Overall, drought stress resulted in a significant reduction in most morpho-physiological traits. In the principal component analysis (PCA), the first two components explained a substantial portion of the variation in both control and drought conditions, facilitating the classification of the genotypes into two distinct groups. Additionally, twelve drought stress indices further categorized the genotypes, with the first two components accounting for the majority of the variation (99.45%). Notably, the Nilofar, Nima, Nafis, and Shirali cultivars were grouped together under both control and drought conditions, exhibiting the highest grain yield.

However, the impact of ARC microbial inoculants on different resistant varieties of <em>A</em>. <em>flavus</em> remains unclear. In this study, we screened peanut varieties that were resistant and susceptible to <em>A. flavus</em> and evaluated their nodulation ability and growth performance after ARC microbial inoculants treatment in the field. The results demonstrated that the nodule number and nitrogenase activity of both varieties significantly increased after ARC microbial inoculants treatment, with the highly susceptible variety AH24 showing a greater increase. For photosynthetic parameters, both varieties also increased after ARC microbial inoculants treatment, but the increase was greater in the moderately resistant variety AH1 than in the highly susceptible variety AH24. Finally, we found that the yield and yield-related traits of the moderately resistant variety AH1 were better than those of the highly susceptible variety AH24. After ARC microbial inoculants treatment, the yield traits of both peanut varieties still increased significantly, but the degree of increase of the moderately resistant variety AH1 was smaller than that of the highly susceptible variety AH24. In addition, the abundance of <em>A. flavus</em> in the rhizosphere soil of the two varieties significantly decreased after ARC microbial inoculants treatment, with no significant difference between the varieties. These results indicated that ARC microbial inoculants exert differential effects on the nodulation and growth of different resistant peanut varieties and have a better effect on highly susceptible varieties. These results provide a solid theoretical basis for the efficient use of ARC microbial inoculants in the field of peanuts in the future.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 2","pages":"Pages 109-117"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221653","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}

While crops need sulphur in slightly lower amounts than phosphorus, maintaining optimum sulphur levels is crucial for oilseed yield and quality. Factors such as sulphur dynamics, impact of deficiency, application methods, and climate change must be addressed to improve agricultural practices. In South Asian countries like India, Pakistan, and Bangladesh, oilseeds are vital to the agricultural economy, supporting food security, livelihoods, and economic growth. However, climate change, marginal land cultivation, and a shift to more profitable crops like wheat and maize have led to a decline in oilseed productivity. Sulphur is particularly important for vital plant functions, including protein synthesis, chlorophyll formation, and resistance to abiotic stress. Proper management of sulphur can significantly enhance the yield, oil content, and seed quality. Sulphur fertilization improves crop resilience to pests, diseases, and environmental stresses, resulting in healthier plants. To optimize oilseed production, best practices for sulphur management like integrated nutrient management, regular soil testing, and the strategic application of sulphur-enriched fertilizers must be adopted. Despite its significance, many South Asian soils suffer from sulphur deficiency due to inadequate replenishment and reliance on high-analysis fertilizers. By enhancing sulphur availability, oilseed producers can significantly increase crop yields, improve oil content, and promote overall plant health, contributing to the agricultural economy and food security in the region. This manuscript aims to evaluate the critical role of sulphur in enhancing the yield, oil quality, and stress resilience of oilseed crops in South Asia.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 2","pages":"Pages 118-130"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221654","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}

The method demonstrated robust stability and accuracy in both repeatability tests and spiked recovery tests, showing no significant differences compared to the national standard method. The study revealed that the cotyledons of peanuts are the primary storage site for vitamin E, being rich in γ- and α-tocopherols, which together account for over 90°% of the total vitamin E content.
