To inform evidence-based policymaking, this study evaluates the individual and synergistic impacts of organic and mineral soil amendments as part of an integrated soil fertility management technology on food security and nutrition. We apply the multinomial endogenous switching regression and inverse probability weighted regression adjustment to survey data collected from 768 farm households in Cameroon. Our results indicate that the combined use of organic and mineral soil amendments has the greatest positive association with household dietary diversity, followed by the individual use of organic and mineral soil amendments, respectively. We find that mineral soil amendments drive the consumption of meat, pulses and nuts, and roots and tubers, whereas organic soil amendments are associated with the consumption of most food groups except fruits and meat. The combined use of mineral and organic soil amendments favors the consumption of cereals, milk and dairy products, eggs, fruits, meat, pulses and nuts, and roots and tubers, highlighting the value of integrated soil fertility management. Our findings reaffirm the value of integrated soil fertility management for food security and nutrition and underscore the need for interventions to promote integrated soil fertility management practices in agrarian settings.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70145","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145316853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although combining different cultivation techniques can alleviate the harm of salt stress to crops to some extent, the specific metabolic mechanisms by which crops adapt to salt stress remain incompletely understood. This study focuses on uncovering this crucial mechanism and conducts an in-depth exploration by integrating and analyzing the transcriptomic and metabolomic data of foxtail millet (Setaria italica) subjected to salt stress under different combinations of soil amelioration techniques. These results show that the combined application of organic fertilizers and soil amendments significantly enhances the activities of antioxidant enzymes (superoxide dismutase [SOD] and peroxidase [POD]) and promotes the accumulation of osmotic regulators (soluble proteins and proline) in salt-stressed foxtail millet. Moreover, in the soil with biochar added, the content of the flavonoid compound kaempferol increases significantly, while in the soil with only organic fertilizers or soil amendments applied, the content of kaempferol decreases significantly. This study also reveals that the expression patterns of key genes in the flavonoid synthesis pathway are consistent with the accumulation of corresponding metabolites, and a large number of transcription factors are involved in the salt stress response process. These results suggest that under salt stress, different soil amelioration techniques in combination can strengthen the antioxidant defense system and adjust the flavonoid metabolic pathway to enhance the salt-stress resistance of foxtail millet, providing an effective strategy for enhancing crop productivity on saline soils.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70130","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EU members demonstrate substantial improvements in sustainability, contrasting with mixed progress patterns observed in other major economies; and (3) five clusters are identified: leading performer (USA), resilient performers (like Canada and Germany), innovative performers (China, Japan, and South Korea), moderate performers (like Saudi Arabia and South Africa), and vulnerable performers (India and Indonesia).

Three N rates were imposed: 225 kg ha−1 (N1), 270 kg ha−1 (N2), and 315 kg ha−1 (N3). Across the N1–N3 gradient, supplementary N significantly increased grain yield, total N accumulation (NA), and N translocation. Activities of key N-metabolizing enzymes—nitrate reductase (NR), glutamate synthase (GOGAT), and ferredoxin-dependent GOGAT (Fd-GOGAT)—were also markedly enhanced, indicating improved N assimilation. Throughout grain filling, the high-yielding variety (HYV) maintained superior NR and GOGAT activities relative to the low-yielding variety (LYV). Fd-GOGAT activity in HYV was slightly lower than in LYV at heading (0 DAH) and mid-grain filling (22 DAH), but exceeded LYV levels at maturity (44 DAH). All enzyme activities declined progressively with advancing phenology. Yield was strongly positively correlated with total nitrogen accumulation (NA) (r = 0.958**, p < 0.01), soluble-protein content, GOGAT, and NR activities. Consequently, high NA, elevated soluble-protein concentrations, and sustained GOGAT/NR activities during grain filling constitute robust physiological indicators for identifying high-yielding rice genotypes.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70143","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, to maintain grain yields comparable to medium-grain-weight varieties, adjustments in nitrogen (N) and seeding rate management may be necessary. In this study, the small-grain-weight variety Mabayinzhan was direct-seeded in a three-season field experiment conducted from 2022 to 2023 in Qujiang County, Guangdong Province, South China, using four N rates and three seeding rates. The results showed that grain yield and grain weight ranged from 3.45 to 7.95 t ha−1 and from 11.4 to 14.1 mg, respectively, across all treatments with N application. The variation in grain yield was primarily attributed to differences in spikelets per m2, biomass production, and grain weight. Grain yield generally increased with higher N rates, but no significant difference was observed across the range of seeding rates. The grain yield responded more strongly to N rate than to seeding rate. The decrease in grain yield resulting from lower N rates could not be compensated by increasing seeding rate. While dense planting with reduced N application could improve N use efficiency (NUE), the increase in NUE was due to the reduced N rate rather than the seeding rate. Our findings indicate that high seeding rates are not essential for achieving high yields with a small-grain-weight rice variety. Moreover, increasing planting density while reducing N application may not be optimal for small-grain-weight inbred rice production under direct seeding conditions in South China.