Little attention has been paid to smallholder farmers' perceptions, adoption levels with barriers, and influencing factors. This study examines how adoption is determined and the livelihood contribution of AF practices among smallholder farmers in Didu District, Southwestern Ethiopia. This study employed a mixed-method cross-sectional design. Using a multi-stage sampling procedure, 296 respondents (174 adopters and 122 non-adopters) were selected. The collected data were analyzed using thematic, descriptive, and inferential methods. Farmers adopted various AF practices in different home gardens (36 %), scattered trees in croplands (29.71 %), boundary tree planting (16 %), and hedgerows (2.29 %). The major barriers to AF adoption were the lack of extension services (98.3 %), limited land (97 %), and inaccessible markets (94 %). A binary logistic regression analysis was adopted, and it was positively influenced by wealth level (<em>p &lt; 0.01</em>), level of education, size of the farm, slope of the farmland, extension relations, and farming experiences (<em>p &lt; 0.05</em>) and negatively by distance from home to farmland (<em>p &lt; 0.05</em>). Analysis of the net profit margin also showed that practice adopters had higher profitability rates than non-adopters (16.54 % vs. 9 %), and the AF reported economic benefits to smallholder farmers in the study area. The results showed that the diversified nature of smallholder farmers’ livelihoods in the area was largely supported by AF practices. Through AF practices, society has experienced diminished poverty levels together with enhanced food accessibility, and farmers have achieved better earnings and living conditions. This study proposes strategies to enhance AF as a base for enduring socioeconomic progress and supervision of natural resources.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"22 ","pages":"Article 102052"},"PeriodicalIF":4.8,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144168597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the current study was carried out to determine the effects of HAP and Si NPs on mitigating Pb and salinity stress in coneflower (<em>Echinacea angustifolia</em>) through physiological and biochemical attributes. The plants were sprayed with HAP and Si NPs at 200 mg L<sup>−1</sup> and exposed to Pb (600 mg kg<sup>−1</sup> of soil) and salinity (100 mM NaCl).

However, these are prone to deterioration during storage and processing due to microbial and chemical activities, resulting in rancid odors, unpleasant flavors, and texture changes. Proper additives can mitigate these issues, with natural preservatives being preferred over synthetic ones due to safety concerns. Among natural options, polyphenols derived from plants, beverages, and seaweed exhibit strong antioxidant and antimicrobial properties, making them effective and safer alternatives to synthetic preservatives like sulfating agents. Extracts and essential oils from sources such as tea, rosemary, grape seed, ginger, and clove have demonstrated their efficacy in preserving aquatic food quality. Polyphenols present in these plants donate an electron or a hydrogen atom to neutralize the free radicals. These also deactivate reactive oxygen species or suppress the formation of free radicals. Acting as radical scavengers or chain breakers, these stop the oxidation chain reactions. In addition, polyphenols also form metal chelates. The presence of a hydroxyl group in polyphenols is associated with the anti-microbial activities against foodborne pathogens. This interacts with the cell membrane of bacteria and causes its disruption, which results in the loss of cellular content. This review highlights the potential of polyphenols as natural additives to enhance the safety, extend the shelf life, and improve the nutritional profile of aquatic food products.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"22 ","pages":"Article 102046"},"PeriodicalIF":4.8,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the factors influencing maize production potential, cumulative temperature has emerged as a critical determinant. This two-year study assessed four maize varieties with differing cumulative temperature requirements: high cumulative temperature requirement maize varieties (H<sub>CTR</sub>, 2800–2990 °C; Zhengdan 958 and Xuntian 969) and low cumulative temperature requirement maize varieties (L<sub>CTR</sub>, 2200–2450 °C; Jifeng 2 and Junyi 86) under late sowing (end of June). Yield, biomass, leaf area index, photosynthetic characteristics, and crop growth rates were analyzed. Results showed H<sub>CTR</sub> varieties achieved significantly higher yields (19.8 %–25.7 %) than L<sub>CTR</sub> varieties, even with suboptimal cumulative temperatures (2508.8 °C in 2022; 2694.2 °C in 2023). H<sub>CTR</sub> varieties had superior hundred-grain weight (10.7 %) and grain number per cob (12.5 %).

The key mechanism by which H<sub>CTR</sub> varieties maintain high yields under insufficient cumulative temperature could be as attributed to the advanced peak photosynthetic rate and optimized biomass allocation. To draw a conclusion, H<sub>CTR</sub> maize varieties are particularly well-suited for late showing in the rainfed dryland areas of the NCP.

However, research integrating these two approaches remains unexplored. This study aims to evaluate the method of side-deep banding application of liquid fertilizer (D-LF), compare it to side-deep banding application of solid fertilizer (D-SF) and broadcasting of solid fertilizer (B-SF), all synchronized with mechanical transplanting, and explore the impacts of these methods on rice production. Field experiments using the completely random block design were conducted on four indica rice varieties at two locations in South China (Zhaoqing and Jiangmen) during the two rice seasons. Each experiment included a non-nitrogen fertilizer treatment, namely the control (C), and three nitrogen fertilizer application treatments: D-LF, D-SF, and B-SF. The results indicated that at the midterm tillering stage (MT), the D-LF treatment exhibited the best root characteristics, and the tillering number under D-LF increased by 10.36 %–26.54 %, compared to D-SF and B-SF. At the maturity stage (MS), D-LF resulted in a 7.37 %–24.02 % increase in grain yield, compared to D-SF and B-SF. Significant positive correlations were shown between root characteristics and grain yield by Pearson correlation analysis. Additionally, nitrogen use efficiency (NUE) under D-LF was significantly improved relative to D-SF and B-SF. Notably, compared to existing fertilizer application methods, D-LF enhances rice root traits at the early growth stages, improving early tillering capacity and increasing the number of effective panicles, which ultimately boosts grain yield. Moreover, this method effectively improves the NUE and economic profitability. This study is the first to combine the mechanical side-deep fertilization with liquid fertilizer and compare their impact on rice production with traditional methods, offering valuable insights for optimizing nitrogen fertilizer application strategies in rice cultivation.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"22 ","pages":"Article 102042"},"PeriodicalIF":4.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
