“…In the present study, the highest grain yield and NUE were also achieved under 7.5 × 10 4 plants per ha with SF. The application of slow released fertilizer has been proven to increase the grain yield and NUE of maize compared with conventional urea by numerous studies (Diez et al, 1994;Hu et al, 2013;Zhao et al, 2013;Zheng et al, 2016Zheng et al, , 2017. Increased plant population density could increase grain number and decrease grain weight in maize production (Li et al, 2018;Poneleit & Egli, 1979;Rossini, Maddonni, & Otegui, 2011), and N starvation exerted negative effects on final kernel numbers and weight (Boomsma, Santini, Tollenaar, & Vyn, 2009;Hokmalipour et al, 2010;Li et al, 2018).…”

“…Furthermore, increasing the frequency of top‐dressing applications is usually unacceptable due to practical and economic reasons. The application of controlled release fertilizer could release N gradually to coincide with the N demand of the crop (Grant et al., 2012; Ye et al., 2013) and has been proven to increase the grain yield and NUE of maize compared with conventional urea by several studies (Diez et al., 1994; Hu et al., 2013; Zhao, Dong, Zhang, & Liu, 2013; Zheng et al., 2017). Previous research on fertilization and planting densities focused on common fertilizer, however, there have been few attempts to evaluate the effects of slow‐released fertilizer on post‐silking N uptake and translocation, SLN, NUE, and grain yield in comparison with conventional fertilizer under different plant densities.…”

Rational plant density and fertilizer management are important practices to improve maize (Zea mays L.) yield and nutrient use efficiency. Previous research indicated that plant density and fertilization had positive interaction on maize yield and N utilization. The research studied on the interactive effects of slow‐released fertilizer (added amino acid polymer biological preparation) and density on maize yield and nitrogen use efficiencies (NUEs). A 2‐yr field experiment with varieties Suyu29 (SY29) or Suyu30 (SY30) was conducted using a split‐split plot design. Three densities (6.0, 7.5, and 9.0 × 104 plants per ha) and three fertilization modes (0F‐no fertilizer, SF‐one‐time application of slow‐released fertilizer, and CF‐twice application of conventional fertilizer) were assigned. Results indicated that grain yields and NUEs of SF under 7.5 × 104 plants per ha were the highest both in SY29 and SY30. Compared with CF under 7.5 × 104 plants per ha, SF could improve pre‐ and post‐silking N uptake and promote N translocation from stalk and leaf into grain, which increased its contribution efficiency to grain N content and obtained higher NUE. The average N partial productivity, N agronomic efficiency, N recovery efficiency, and N absorption efficiency of SF were 5.3, 9.9, 20.1, and 11.4% higher than CF under 7.5 plants × 104 plants per ha. Increasing plant density, the grain yield, total N accumulation, and NUEs initially increased and then decreased both in SF and CF. These results suggest that one‐time application of SF combined with appropriate density could increase maize yield and NUE under our experiment condition.

“…The agro‐climatic conditions of a site directly affect biomass production, yield (Krupnik et al., 2015) and N uptake (Agyin‐Birikorang et al., 2017). To know about of interaction between the agro‐ecosystem and the N supply (Nendel, Melzer, & Thorburn, 2019), is extremely relevant in terms of the N accumulation (Dourado‐Neto et al., 2010) and grain yield in wheat crops (Elía, Slafer, & Savin, 2018; Zheng et al., 2017). Rainfall conditions and soil water stored prior to sowing allows for an increase in both the production of wheat and the N use efficiency of wheat (Moeller, Asseng, Berger, & Milroy, 2009).…”

The use of coated fertilizers and the concept of the critical N dilution curve are alternatives capable of improving the production efficiency of wheat (Triticum aestivum L.) crops in agro-ecosystems. The objectives of this work were to evaluate the effect of a slow release urea-coated fertilizer on (i) the production of wheat's shoot biomass at the anthesis stage, (ii) the concentration of N in the shoot biomass, and (iii) the N availability in the Andisol. Two fertilizers: urea and urea-coated were evaluated using four increasing N rates and a control treatment (without fertilization), in three application strategies, during two growing seasons (late sowing [S1] and early sowing [S2]). Samples of shoot biomass and soil (0-20-cm depths) were collected at five wheat growth stages (Z21, Z31, Z39, Z45, Z69 on the Zadoks scale). The average production of shoot biomass was 10.3 t dry matter (DM) ha -1 for S2 and 7.9 t DM ha -1 for S1 and N concentrations was between 1.0-3.0%. When using a coated urea fertilizer in this Valdivian agro-ecosystem, no statistical differences (P < .05) in shoot biomass or wheat N concentrations were found at anthesis (Z69). Differences were principally between seasons. We therefore proposed a new adjustment to the dilution N curve, with a value concentration critical, N c start of 3.80%, and 4.15%, for S1 and S2, respectively. Use demand parameters such as N c adjusted to the agro-ecosystem for wheat crop, allows to rationalize the fertilization according to inorganic N available from the soil.Abbreviations: AS, all of the fertilizer was applied at sowing; AT, all of the fertilizer was applied at the end of tillering; CU, Nutrisphere-Urea; DM, dry matter; GDD, growing degree days; N c , critical nitrogen concentration; NNI, nitrogen nutrition index; S1, season 1; S2, season 2; SA, split application with one-third applied at sowing and two-thirds at the end of tillering; U, urea.

“…Grain yields with irrigation plus NH 4 NO 3 application and irrigation plus NH 4 HCO 3 application were 148.0 and 163.6% higher, respectively, than that of a no-irrigation, no-fertilizer treatment [9]. A study showed an increase in crop yields, NUE, and profits with the use of mixtures of coated controlled-release and uncoated urea in a wheat-maize system [10].…”

The reported effects of nitrogen (N) fertilizer on wheat yield and nitrogen use efficiency (NUE) vary greatly, due to differences in climate, soil factors, and N management practices in different regions of China. We collected literature published during 1950-2017 that reported the yield and NUE for wheat in China, under N application and control treatments, and analyzed the data therein. A significant increase in yield was observed with N application, and varied with climate, soil factors, and N management practices in different regions. A larger increase in yield was observed under an average annual temperature of 13-15 • C, an average annual precipitation of >800 mm, respectively. Greater yield-increasing effects were observed in soil with a coarse soil texture, lower soil total N, available N, and a soil pH of ≤7 and >8, respectively. In Northwest China, the yield increase was greater under multiple coated urea applications after anthesis, while the higher NUE was observed under single coated urea application before anthesis. In North China, the yield and NUE were greater under multiple coated urea applications before anthesis. In South China, the yield and NUE were greater under multiple N applications. Consequently, to improve wheat yield and NUE, site-specific N management practices should be adopted.
