“…One possible explanation is that the split application of mixed N fertilizer (F2) resulted in insufficient N supply during this period. Another reason may be the slow release of nutrients from controlled‐release urea (Mi et al., 2018; Mi et al., 2017). Significantly higher soil NH 4 + and NO 3 − contents were observed under treatment F2 compared with treatments F1, F3, and CU, and the biomass accumulation from booting to anthesis and from anthesis to maturity was higher in treatment F2 than in treatments F1, F3, and CU.…”

“…Additionally, several studies have reported that the use of controlled‐release urea allowed a higher efficiency of N use and yield than under common urea application (Mi et al., 2019; Sun et al., 2019; Zheng et al., 2016). The benefits of controlled‐release urea appear to be strongly affected by environmental factors such as soil moisture and temperature, which contribute to N losses (Grant et al., 2012), and the effectiveness of controlled‐release urea varies with the coating material, cropping system, and cultivation conditions (Lyu et al., 2015; Mi et al., 2017; Ye et al., 2013). Therefore, the potential of the use of controlled‐release urea must be assessed by considering the environmental conditions in different regions.…”

“…Several studies have shown that in China, controlled‐release urea is mostly applied as a single basal application, and the N release from controlled‐release urea is too slow for it to be an effective N source under certain circumstances (Farmaha & Sims, 2013; Guo et al., 2017). For example, a single application of polymer coating of sulfur‐coated urea was not effective in increasing the grain yield of early rice, which was related to the delayed release of N between the tillering and heading stages (Mi et al., 2017). Compared with rice, wheat has a longer growth period (even more than 230 d; Zhao et al., 2020), and therefore, a single application of N fertilizer is more likely to lead to insufficient N supply in the later growth stage of wheat.…”

A 2‐yr field experiment was conducted to investigate the quality, agronomic, and economic performance of controlled‐release urea application in wheat (Triticum aestivum) production via five treatments: F1, a single application of mixed nitrogen (N) fertilizer (composed of 65% N from controlled‐release urea with 35% N from common urea); F2, basal application of mixed N fertilizer and topdressing of mixed N fertilizer at jointing; F3, basal application of mixed N fertilizer and topdressing of common urea at jointing; CU, spilt application of common urea as basal fertilizer and at jointing; N0, no N fertilization. The results showed that treatment F2 produced significantly higher grain yield than treatments F1, F3, and CU. The N recovery efficiency, N agronomic efficiency, and N partial factor productivity of treatment F2 were significantly higher than treatments F1, F3, and CU. The higher grain yield and efficiency of N use of treatment F2 were due to the better canopy structure (longer and more erect top‐three leaves) and the higher biomass production, higher N accumulation, and higher net photosynthetic rate during anthesis to maturity. The treatment F2 resulted in significantly higher protein and wet gluten content, and significantly lower starch content than treatment CU. The net profit under treatment F2 was higher than treatments F1, F3, and CU. In conclusion, the application of a mixture of controlled‐release urea and common urea could be a promising alternative application method for N fertilizer to obtain sustainable increases in grain yield, efficiency of N use, economic profit, and improve wheat quality.

“…It is meaningful to agglomerate those findings into systematic cultivation for fragrant rice production. Fertilization is a critical part of achieving the goals of high grain yield in rice production, as reported by numerous studies [19,20]. Previous studies found that the application of zinc and lanthanum in fragrant rice production could enhance 2-AP production and promote fragrant rice productivity [21,22].…”

Fragrant rice (Oryza sativa L.) is a high-valued rice type and possesses a unique aroma with 2-acetyl-1-pyrroline (2-AP) as the critical component. However, the cultivation measures in fragrant rice production are far from perfect. In this study, a new organic-inorganic compound fertilizer was made with organic matter, urea, superphosphate, potassium chloride, zinc sulfate, and lanthanum chloride. A four-year field experiment was conducted to investigate its effects on fragrant rice growth, yield formation, and 2-acetyl-1-pyrroline biosynthesis. Three treatments, i.e., (CK) no fertilizer was applied, (IF) the urea, superphosphate, and potassium chloride were applied at 234 kg ha−1, 450 kg ha−1 and 108 kg ha−1, and (OICF) this new fertilizer composed of 10% organic matter, 26% urea, 50% superphosphate, 12% potassium chloride, 1.9% zinc sulfate, and 0.1% lanthanum chloride, was applied at 900 kg ha−1, were adopted in the present study. Across four experimental years, the results showed that the grain yield in OICF treatment ranged between 5.86–8.29 t ha−1, and was significantly (p < 0.05) higher than that in IF treatment and CK. The improvement in grain yield due to OICF treatment was explained by increased effective panicle number per m2 and seed-setting rate. The highest or equally highest chlorophyll content and the net photosynthetic rate at 20, 40, 60, and 80 days after transplanting were recorded in OICF treatment among three treatments. OICF treatment also increased the aboveground biomass of fragrant rice compared with IF treatment and CK. Moreover, compared with CK and IF treatment, OICF treatment significantly (p < 0.05) increased grain 2-AP content by 30–38% and 10–21%, respectively. The contents of 2-AP related precursors, including proline and 1-pyrroline, also increased due to OICF treatment. This study provided a new organic-inorganic compound fertilizer and suggested that it could be used to achieve the goals of high yield and high grain 2-AP content in fragrant rice production.

“…[28][29][30][31]. In addition, temperature, moisture and physical and chemical soil properties could affect the nutrient release of SRF in soil [21,32], which contributed to the effectiveness of controlled-release urea, which varies with the coating material, cropping system, and cultivation conditions, leading to differences in the absorption and utilization of nutrients in crops and further affecting the grain yield [33][34][35]. In many studies, the influence of the environmental factors on the application effect of SRF is often ignored, which may result in large differences in yield and NUE in different ecological regions using the same fertilization strategy.…”

Environmental conditions (precipitation, temperature and soil properties) differ greatly in different regions and have dual effects on the wheat growth and nutrient release of slow-release fertilizer (SRF). Conventional fertilization methods such as the multiple-split application of urea and the one-time application of SRF may have difficulty achieving a stable and high wheat yield and nitrogen (N) efficiency in various environments. Therefore, the exploration of a rational application strategy of SRF is needed for improving wheat yield and its stability in different regions. A two-year field experiment was conducted in different regions (eight test sites per year) with five patterns: 100% N (270 kg ha−1) SRF applied pre-sowing (M1); 60% N SRF applied pre-sowing and 40% N urea applied at jointing (M2); 60% N SRF applied pre-sowing and 40% N SRF applied at re-greening (M3); M2 reducing the N rate by 15% (M4); M3 reducing the N rate by 15% (M5). The fourth-split application of urea was taken as the control (CK, 270 kg N ha−1). The results suggested that the average yield in M1 decreased by 3.65% of the CK, and the yield stability was poor. Both M2 and M3 significantly increased N efficiency, grain yield and benefit, but the stability of M3 was higher than that of M2 in different environments. Considering further improvements in wheat yield, N efficiency and profit, our results suggested that the twice-split application of SRF, which also improved the adaptability of wheat in different environments, could be recommended for wheat cultivation.
