Wheat yield in Japan is about half that of high-yielding countries in Northwest Europe. Explanations offered so far—such as high temperatures and a rainy summer season shortening wheat's growth period, or comparatively underdeveloped breeding and cultivation techniques—remain speculative. This lack of clarity risks misdirecting research efforts on wheat cultivation in Japan and possibly other parts of the world. To address the issue, the present study focused on the efficiency of yield formation, rather than yield itself, across Japan and Northwest Europe. The efficiency of yield formation, derived from the division of actual yield by sunshine hours during the specific growth period from ear emergence to maturity, was compared between two geographical regions while factoring in climate variables. Despite the large yield difference, there was no significant difference in the efficiency of yield formation of wheat between the two regions. This indicates that Japan's low yield is largely due to climatic adversity for wheat, that is, high temperature, high precipitation and short sunshine hours during the critical growth phase for yield formation of the crop. The implication is that improvements in breeding and cultivation techniques alone are not likely to significantly increase wheat yield in Japan. A fruitful direction for future research endeavors in wheat production in monsoon Asia was discussed.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 6","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70154","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145521448","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}

Based on panel data from 27 provinces in China from 2004 to 2018, this study empirically tested the impact of specialized agricultural services on fertilizer application intensity. Considering potential spatial spillover effects, a spatial lag model was employed. Results showed that specialized agricultural services effectively reduced fertilizer application intensity. Furthermore, there was a positive spatial spillover effect of specialized agricultural services on fertilizer application intensity, likely due to cross-regional specialized agricultural services. Specifically, for every 1% increase in the level of specialized agricultural services, the fertilizer application intensity within a province decreased by 0.040%, while that in neighboring provinces increased by 0.009%, resulting in a negative net impact of specialized agricultural services on fertilizer application intensity. These findings suggested that specialized agricultural services could be promoted in regions with fertilizer overapplication, and service standards and specifications should be established to mitigate the positive spatial spillover effect of specialized agricultural services on fertilizer application intensity.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 6","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70153","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145521387","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}

To elucidate the relationship between transpiration rate and stomatal morphology, this study investigated the effects of four distinct levels of N supply (N0, N0.1, N0.2, and N0.4) on stomatal density (SD) and morphology across both adaxial and abaxial leaf surfaces, alongside their impact on diurnal (Ed) and nocturnal (En) transpiration rates in potato plants. The findings indicate that SD decreases with increasing N supply on both leaf surfaces. Furthermore, stomatal apertures were consistently larger on the abaxial surface compared to the adaxial surface across all N supply treatments. While En remained largely unaffected by variations in N supply, Ed exhibited a non-linear decrease as N supply increased, reaching its minimum value at the N0.2 level. This reduction in Ed, which plateaued at N0.2, is likely associated with the larger stomatal aperture on the abaxial surface at the highest N supply level (N0.4) compared to the other treatments. Overall, the results suggest that N supply primarily reduces Ed by decreasing SD, while also maintaining a larger stomatal aperture on the abaxial surface under high N conditions to optimize the balance between CO2 uptake and water loss. The findings can provide valuable insights into the role of N supply for sustainable crop management, particularly in optimizing water-use efficiency.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 6","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70150","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145407443","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}

This study used survey data from 1492 households and a multinomial logit model to analyze seed systems choice by smallholder sorghum grain producers in Tanzania. Results showed that 84% of the farmers relied on the informal seed system, 11% on an integrated seed system (involving a combination of informal and formal systems), and only 5% exclusively accessed seed through the formal system. Farmers mainly accessed information on seed, agronomy, and markets from their peers. Proximity and participation in input and output markets, financial literacy, use of crop insurance, and access to financial and extension services were associated with a high likelihood of using formal seed systems. On the other hand, limited access to agronomic, and seed information from peers, as well as long distances to main markets, were associated with the use of informal seed systems. The integrated system was associated with intercropping and willingness to experiment with new ideas and technologies. Making sufficient quantities of quality seed available to farmers at the last mile through various channels, improving farmers' access to financial services, and developing multiple stress-tolerant varieties can enhance the use of improved varieties and formal channels of seed access. We recommend innovative ways of moving sufficient quantities of quality seeds of improved varieties through the informal seed system in the interim while further developing the formal system in the long run.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 6","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70148","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145366998","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}

While burgeoning research on adaptation exists, there is a lack of an in-depth account of the specific strategies that farming communities in Bangladesh adopt to become more resilient to climate change impacts. Hence, the present study seeks to answer the following questions: (i) what are the predominant climate change adaptation strategies adopted by Bangladeshi farming communities, and how do these strategies vary across different agroecological zones? and (ii) what are the primary institutional, economic, and environmental barriers to the effective implementation of these adaptation strategies? Employing the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) technique, this study conducted a theory-driven literature review (published between 2000 and 2024) using three prominent journal databases: Scopus, Web of Science, and Google Scholar. The primary strategies being used by farmers to boost agricultural resilience are crop diversification, water management approaches, adoption of new technology, the transition to more resilient varieties, and community-based adaptation. However, the effectiveness of these strategies depends heavily on community efforts at the local level, as well as the type of crop grown, the local climate, and the availability of resources. Our synthesis also reveals that resource-poor farmers need support from the government and other external sources to successfully upscale these intervention strategies to enhance resilience against climate change impacts.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 6","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70147","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145366997","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}

With climate change intensifying drought and expanding disease incidence, it is critical to understand how combined abiotic and biotic stresses influence plant defense. We investigated the transcriptomic response of a susceptible soybean cultivar to ASR infection under normal and water-limited conditions at four infection stages (12, 24, 72, and 192 h after inoculation). We observed a biphasic expression of defense-related genes, particularly resistance gene analogs (RGAs), with an early peak at 12 h and a late resurgence at 192 h. Combined stress induced a greater number of differentially expressed genes (DEGs) than rust alone, especially at early infection. Among the differentially expressed RGAs (RGADEs), over 64% belonged to the TM-LRR class, and NBS-LRR genes were the most enriched at known ASR resistance loci, particularly Rpp2. Water limitation strongly modulated gene expression at late stages, revealing stress-specific transcriptional reprogramming. These findings were consistent with the activation of potential cross-tolerance mechanisms in soybean, highlighted the temporal dynamics of RGADEs under dual stress, and provided potential targets for developing cultivars with improved resilience to both rust and water scarcity.","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 5","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70144","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145366458","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}

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.

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}
