“…In the maize season, the microplots were moved to the northwestern side of the plots. 15 N-labeled urea, with an abundance of 10.21%, was adopted in both the wheat and maize season (provided by the Shanghai Research Institute of Chemical Industry) and applied at the same dosage as in the corresponding main plot. a The treatments (N1, N2, N3, N4) were described by Liang et al [6].…”

“…The distribution of residual 15 N in the upper 0-60 cm of soil was analyzed and presented in Figure 2. After the wheat harvest, in the 2016 and 2017 growing seasons, the total residual 15 N in the upper 0-60 cm accounted for 22.8-26.8% and 18.8-20.3% of 15 N, respectively.…”

“…are becoming ever more serious [11][12][13]. This phenomenon is particularly of concern in intensive cropping systems [2,14,15]. Therefore, it is essential to resolve the contradictions between optimizing N fertilization management to improve NRE, crop yield, economic returns, and the environment.…”

“…Great progress has been made in optimizing management for NUE [18]. To optimize N management, nitrification inhibitors, fertilizer deep placement, and controlled-release urea are utilized [15,19,20]. Ju et al [17] and Zhao et al [21] have already reported that adopting optimum N fertilization techniques and controlling the primary N loss pathways can decrease the negative effect of excessive N fertilizer on crop quality, NUE, and environmental risk in rice/wheat cultivation.…”

Lower nitrogen recovery efficiency (NRE) and negative environmental impacts caused by excessive nitrogen (N) fertilization threaten the sustainability of agriculture. Efficient and appropriate fertilization practices are extremely important to achieve higher crop yield with minimum N loss. A field microplot experiment was conducted in a wheat-maize rotation system in Shaanxi province, at North China Plain, using the 15N isotope tracer technique to qualify the different annual N managements in terms of crop yield, NRE, N distribution in plant-soil, and N losses to optimize the N management. The experiment included four N treatments: conventional practice with 510 kg ha−1 annually in four applications (N1), and three optimized N treatments, reducing N rate to 420 kg ha−1, adjusting topdressing fertilizer times and using slow-release fertilizer (SRF) (N2, N3, N4). The results showed that the grain yield and N uptake did not differ significantly among treatments. N from fertilizer taken up (Ndff) by wheat was not affected by N management; however, in maize, Ndff performed differently. Optimized treatments significantly decreased the Ndff as compared to N1 treatment. Furthermore, NRE of wheat and annual nitrogen recovery efficiency (annual NRE) did not differ among treatments in 2016 but significantly increased in 2017 compared to N1. Annual NRE in 2017 was similar to that obtained for wheat. For maize, optimized N managements decreased the NRE in N3 and N4 treatments of two years. Potential losses in wheat were also similar amongst treatments, but in maize, N3 and N4 had lower residual N in the soil’s top 60 cm but resulted in higher potential losses than N1 and N2. Overall, our results demonstrate that applying 420 kg N ha−1 annually in three applications and combining SRF and urea are effective to sustain crop yield, improve the efficiency of N usage by maize, and reduce N losses in this region.

“…Studies have shown that different maize cultivars planted at high densities (>79,000 plants ha −1 ) all achieved their highest yields at the maximum N rate applied in the study (Chen, Kumudini, Tollenaar, & Vyn, 2015; Ciampitti & Vyn, 2011; Ma et al., 2015). However, excessive application of N fertilizer can cause environmental degradation and declining agricultural earnings (Chen et al., 2014; Jaynes, Colvin, Karlen, Cambardella, & Meek, 2001; Jin et al., 2012; Snyder, Bruulsema, & Jensen, 2007; Yang et al., 2017).…”

Meeting maize (Zea mays L.) production targets of high grain yields and nitrogen use efficiency (NUE) requires the development of stress-tolerant cultivars and corresponding cultivation practices that maximize efficiency. Therefore, our objectives were to (i) determine the impacts of N application rate, planting density, and maize cultivar (which have improved with each successive release date) on the N partial productivity factor (PFP N ) and N agronomic efficiency (AE N ), and to (ii) characterize the responses of maize cultivars indexes to different cultivation conditions. We found that maize PFP N and AE N values were affected by N application, planting density, and cultivar. The PFP N and AE N declined with increasing N but increased with increasing planting density or genetic improvement (i.e. later year of release). The responses of PFP N and AE N to planting density and N application, taken either as single factors or as interacting factors, were greater for recently released cultivars than for older cultivars. The PFP N and AE N values were not automatically associated with maize yields, indicating that the genetic improvements that led to increases in PFP N and AE N were due to unconscious selection. Thus, improvements in NUE resulted from improvements in cultivars' tolerance to planting density stresses and from cultivation practices that employed higher planting densities from the 1950s to 2010.Abbreviations: AE N , agronomic efficiency of nitrogen; NUE, nitrogen use efficiency; PFP N , partial factor productivity of nitrogen.

Preplant nitrogen (N) application, which involves placing nutrients in the soil before seeding, has been an integral part of crop production systems for decades. Some producers are known to apply N at least 21 d before planting. This may increase N loss and lower grain yield. This study evaluated the effect of timing and rate of N application on winter wheat (Triticum aestivum L.) grain yield and N use efficiency (NUE). An experiment with a factorial arrangement of treatments was set up in a randomized complete block design with three replications. Treatments included four N rates (0, 45, 90, and 135 kg ha–1) with each applied 7 or 30 d before planting, and at Feekes 5 (FK5). Grain N was analyzed using LECO CN dry combustion analyzer. The difference method [Grain N from (fertilized plot – check plot)]/N applied was used to compute NUE. Nitrogen application rate significantly affected grain yield (P ≤ .01). Although the rate may be temporally and spatially variable, approximately 90 kg N ha–1 was required to obtain yields that differ markedly from the check. Mid‐season applied N (FK5) had similar yields to preplant applied N in two of four site‐years and significantly increased yield at one site in 2020. Out of two sites, the timing of N application had a substantial effect on NUE in both years (P ≤ 0.11). In this case, NUE was increased by as much as 9.5% for midseason applied N compared to 30 d before planting N application time.
