“…Grain yield and AE under optimal N management The knowledge-based N management practices can increase rice yield, 31,3,15 which is in line with the present study (Table 1). However, Moe et al 32 and Pan et al 21 thought that optimal nutrient management achieved a similar grain yield compared with FFP. This indicated that rice yield was closely related to various nutrient management measures, such as N application rate, fertilization time and the substitution rate of organic fertilizer.…”

“…Most studies have shown that organic substitution can improve soil structure, regulate soil ecosystem processes and biological interactions, increase soil organic matter content, and improve soil fertility, thus promoting sustainable crop production 16‐20 . A recent study also showed that organic fertilizer substitution improved assimilate storage by increasing the photosynthetic capacity of leaves and stems (source) after flowering, which is conducive to their transport to grain (sink) and increase grain weight, and more conducive to its source–sink balance 21 . The application of organific fertilizer also could synergistically improve NUE and grain quality, including the structure and physicochemical properties of starch, contents of high value protein and amino acids, contents of microelements, and cooking and eating quality 15 .…”

BACKGROUND: Reasonable nitrogen (N) supply is critical for increasing rice yield while improving grain quality and nitrogen use efficiency (NUE). However, the trade-off relationship between yield, quality and NUE of rice under N management has not been well understood enough. In the present study, a 2-year field experiment was conducted to identify optimal N fertilizer management practices that resulted in high-yield, high-quality and high-NUE by using the technique for order preference by similarity to an ideal solution (TOPSIS) with entropy weight (EW) method.RESULTS: All the parameters of rice yield, quality and efficiency were remarkably affected by fertilization treatments. Compared with farmer's fertilization practice (FFP), optimizing N fertilizer treatment (OPT) and substituting 20% of N fertilizer with pig manure based on OPT treatment (OPTM) increased grain yield (2.87-6.62%) by maintaining higher 1000-grain weight and filled grains rate. The agronomic NUE (AE) and N partial factor productivity (PFP) under OPT and OPTM treatment were also remarkably increased by 32.81-43.01% and 28.59-33.28% with respect to the value under FFP treatment, respectively. Meanwhile, OPT and OPTM significantly improved the milling quality of rice by increasing brown rice rate (0.71-1.17%) and head rice rate (1.34-2.31%). OPT and OPTM significantly improved appearance quality by decreasing chalkiness and eating quality by reducing amylose content in 2020. The TOPSIS with EW showed that rice comprehensive evaluation could be maintained at a high level under OPT and OPTM.CONCLUSION: OPT and OPTM were nutrient management modes of high-yield, high-quality and high-efficiency, and promising practice to improve rice comprehensive productivity. This strategy is also highly-consistent with the United Nations Sustainable Development Goals.

“…Second, biological fertilizer and organic fertilizer combined application. The results showed that partial substitution of organic fertilizer for chemical fertilizer had a positive effect on grain yield of summer maize [ 31 ] and can reduce the need for synthetic nitrogen fertilizers while maintaining or increasing rice yields [ 32 , 33 ]. In vegetable production, biofertilizers are not a complete substitute for chemical fertilizers, but the simultaneous use of chemical, organic and biological fertilizers is more effective for potato growth [ 34 ].…”
