However, yield expression and cultivar selection responses in groundnuts are influenced by genotype-by-environment interactions (GEI) and management conditions. Therefore, it is essential to evaluate GEI to identify high-yielding and stable groundnut genotypes preferred by farmers and markets for breeding or variety recommendations. The objectives of this study were to assess the GEI and farmers' preference traits in groundnut to facilitate the selection of superior genotypes for release and guide breeding with specific or broad adaptation while integrating farmers' and gender perceived traits. The study was conducted across 18 environments representing agroecological zones and potential groundnut production areas in Tanzania. Sixteen genotypes, including two commercial checks, were evaluated in selected locations using a randomized complete block design. Furthermore, on-farm decentralized trials were conducted across 42 locations following the tricot approach. Significant (<i>p</i> &lt; 0.05) variations were detected among the tested genotypes (G), environments (E), and GEI effects on kernel yield. Genotype ICGV-SM 05534 had a relatively highest kernel yield of 927.232 kg ha⁻¹. The GGE biplot identified ICGV-SM 16645 and ICGV-SM 10014 as the most stable genotypes across locations, with mean kernel yields of 936.39 and 877.67 kg ha⁻¹, respectively. The triadic comparison of technologies (TRICOT) analysis identified gender differences in trait preferences among groundnut growers. Early maturity, ease of harvesting and shelling were the most preferred traits by female farmers, and haulm yield by males. Tan color and small-medium kernel seed size were identified as the top traits selected by farmers' overall varietal preferences. Additionally, early maturity is an important trait to consider in the market segment. Farmers' preference traits are crucial during the initial stage of designing the target product profile to increase the adoption of the deployed groundnut variety. The selected genotypes, test environments, and farmer-preferred traits are vital for breeding pipelines, targeted variety release, and production for different target population environments (TPEs) in Tanzania.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 2","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70228","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668449","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, the systemic differences in physiological and transcriptional regulatory mechanisms between C₃ and C₄ crops under long-term fluctuating light remain poorly understood. Herein, maize variety “Yunrui 408” and rice variety “Dianheyou 615,” both widely cultivated in Southwest China, were used to investigate responses to long-term fluctuating light (FL) versus steady light (SL) via integrated analyses of phenotypic traits, photosynthetic physiology, transcriptomics, and protein–protein interaction (PPI) networks. Results showed that long-term FL causes greater yield losses (&gt; 30%) in rice, including reduced 100-grain weight and shoot dry weight, whereas maize exhibited milder yield suppression (&lt; 20%) and enhanced starch/sucrose accumulation in grains and leaves. Maize maintained stable photosystem function via a synergistic mechanism. A large plastoquinone (PQ) pool buffered electron transport fluctuations, while the transcription factor ZmMYB93 coordinated the upregulation of carbon storage (<i>ZmAGPS1</i>), energy supply (<i>ZmGAPC3</i>), and carbon assimilation (<i>ZmFBA3</i>) pathways to sustain metabolic homeostasis. In contrast, rice showed decreased photosynthesis under long-term FL, characterized by downregulated core photosynthetic genes (<i>OsPsaA</i>, <i>OsPsbA</i>) and ATP synthase genes (<i>OsAtpB</i>). This suppression was driven by the PEL-GLK inhibitory module; subcellular localization assays confirmed that OsPEL1 is a nuclear-resident protein that physically interacts with GLK transcription factors within the nucleus to repress the transcriptional activation of core photosynthetic genes. Rice also relied on passive cyclic electron flow (CEF) and exhibited increased dark respiration, forming a negative feedback loop that impaired carbon assimilation. Overall, C₄ crop maize exhibits stronger adaptability to long-term FL than C₃ crop rice. It adopts an active adaptation strategy by integrating PQ pool-mediated electron transport buffering and ZmMYB93-coordinated nuclear transcriptional regulation. In contrast, rice adopts a passive and inefficient regulatory strategy, where <i>OsPEL1</i>-mediated nuclear inhibition of GLK and enhanced dark respiration lead to photosynthetic apparatus damage and carbon assimilation suppression, ultimately resulting in severe yield loss. These findings provide a blueprint for improving C₃ crop light-use efficiency by leveraging the active regulatory mechanisms identified in maize to mitigate yield losses in dynamic field environments.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 2","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70230","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668161","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 employed the Quantile Regression (QR) model to investigate the determinants of wheat and maize production across different productivity levels in Egypt and to analyze the impact of recent fertilizer market disruptions on farm productivity and profitability. Our empirical results indicate a 20.9% decline in total nitrogen fertilizer use per hectare in Egypt between 2018 and 2024, driven by a reduction in non-subsidized fertilizer use, highlighting a reliance on government support due to market volatility and high input costs resulting from geopolitical instability and global fertilizer market fluctuations. Furthermore, the results confirm that key production factors, such as nitrogen fertilizer use, land expansion, and institution structure, affect yields differently across production quantiles (farms), underscoring the limitations of a one-size-fits-all policy approach. Therefore, our findings advocate for context-specific policies, including tiered subsidies, differentiated extension services, and technology adoption strategies tailored to the specific context. Future policies should focus on empowering cooperatives to facilitate access to new technologies and training for farmers, as they are more likely to engage with cooperatives than with other organizations. In addition, supplementary investments in soil fertility, water management, and improved agricultural practices to reduce nitrogen fertilizer application and achieve economic and environmental benefits are crucial for long-term farm viability and food security. Furthermore, price transmission shifted from energy to agricultural inputs and then to food product prices, making government agricultural input subsidies essential for affordable food and food self-sufficiency. Finally, securing subsidized fertilizer is necessary to mitigate future shocks.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 2","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70224","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579910","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}

{"title":"Inflation Surges, Dietary Diversity and Healthy Diets, and Coping Strategies: Evidence From Rural Türkiye","authors":"Neville N. Suh,&nbsp;F. Abay Canan","doi":"10.1002/fes3.70227","DOIUrl":"10.1002/fes3.70227","url":null,"abstract":"<p>The recent 2021/22 global surges in inflation have remained heightened in most parts of the world, resulting in additional millions of people experiencing food insecurity and malnutrition, with disproportionate effects on the world's most vulnerable people, particularly poor rural farmers. Moreover, food prices are more likely to continue to surge in the foreseeable future. This is especially true in Türkiye, where food price inflation continues to record peak values with persistent increases and widening divergence from global food price inflation. Understanding how inflation surges (food price and nonfood expenditure shocks) affect dietary diversity and the different coping strategies poor rural farm households use remains a crucial gap in the global literature. Using household-reported inflation shocks during the height of the 2021/22 inflation surge, we test whether escalating inflation surges are severely undermining farm households' intake of diverse diets and healthy foods, and how they respond to these shocks in rural Türkiye. We show that households are especially vulnerable to the inflation shocks, which negatively affect higher intake of more diverse and healthy diets, though the effect is less pronounced for households with access to government premium input support. Meanwhile, we find that households that experienced an inflation surge implemented coping strategies, which are important for smoothing their consumption of diverse foods and healthy diets. However, some of the strategies implemented are associated with less diverse food varieties and greater intake of unhealthy diets, indicating that households use both beneficial and harmful strategies. Robustness checks show that inflation shocks significantly reduced the likelihood of consuming nutrient-dense foods. The evidence underscores the significance of more diverse foods and healthy diets within the nutrition and economic development framework and provides vital information on the extent to which non-erosive adjustment strategies can help rural poor farmers cope with inflation shocks. Furthermore, interventions aimed at stabilizing inflation surges are crucial for mitigating the adverse effects of shocks on the nutrition of poor rural farm households.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 2","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70227","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579711","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}