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70139","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhanced solar drying technologies are a promising way to reduce losses of perishable foods, thereby enhancing accessibility and potentially increasing dietary diversity. This paper assesses the field-level performance of one chimney dryer design used for drying vegetables, fruits, and fish in rural Bangladesh. A mixed-methods research design was used for this study, including qualitative data analysis based on focus group discussions (FGD) and key informants' interviews (KII), coupled with detailed real-world quantitative assessments of the benefit–cost ratio (BCR), net present value (NPV), and internal rate of return (IRR) associated with the technologies tested. The chimneys were introduced in three locations of southwestern Bangladesh and used by 35 smallholder households. The IRR was found to be relatively high, resulting in profitability within 2 years of operation, depending on the food items selected for moisture removal through the chimney dryers. Two of the three dryers had a BCR > 1, and all three showed positive NPV values. However, none of the chimneys were used at full capacity. These findings suggest that such dryers are both technologically and economically viable, by accelerating drying times, improving food quality and market value, and reducing food losses in the process. The potential exists for enhancing local diets with dried nutrient-rich foods. Promotion of solar chimney dryer technologies could represent an important value-chain investment benefiting adopting households and food purchasers. The economic case would be stronger still if such technologies were used at full capacity for the drying of high-value perishable foods having high demand in local markets.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, improvements in yield under drought are urgently needed. This work evaluated a diverse set of 77 winter-wheat lines for two image-based early vigor traits and 15 mature traits of diverse winter-wheat lines. Early and late drought treatments were applied 12 and 65 days after vernalization, respectively. Further, a machine-learning-assisted phenotyping technique was adopted to measure spike area. Old Swedish cultivars showed the lowest early root vigor (4.92 cm) and large root biomass at maturity (5.25 g). No positive correlation was found between root biomass and yield components under the control condition. A high mean of grain yield was obtained in 1RS (9.8 g/plant), 2RL (9.5 g/plant), and cfAD99 (9.5 g/plant) genotypes under control. When including stability across control and two drought treatments, NGB, 1RS, 2RL, and cfAD99 genotypes showed the best performance. Peduncle length, root biomass, and NDVI positively contributed to the grain yield of 2RL genotypes under early drought, while 1000-grain weight and root biomass accounted for the high grain yield of 1RS genotypes under late drought. The image-based spike area measured by a machine-learning model correlated strongly to the yield component grain number (R2 = 0.70***). Furthermore, combined with yield reduction results, the spike area results suggested increased sterility (empty spikes) as the main cause of drought-induced yield loss instead of changes in spike size. Further integration of traditional measurements, modern phenotyping, and computational image analysis is needed to accelerate evaluations of plant traits under drought conditions. Genes potentially governing drought tolerance can be identified in these diverse lines.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of rice varieties with shorter growth periods has become crucial for effective crop rotation. However, shorter growth periods often result in lower grain yields. Enhancing early growth in these short-duration rice varieties could help offset yield losses, but the genetic potential for early growth remains largely untapped. In this study, we investigated early growth in 90 rice genotypes under field conditions. Significant variation in plant growth was observed at 15, 25, and 35 days after sowing (DAS), with differences becoming more pronounced over time. Seed size had no significant effect on variation in growth rate. Hierarchical clustering analysis grouped the genotypes into five distinct growth patterns: Consistently Slow, Early Surge, Steady Moderate, Delayed Vigor, and Consistently Rapid. These patterns exhibited distinct trends in absolute growth rate (AGR) and relative growth rate (RGR). The Consistently Rapid and Early Surge groups showed higher early growth, whereas Delayed Vigor displayed accelerated growth at later stages. Contrary to traditional assumptions, the RGR during the early growth stage was not constant but varied significantly over time. RGR was primarily correlated with net assimilation rate (NAR) rather than leaf mass ratio (LMR) or specific leaf area (SLA). Size-standardized RGR and its components followed similar trends, indicating consistent growth dynamics across genotypes. These findings highlight distinct early growth patterns among rice genotypes, providing valuable insights for breeding programs aimed at improving early vigor and optimizing yield in short-duration rice varieties.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70133","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as a byproduct, the fibrous roots of O. japonicus (FROJ) are discarded during the production process, resulting in a waste of resources. Existing studies have demonstrated that the FROJ serves as an important resource for functional food and pharmaceutical applications. However, the application effects of FROJ as a feed resource in livestock remain unclear. This study aimed to evaluate the effects of FROJ on in vitro ruminal fermentation, antioxidant capacity, and microbial communities in yaks. The results showed that dietary FROJ significantly increased the total volatile fatty acids (VFAs), the proportion of acetic acid, and propionic acid compared to the hay group. Furthermore, dietary FROJ significantly reduced the yak's rumen malondialdehyde (MDA) content and significantly increased superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity in the rumen fluid. It also significantly increased the relative abundance of Firmicutes, Actinobacteriota, and unclassified_Lachnospiraceae, as well as the Firmicutes to Bacteroidetes ratio in yak rumen. Spearman's correlation analysis of the microbiota, rumen fermentation parameters, and antioxidant capacity revealed positive and negative regulatory mechanisms. In conclusion, dietary FROJ can improve ruminal fermentation and antioxidant capacity in yaks, and this improvement may be associated with an increase in potentially beneficial microbiota. Our findings indicate that the FROJ can be utilized as a feed supplement for ruminants, serving to enhance their immune responses and alleviate the resource wastage.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70132","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
