“…Most inspection guides for rice use chalkiness and the percentage of chalky kernels for grading. The chalky grain rate of first-grade high-quality rice is lower than 10%, while that of inferior rice is higher than 30% in China [ 26 ]. Chalkiness is a complex polygenic trait, and nitrogen fertilizers had significant effects on the chalky trait of rice grain.…”

In China, green food refers to a wide array of certified agricultural and processed edible commodities that are produced strictly following defined standard protocols and labelled with a specified “Green Food” logo. The demand for green labelled rice is rapidly growing due to its higher quality and adherence to safety standards compared to conventional rice. Therefore, the physicochemical and nutritional quality of green rice needs to be further investigated for consumers’ benefits. Using Daohuaxiang 2, one of the most famous types of green rice, we found that green rice was significantly superior to conventional rice in terms of thousand kernel weight, chalkiness, amylose content, and rheological properties. Green rice contained lower levels of heavy metals than conventional rice due to a dramatic reduction in chemical inputs during its cultivation. The concentrations of Cr, As, Cd, Pb in green rice decreased, respectively, from 98.7 to 180.1 μg/kg, 49.8 to 62.3 μg/kg, 7.8 to 9.1 μg/kg, and 29.0 to 42.8 μg/kg on average. Gas chromatography coupled with mass spectrometry (GC–MS)-based metabolomics, in combination with multivariate analysis, revealed that 15 metabolites differentially accumulated when comparing green and conventional rice. Among these, 12 metabolites showed a high accumulation in green rice, including seven amino acids, two sugars, and three fatty acids. Overall, our results suggest the superior quality of a type of green rice that is popular in China, which may boost green rice consumption and facilitate the further expansion of green rice production in China.

“…Properly managing N application is essential in N transformation and remobilization between vegetative and economic organs in plants over the grain filling process, which is beneficial for obtaining good appearance and seed quality 22 . The CR urea significantly enhanced seed quality and improved the appearance and taste quality, which is beneficial for performance in the agricultural market 42 . This is because applied slow‐release fertilizers with ‘peak cutting for valley filling’ characteristics supplied sufficient N for the plants over the reproductive period, which improved seed quality by increasing the stability of the grain‐filling process 43 .…”

BACKGROUND Global food security faces a number of challenges due to increasing population, climate change, and urbanization, while excessive use of nitrogen fertilizers has become a major challenge for sustainable, intensive agriculture. Assessing the impact of agronomic management practices on seed yield, grain quality, and soil fertility is a critical step in understanding nutrientuse efficiency. RESULT The comprehensive evaluation index had good fitness to that of single attribute (i.e. seed yield, crop quality and soil fertility), indicating that the comprehensive evaluation index was reliable. Applying controlled‐release urea (rice in wheat and oilseed rape field: 150 kg N ha−1, other crops: 120 kg N ha−1) plus common urea (30 kg N ha−1) incorporating straw from the previous season across the growing season for cereal and oilseed crops showed a slight improvement in seed productivity and Nuse efficiency among three cropping systems in the traditional evaluation method. Compared with local farm practice (applying common urea of 150 kg N ha−1), applying these practices in combination based on the outcome of the comprehensive evaluation index method decreased the seed yield by −1.27 ~ 29.8% but improved quality and soil fertility for the paddy‐upland cropping system, respectively. CONCLUSION Properly managing N application by applying partial and fully controlled release of urea with or without straw incorporation for a specific crop system has the potential to provide a better compromise among yield, grain quality, and soil fertility in southern China. © 2020 Society of Chemical Industry

“…Environmental factors such as geographical location, climatic temperature, soil and fertility, and N fertilizers have a significant effect on rice productivity and grain quality ( Siddik et al, 2019 , Wu et al, 2020 ). Furthermore, the current farming system also affects crop production and quality due to over-fertilization of synthetic N, which adversely affects soil quality, the environment, and crop production ( Gu et al, 2015 ).…”

Improving grain filling in the presernt farming systems is crucial where grain filling is a concern due to the extreme use of chemical fertilizers (CF). A field experiment was conducted at the experimental station of Guangxi University, China in 2019 to test the hypothesis that cattle manure (CM) and poultry manure (PM) combined with CF could improve rice grain filling rate, yield, biochemical and qualitative attributes. A total of six treatments, i.e., no fertilizer (T 1 ), 100% CF (T 2 ), 60% CM + 40% CF (T 3 ), 30% CM + 70% CF (T 4 ), 60% PM + 40% CF (T 5 ), and 30% PM + 70% CF (T 6 ) were used in this study. Results showed that the combined treatment T 6 increased starch metabolizing enzymes activity (SMEs), such as ADP-glucose phosphorylase (ADGPase) by 8 and 12%, soluble starch synthase (SSS) by 7 and 10%, granule bound starch synthesis (GBSS) by 7 and 9%, and starch branching enzyme (SBE) by 14 and 21% in the early and late seasons, respectively, compared with T 2 . Similarly, higher rice grain yield, grain filling rate, starch, and amylose content were also recorded in combined treatments. In terms of seasons, higher activity of SMEs , grain starch, and amylose content was noted in the late-season compared to the early season. The increment in these traits was mainly attributed to a lower temperature in the late season during the grain filling period. Furthermore, our results suggested that an increment in starch accumulation and grain filling rate were mainly associated with the enhanced sink capacity by regulating key enzyme activities involved in Suc-to-starch conversion. In-addition, RT-qPCR analysis showed higher expression levels of AGPS2b, SSS1, GBSS1, and GBSE11b genes, which resultantly increased the activities of SMEs during the grain filling period under combined treatments. Linear regression analysis revealed that the activity of ADGPase, SSS, GBSS, and SBE were highly positively correlated with starch and amylose accumulation. Thus, we concluded that a combination of 30% N from PM or CM with 70% N from CF is a promising option in terms of improving rice grain yield and quality. Our study provides a sustainable fertilizer management strategy to enhance rice grain yield and quality at the lowest environmental cost.
