growth to realize relatively high yield with labor and time savings in semiarid farmland. Core Ideas Film mulching benefits topsoil temperature, soil moisture, and utilization of deeper soil water. Combining controlled‐release urea (CRU) and urea increased yield and resource use. Combing CRU and urea under plastic film increased yield and WUE. One‐time application of CRU + urea at an appropriate ratio will satisfy spring maize in dryland farming systems.

“…As water is one of the most important reserves for the sustainable development of agriculture, maximizing crop production per unit of water utilization has become a vital strategy to ensure future food security in dry semi‐humid regions (Shah & Wu, ; Wu & Ma, ). Increasing water‐use efficiency (WUE) through water‐saving technologies with efficient use of precipitation instead of relying on irrigation has gained extensive attention worldwide (Gan et al., ; Li 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., ).…”

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.
