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_CTR, 2800–2990 °C; Zhengdan 958 and Xuntian 969) and low cumulative temperature requirement maize varieties (L_CTR, 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_CTR varieties achieved significantly higher yields (19.8 %–25.7 %) than L_CTR varieties, even with suboptimal cumulative temperatures (2508.8 °C in 2022; 2694.2 °C in 2023). H_CTR varieties had superior hundred-grain weight (10.7 %) and grain number per cob (12.5 %). Aboveground biomass followed a logarithmic growth curve, with H_CTR varieties outperforming L_CTR throughout, especially at blister (R2, 29.0 %–31.8 %) and milk stages (R3, 9.0 %–12.6 %). This was due to earlier peak growth rates at R2 for H_CTR, while L_CTR peaked at R3. H_CTR also showed higher relative chlorophyll content (5.9 %) and net photosynthetic rate (14.1 %) at R2, though these declined at R3 (4.4 % and 13.0 %, respectively), underscoring their earlier photosynthetic advantage. The key mechanism by which H_CTR 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_CTR maize varieties are particularly well-suited for late showing in the rainfed dryland areas of the NCP. These findings provide a theoretical foundation and practical guidance for selecting high-yielding maize cultivars suitable for rainfed dryland areas similar to NCP.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"22 ","pages":"Article 102044"},"PeriodicalIF":4.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147483","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}

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}

These findings demonstrate that KK serves as an optimal sire line due to its strong additive genetic contributions, while FM and WL function effectively as dam lines through their maternal genetic effects.

The findings reveal that while both male and female farmers adopt improved soybean varieties, fertilizer, and herbicides, the intensity of adoption varies due to differences in socioeconomic constraints. Male farmers demonstrated slightly higher adoption rates across all practices, particularly for herbicide use. However, financial and market-related barriers, such as high input costs and distance to seed markets, disproportionately hindered female farmers' ability to fully integrate improved practices into their farming activities. The analysis indicates that the adoption of improved soybean varieties by male farmers was mainly influenced by income and pest/disease constraints, whereas female farmers were more affected by age, extension visits, and community tenure. Herbicide use among male farmers was driven by farm size and input costs, while for female farmers, it was influenced by education, input costs, and proximity to seed markets. Fertilizer adoption among male farmers was linked to income and farming experience, whereas female farmers' fertilizer use was shaped by farm size and financial constraints. Ordered probit regression results suggest that age negatively affects adoption intensity for both genders, but income and community tenure play a stronger role for men, while market access and cost barriers are more significant for women. Improving access to extension services can significantly enhance adoption rates, especially for female farmers who face higher input costs and limited access to seed markets. Targeted subsidies and credit programs tailored to smallholder farmers will help alleviate financial barriers, enabling both men and women to invest in essential inputs and expand production. Strengthening rural infrastructure, including better road networks and input market accessibility, will further reduce logistical challenges and support increased soybean cultivation.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"22 ","pages":"Article 102032"},"PeriodicalIF":4.8,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108027","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}
