Field experiments were conducted during the main seasons of 2022 and 2023 at the agricultural research station of National Research Centre, Nubaria, Egypt to investigate the effects of potassium nitrate (0, 20, 40, 60 kg K<sub>2</sub>O fed<sup>−1</sup>) (fed = feddan = 2.4 ha) and zinc sulfate (0, 25, 50, 75 ppm Zn) on growth, oil yield, nutrients components and chemical composition of sunflower. Results indicated that application of potassium nitrate has a promoted effect on chlorophyll content, growth parameters (Head weight, head diameter and 100 seed weight), protein content, oil yield as well as nutrient content under all applied levels. The data also showed that the highest significant increase occurred with the soil application of 40 kg fed<sup>−1</sup> potassium nitrate combined with 75 ppm Zn foliar spray. Meanwhile, the lowest values were obtained at the control treatment. Therefore, the current study detected that potassium soil addition at 40 kg K<sub>2</sub>O fed<sup>−1</sup>, besides foliar application with 75 ppm Zn are important to improve the growth, macro-micronutrient, seeds and oil productivity of sunflower crops. Oil yield and nutrient content exhibit a strong positive correlation, with a correlation coefficient of 0.903 for N, 0.94 for P, 0.962 for K and 0.966 for Zn. This indicates that a higher nutrient percentage is associated with higher oil content of sunflower. Study underscores the importance of comprehending the interplay between potassium and zinc treatments in sunflower plants to enhance growth, yield, and oil production effectively. Understanding these relationships can lead to optimized cultivation practices and improved outcomes in sunflower farming.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"10 2","pages":"Pages 79-86"},"PeriodicalIF":0.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143907930","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}

Compared to traditional methods, this approach is simpler, more efficient, and highly accurate. By comparing two sample preparation techniques, it was found that slicing better reflects the true vitamin E content than grinding, as it minimizes losses caused by mechanical pressure. 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. In contrast, the vitamin E content in the seed coat is considerably lower. Therefore, the optimized detection method minimizes seed coat interference during sample preparation, ensuring the accuracy of the results.

Given the consistent and strong correlation of these anatomical features with pod rot resistance and their high heritability estimates, the pre-existing resistance could be identified even in the absence of the disease, which is particularly valuable for fields where pod rot may not occur every year.

Even small pods or seeds and low number per plant has been regarded as the key factor for the low yield potential both in BW-resistant peanut germplasm lines and available released cultivars, whether the resistance is closely linked with key yield components remains unclear. In this study, the relationship between pod weight and BW resistance was analyzed by using a recombinant inbred lines (RIL) population derived from a crossing combination between a high yielding cultivar Xuhua 13 and a BW-resistant cultivar Zhonghua 6. From the experiments, it was found that the BW resistance was not significantly correlated with pod number per plant (PNP), hundred pod weight (HPW) and pod weight per plant (PWP) in the RIL population.

Brassicaceae encompass numerous taxa of special agricultural and food interest, such as those known as oilseed brassicas (OSBs). Among these group are crops for obtaining canola and mustard seeds, commonly used for oil and spices production, respectively. OSBs are of greater interest for food because they are rich source of vitamins and minerals, and have also a great antimicrobial, antioxidant and antitumor potential application. Therefore, the improvement of these plant species (or of their cultivation methods) may ultimately lead to an improvement in human food and, accordingly, human health. This progress could go hand in hand with the <em>Trichoderma</em> fungal genus, either based on transgenesis with some of their genes, or using these fungi to formulate and produce bioinoculants. In relation to transgenesis, the most widely studied are those based on <em>Trichoderma</em> genes encoding endochitinases and Kelch-like family proteins, in both cases to achieve an antifungal effect against pathogenic fungi. With regard to <em>Trichoderma</em>-based products, these can be aimed at promoting plant growth, protecting crops against pathogens by acting as biological control agents (BCAs), or even reducing contaminants in the soil, such as heavy metals.
