  Global climate change, which is increasingly evident today, leads to significant fluctuations in the yield and quality parameters of sugar beet varieties, particularly due to its direct impact on semi-arid regions. Therefore, the adaptation capacity of varieties especially in the semi-arid areas of eastern regions and their responses to drought and temperature stress are of critical importance. This study was conducted during the 2022–2023 growing seasons to evaluate the yield and quality performance of ten sugar beet varieties (Seranada, Lider, Mohican, Terronova, Aranka, Turbata, Bernache, Setenil, Tisserin, and Chevalier) within a continental agro-ecological zone characterized by high altitude and a semi-arid climate. The results revealed significant differences among the varieties in terms of all examined traits. The highest root yield was obtained from Chevalier (95.30 ton/ha) and Mohican (94.17 ton/ha), while Tisserin produced the lowest (71.34 ton/ha). In terms of sugar yield, Terronova ranked highest (16.18 ton/ha), whereas Tisserin (12.44 ton/ha) and Setenil (12.34 ton/ha) showed the lowest performances. The Lider variety recorded the highest sugar content (18.22%), indicating its potential as a quality-oriented genotype. Overall, Mohican and Terronova demonstrated the most favorable responses under semi-arid conditions. These findings underscore the importance of regional variety testing for identifying high-yielding and high-quality sugar beet genotypes, especially in environments affected by altitude, climate variability, and soil characteristics.

  Yield Performance and Oil Composition of Safflower (Carthamus Tinctorius L.) Cultivars Under Semi-Arid Conditions in Northern Türkiye

  Cosar, Ibrahim; Gul, Volkan; Sefaoglu, Firat

  The shortage of vegetable oil in Turkey is escalating daily. Increasing the production of safflower oil seeds, which are particularly adapted to semi-arid climatic conditions, could reduce dependence on foreign sources for vegetable oil. In this study, the yield and quality characteristics of eight safflower varieties were evaluated under semi-arid ecological conditions in northern Turkey. Field trials were conducted over two years (2020–2021) with three replications, following the ‘’Randomized Block Experiment Design’’. Significant differences were observed between the varieties in terms of the examined parameters. The highest average grain yield (1730.9 kg ha⁻¹) was obtained from the Göktürk variety, the highest oil content (30.7%) from the Balcı variety, and the highest oil yield (470.1 kg ha⁻¹) from the Olas variety. The highest oleic acid content (50.14% ± 3.9) was obtained from the Koc variety, and the highest stearic acid content (2.68% ± 0.1) was obtained from the Hasankendi variety. The linoleic acid (77.71% ± 0.4) and palmitic acid (5.92% ± 0.1) ratios were found to be higher in the Dincer variety compared to other varieties. The research highlights the importance of genotypes in asparagus. It demonstrates that the Göktürk and Olas varieties stand out in terms of yield and yield components in semi-arid ecosystems. These results provide variety-specific information for regional adaptation in safflower breeding and under challenging climatic conditions.
