Мета. Встановити особливості формування врожайності та якості насіння сортів льону олійного (Linum humile Mill.) в умовах Західного Лісостепу України. Методи. Дослідження проводили впродовж 2020–2021 рр. на дослідному полі Хмельницької філії Українського інституту експертизи сортів рослин (с. Требухівці, Летичівський р­н, Хмельницька обл.). Сівбу здійснювали в другій декаді квітня, норма висіву насіння – 8 млн шт./га. Предметом досліджень були сорти льону олійного ‘Орфей’, ‘Світлозір’ і ‘Водограй’. Закладання дослідів, оцінювання матеріалу, фенологічні спостереження та біометричні вимірювання рослин, збирання врожаю виконували відповідно до «Методики проведення кваліфікаційної експертизи сортів рослин групи технічних і кормових на придатність до поширення в Україні». Показники якості насіння льону олійного визначали згідно з «Методикою проведення кваліфікаційної експертизи сортів рослин на придатність до поширення в Україні». Результати. Оптимальні умови Західного Лісостепу України сприяли своєчасному настанню фенологічних фаз росту та розвитку, а також несуттєвому варіюванню тривалості періоду вегетації (від 96 до 99 діб) рослин льону олійного. Їхню продуктивність оцінювали за такими показниками, як кількість коробочок і маса насіння з однієї рослини. За умови сівби 25 квітня та норми висіву насіння 8,0 млн шт./га найвищою врожайністю характеризувався сорт ‘Світлозір’ (1,45 т/га), найнижчою – ‘Орфей’ (0,8 т/га). Оцінювання за біохімічними показниками та визначення вмісту сирого протеїну, олії й жирних кислот (пальметинової, стеаринової, олеїнової, лінолевої, ліноленової, гондоїнової, ейкозенової та ерукової) здійснювали для сортів ‘Орфей’, ‘Світлозір’ і ‘Водограй’. Так, ‘Орфей’ характеризувався найбільшою кількістю білка в насінні – 24,15%; ‘Світлозір’ мав показник 22,74%; ‘Водограй’ – 22,26%. Високою часткою олії в перерахунку на абсолютно суху речовину відзначився ‘Водограй’ – 45,6%, що на 2,19% більше ніж в сорту ‘Орфей’. Уміст ліноленової кислоти варіювався від 45,703 (‘Орфей’) до 48,261% (‘Світлозір’), а ерукову протягом досліджень не виявлено в жодному з сортів. Висновки. Сорти ‘Орфей’, ‘Світлозір’ і ‘Водограй’ характеризувалися понад 35%­м умістом олії в насінні, що відповідає вимогам ДСТУ 7577:2014, та забезпечили якість товарної продукції льону олійного. | Purpose. To determine the peculiarities of yield and seed quality formation of varieties of linseed (Linum humile Mill.) in the conditions of the Western Forest Steppe of Ukraine. Methods. The research was conducted in 2020–2021 at the experimental field of the Khmelnytskyi branch of the Ukrainian Institute for Plant Varieties Examination (Trebukhivtsi village, Letychivskyi district, Khmelnytskyi region). Sowing was carried out in the second decade of April, the sowing rate was 8.0 million seeds per hectare. Subjects of the research were oil flax varieties ‘Orfei’, ‘Svitlozir’ and ‘Vodohrai’. The experimental design, evaluation of material, phenological observations and biometric measurements of plants, harvesting were carried out in accordance with the “Methodology for the qualification examination of plant varieties of the technical and fodder group for suitability for distribution in Ukraine”. The quality indicators of linseed were determined according to the “Methodology of qualification examination of plant varieties for suitability for distribution in Ukraine”. Results. The optimal conditions of the Western Forest Steppe of Ukraine contributed to the timely onset of the phenological phases of growth and development, as well as to the insignificant variation in the duration of the vegetation period (from 96 to 99 days) of the flax plants. Productivity was assessed using indicators such as the number of pods and the weight of seeds per plant. Under the condition of sowing on 25 April and the sowing rate of 8.0 million seeds per hectare, the highest yield was characterised by the variety “Svitlozir” (1.45 t/ha), the lo­west – ‘Orfei’ (0.8 t/ha). The varieties ‘Orfei’, ‘Svitlozir’ and ‘Vodohrai’ were evaluated by biochemical indicators and the content of crude protein, oil and fatty acids (palmitic, stearic, oleic, linoleic, linolenic, gondoic, eicosapentaenoic and erucic) was determined. Thus, ‘Orfei’ was characterised by the highest amount of protein in the seeds – 24.15%; ‘Svitlozir’ had an indicator of 22.74%; ‘Vodohrai’ – 22.26%. A high percentage of oil in the total dry matter was found in ‘Vodohrai’ – 45.6%, which is 2.19% more than in ‘Orfei’. The content of linolenic acid varied from 45.703 (‘Orfei’) to 48.261% (‘Svitlozir’) and erucic acid was not detected in any of the varieties during the study. Conclusions. The varieties ‘Orfei’, ‘Svitlozir’ and ‘Vodohrai’ were characterised by more than 35% oil content in seeds, which meets the requirements of State Standard 7577:2014 and ensures the quality of marketable oil flax products.

