“…As a result, the difference in effects of applying N after anthesis on wheat yield between this study and other studies may be related to the experimental environments. The controlled-release urea improved the yield in several production systems [49], and this is consistent with our results ( Figure 9D, Table 1), as are reports on rice yield [50].…”

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.

“…which results in the loss of urea-15 N. 26,27 Under ood irrigation, the more 15 N loss should be attributed to the lateral migration of 15 N. The surface soil has a lower bulk density and a higher porosity compared to the middle soil, the water supply in a short duration under ood irrigation limits the downward movement of irrigation water and promotes horizontal (Fig. 3c), which will increase the risk of 15 N loss through leakage from deep soils.…”

“…However, it is very difficult to accurately predict the demand for N by plants. Due to the need to increase rice yields, overuse of N fertilizer is common, especially in China (Li, Lu, Wang, Wang, & Hussain, 2018;Miao, Stewart, & Zhang, 2011;Qiao, Yang, Yan, Xue, & Zhao, 2012). However, continuous application of N fertilizer results in environmental pollution and disturbs the ecological balance (Hossain & Siddique, 2015).…”

Integrated crop management practices can improve rice (Oryza sativa L.) grain yield, but the effects of such practices on dry matter accumulation and photosynthetic productivity are inconsistent and not well understood. The primary objective of this study was to investigate the effects of integrated crop management practices on dry matter accumulation and redistribution, photosynthetic production, and yield of rice in northeast China. Medium‐ and high‐yielding potential japonica rice cultivars were grown using four crop management practices, including no N application (N0), local farmers’ cultivation practice (FP), high‐yield cultivation practice (HYP), and super‐high‐yield cultivation practice (SHYP). The increases in average yield with the HYP and SHYP treatments were 16.87 and 36.70%, respectively, in 2017 and 14.70 and 31.05%, respectively, in 2018, compared with FP. Increases in effective panicle number and spikelet number per panicle were the main reason for the increase in yield under the integrated crop management treatments. Compared with FP, the HYP and SHYP treatments significantly increased the population dry matter by 26.40 and 56.64%, respectively, before the heading stage. Relative to N0 and FP, HYP and SHYP significantly increased the dry matter export, export rate, and translocation rate in the leaves, stems, and sheaths and significantly increased the photosynthetic potential throughout the growth stage and the net assimilation rate after the tillering stage. These increases were critical for improving the quality of rice and achieving higher yields. Our study provides a theoretical basis for the development of high‐yield cultivation methods for rice in northeast China.
