“…Many studies have shown that increased nitrogen (N) fertilizer application or shifting N before and after will cause a significant increase in the storage protein content of rice [8,9]. Studies have also shown that increased N fertilizer application significantly increases the total protein, albumin, gliadin, and gluten contents of rice grains [10]. In recent years, the practice of high-quality rice cultivation has shown that the amount of N fertilizer application will increase the protein content of rice and decrease rice taste [11,12].…”

Low-gluten rice cultivar D105 was grown in the field under five nitrogen (N) treatments (N0: 0, N90: 90, N135: 135, N180: 180, and N225: 225 kg·hm−2) to investigate the effect of N application rate on the yield and the resulting dynamic changes in protein content, grain processing quality, and relative content of each component protein. The results indicated that the number of effective panicles, seed setting rate, the number of solid grains, dry matter, leaf nitrate reductase and glutamine synthetase activities, and yield increased with N application rate ranging from 0 to 180 kg·hm−2. However, the seed setting rate and the number of solid grains decreased under N225 treatment, leading to a decline in yield. At maturity, 35 days after flowering, no significant differences between albumin and gliadin in the rice grain were found among the N treatments, while globulin and gluten differed among treatments, indicating that the effect of N application rate on the former was slightly the opposite to that observed on the latter. Further, the N application rates did not change the proportions of component proteins relative to the total protein content in the grain. Processing and taste qualities of D105 low-gluten rice were optimal in the N135 and N180 treatments, and the overall rice quality decreased under the N225 treatment. Therefore, the optimal N application rate for yield and processing quality of D105 low-gluten rice is N180: 180 kg·hm−2.

“…The high grain protein content recorded in nitrate-treated plants as opposed to those that received urea was probably due to the timely release of nitrogen (for plants uptake) by nitrate compared to urea which had to mineralize into available N. Plant's timely nitrogen physiological condition (especially at flowering) at higher rates significantly increases its final total seed protein (gliadin, albumin, and gluten) content (Kaizzi et al, 2012;Han et al, 2020;Alhammad et al, 2023b). The results of this study were consistent with those observed by previous scholars (Ochieng' et al, 2021;Ogega et al, 2022).…”

The soil's capability to adjust and mitigate the effects of water shortage due to climate change is limited in some regions such those that suffer from the low rainfall rates. This experimental field study aimed to assess the effects of two inorganic nitrogen forms on maize performance (i.e., growth, yield, grain protein content, and gross returns) and rainwater use efficiency (RUE). Treatments comprised three replicates of synthetic nitrogen forms (i.e., urea and nitrate) that were located in the main plots with four levels that were assigned to the subplots (i.e., 0, 25, 50, and 100 kg N ha-1). Nitrate application resulted in a higher plant height (62 cm) at the vegetative phase with superior values (11.6%) recorded in grain protein than those obtained from other treatments. In addition, the highest grain yield was obtained in nitrate-treated plots in comparison to other N application forms. The leaf area index registered optimal values when 50 kg N ha-1 was applied. On the application of two nitrogen forms, nitrate resulted in a higher RUE (2.1-3.4 kg ha-1 mm-1) than that obtained from maize treated with urea (1.3-1.9 kg ha-1 mm-1). This translated to a 123-234% increase in RUE over the control (N0), which is the key smallholder farmers’ practice. It is recommended that producing maize using nitrate nitrogen at 50 kg N ha-1 as opposed to urea can increase yield stability, and rain use efficiency with higher gross returns in water-scarce agro-ecologies in SSA.

“…Rice bran is composed of 50% carbohydrates (mainly starch), 20% fat, 15% protein, and 15% dietary fiber, mainly insoluble fiber (Sapwarobol et al., 2021). Although albumin and globulin have high levels of essential amino acids such as lysine and threonine, they are almost completely removed during rice processing and are not ingested by consumers (Han et al., 2021; Kaur et al., 2016). Gingerol B and pantothenic acid are important metabolites of purple waxy rice and are closely related to other nutrients: citric acid and isocyanate are the main metabolites in rice processing and have good correlation with various biochemical indexes; pantothenic acid, microglobulin, l ‐glutamic acid, swimming peptide, diosgenin, and Dioscorea protein can be used as metabolite markers to screen the antioxidant activity of waxy rice (Xiong, Zhang, et al., 2022; Zhu et al., 2022).…”

In this study, we analyzed the differences in metabolites between semiwaxy japonica rice (Yangnongxiang 28 [YNX28]) and conventional japonica rice (Hongyang 5 [HY5]) before and after brown rice milling. The metabolites of brown and milled rice grains from the two rice varieties were analyzed by LC–MS‐based nontargeted metabolomics. A total of 266 differentially abundant metabolites (DMs) were tentatively identified in brown rice grains of YNX28 (YNX28B) compared with milled rice grains of YNX28 (YNX28H), and these included 248 upregulated and 12 downregulated DMs. A total of 273 (234 upregulated and 39 downregulated) DMs were tentatively identified in brown rice grains of HY5 (HY5B) compared with milled rice grains of this variety (HY5H). Kyoto Encyclopedia of Genes and Genomes pathway involved and enrichment analyses revealed that 53 and 7 metabolite pathways were enriched and significantly enriched (p < 0.05), respectively, in the DMs identified in YNX28B compared with YNX28H, and the main enriched pathways were related to starch and sucrose metabolism, glycerol phospholipid metabolism, arginine and proline metabolism, and glycine, serine and threonine metabolism. Forty‐six metabolite pathways were enriched in DMs identified in HY5B compared with HY5H, and these included 16 pathways that were significantly enriched (p < 0.05); in addition, the main enriched pathways were related to starch and sucrose metabolism, glycerol phospholipid metabolism, arginine and proline metabolism, and glycine, serine and threonine metabolism. This study provides a theoretical reference for further on the changes in metabolites during rice processing and provides a basis for improving the nutritional quality in rice.Practical ApplicationOriginal data were obtained regarding the changes of different metabolites in semiwaxy japonica rice and conventional japonica rice before and after processing. The purpose of this study was to investigate the difference of metabolite loss in two rice varieties before and after processing. This paper reports on the differences of metabolites between the two types of japonica rice before and after processing, as well as the changes of key metabolites before and after processing, it also provides important theoretical basis for developing new rice varieties with good nutritional quality.