Seeds are a vector of genetic progress and, as such, they play a significant role in the sustainability of the agri-food system. The current global seed market is worth USD 60 billion that is expected to reach USD 80 billion by 2025. Seeds are most often treated before their planting with both chemical and biological agents/products to secure good seed quality and high yield by reducing or preventing losses caused by diseases. There is increasing interest in biological seed treatments as alternatives to chemical seed treatments as the latter have several negative human health and environmental impacts. However, no study has yet quantified the effectiveness of biological seed treatments to enhance crop performance and yield. Our meta-analysis encompassing 396 studies worldwide reveals for the first time that biological seed treatments significantly improve seed germination (7±6%), seedling emergence (91±5%), plant biomass (53±5%), disease control (55±1%), and crop yield (21±2%) compared to untreated seeds across contrasted crop groups, target pathogens, climatic regions, and experimental conditions. We conclude that biological seed treatments may represent a sustainable solution to feed the increasing global populations while avoiding negative effects on human health and ensuring environmental sustainability.

Magnetic or oxidation treatment of irrigation water can promote the transport of water and nutrients by the root system, improve the efficiency of water and fertilizer use and potentially increase yields. Hydroponic and field experiments were conducted to explore how irrigation with magnetized and/or oxidized water affects grain yield and water-use efficiency (WUE) in winter wheat with an emphasis on physiological changes in the root system. Hydroponic cultivation of winter wheat with pure groundwater and brackish water included the following treatments: control group (CK−G, CK−B); magnetization (GM, BM); oxidation (GO, BO); and the combination of magnetization and oxidation (G(M+O), B(M+O), G(O+M), B(O+M)). Field experiments only tested irrigation with various types of groundwater, including the control group (IG), magnetization treatment (IGM), oxidation treatment (IGO), and the combination of the two treatment methods (IG(M+O), IG(O+M)). Hydroponic cultivation revealed that the magnetic treatment and oxidation of both groundwater and brackish water can significantly improve the root vigor of winter wheat, i.e., improvements of 100.5–253.7% and 100.4–213.9% were seen in the groundwater and brackish treatment groups, respectively, relative to the control group. The root length density (RLD) of wheat increased by 67.6% (GM), 79.4% (GO), 7.5% (BM), and 40.0% (BO) relative to the respective control groups (CK−G and CK−B). Moreover, the root weight density (RWD) for BO and B(O+M) treatments improved significantly (66.7% and 55.4%, respectively) relative to CK−B. The maximal increases in root surface area density (RSD) were observed in treatments GO and B(O+M), which showed values 125% and 100%, respectively, higher than what was measured for the control groups. The root/shoot ratios of the GO and G(O+M) treatments improved significantly (by 75.3% and 62.0%, respectively) relative to CK−G. The results of field experiments showed that wheat in the IGO and IG(O+M) plots absorbed more water from the soil than wheat in the of IG plots (increases of 13.9% and 16.9%, respectively). Furthermore, the IGO and IG(O+M) treatments produced significantly higher grain yields and WUE than the IG plots, with IGO producing the maximum yield (11.7 × 10³ kg ha⁻¹) and IG(O+M) the highest observed WUE (30.3 kg ha⁻¹ mm⁻¹). Hence, the research provides clear evidence that the irrigation of winter wheat with magnetized and/or oxidized water can increase grain yields and WUE.
