Abstract A field trail was performed to study the impacts of soil tillage system and some organic and inorganic fertilizers treatments on sunflower performance and soil characteristics in the semi-arid region across 2015–2016 growing season. The tillage systems were (T1) conventional tillage, and (T2) reduced tillage while the fertilizer treatments were (F1) control, (F2) 20 t ha−1 farmyard manure, (F3) 40 t ha−1 farmyard manure, (F4) 20 t ha−1 farmyard manure plus 50:25:25 kg ha−1 NPK, (F5) 100:50:50 kg ha−1 NPK. The two-way entry (treatment) by tester (trait) biplot tool, described 84 % of the observed variability (68 % and 16 % by the first two principal components, respectively). The which-wins-where pattern, showed six vertex treatment (tillage system × fertilizer type) as: T1-F1 which had the highest values for bulk density; T1-F3 which had the highest values for days to maturity, organic matter and root depth; T1-F5 which had the highest values for soil phosphorus and harvest index; T2-F1 which had the highest values for mean emergence time; T2-F3 which had the highest values for soil potassium and achene yield; and T2-F4 which had the highest values for soil nitrogen. The ideal treatment pattern indicated that T2-F4 was the best treatment combination. We found that the best performance for sunflower achene yield was obtained with using reduced tillage system plus F3 or F4 fertilizer treatments. Finally, application no fertilizer or using only chemical fertilizers could not improve sunflower performance in both tillage systems.
摘要通过田间试验，研究了2015-2016年半干旱地区土壤耕作制度和一些有机和无机肥料处理对向日葵生长性能和土壤特性的影响。耕作制度为（T1）常规耕作和（T2）减少耕作，而肥料处理为（F1）对照，（F2）20 t ha−1农家肥，（F3）40 t ha−1农家肥，（F4）20 t ha−1农家肥加50:25:25 公斤 ha−1 NPK，（F5）100:50:50 公斤 ha−1 NPK。测试人员（特征）双批次工具的双向进入（处理），描述84 % 观察到的变异性（68 % 和16 % 分别通过前两个主要分量）。在哪种模式下获胜，表现为六顶点处理（耕作制度×肥料类型）为：体积密度值最高的T1-F1；T1-F3的成熟天数、有机质和根深值最高；土壤磷和收获指数最高的T1-F5；T2-F1具有最高的平均出现时间值；土壤钾和瘦果产量最高的是T2-F3；土壤氮含量最高的是T2-F4。理想的治疗模式表明T2-F4是最佳的治疗组合。研究发现，采用少耕制度加F3或F4肥料处理的向日葵瘦果产量表现最好。最后，在两种耕作系统中，不施肥或只使用化肥都不能提高向日葵的性能。

Abstract The main non-microbial cause of quality deterioration in lipid-containing food is lipid oxidation, the process in which, simplifying, unsaturated fatty acids react with molecular oxygen via a free radical mechanism. The use of substances with antioxidant properties during the manufacturing process can minimize the extent of lipid oxidation. This research aimed to determine the effect of selected essential oils on the quality and oxidative stability of sunflower oils. Sunflower oils were obtained by refining and cold-pressing and their quality and oxidative stability were studied during the different storage conditions: 20 °C and 5 °C at dark and with light exposure. Obtained results suggested that the antimicrobial and antioxidant properties of essential oils can positively affect the oxidative stability and consequently the quality of sunflower oils during storage, and implicate with further application of essential oils in the edible vegetable oil industry.

Abstract Downy mildew is one of the most important diseases of sunflower crop around the world caused by Plasmopara halstedii (Farl.) Berl.et de Toni. The aim of our study is the sunflower hybrid development with the durable resistance to downy mildew, combining one parental line with the most effective for the specific location major gene (Pl 15 for example) and the second parental line – with a high horizontal resistance to downy mildew. Experiments were conducted at All-Russia Research Institute of Oil Crops in 2016–2021. Experimental design was randomized blocks with three replications. CMS-lines with the highest level of horizontal resistance (VK 678, VA 732, VK 680, VK 934, VK 900 and new line SL 0516) were used as mother parents. Lines with Pl 15, resistant to all the downy mildew races were used as pollinators to create sunflower hybrids with durable resistance to downy mildew. A number of high-productive sunflower hybrids with durable resistance to DM (VK 732А × L 642-15, VK 732А × L 634-15, VK 680А × L 642-15, VK 680А × L 634-15, VK 934А × L 642-15 and VK 678А × L 634-15) were developed and tested.

Abstract The foliar fungal disease Septoria leaf spot is economically important for sunflowers. It develops most intensively during the wet and warm season. However, the genetic nature of sunflower resistance to Septoria leaf spot is still not clear. The purpose of our work was to identify some inheritance patterns of sunflower resistance to this disease based on the assessment of lines and hybrids of the first and second generations. The studied material was sown in 2020 and 2021 and subsequently grown on a stationary artificial infectious plot enriched with Septoria helianthi pathogen. The frequency of infection and the severity of infection of each sample were taken into account. The two-factor variance analysis revealed a significant influence of genotype on the frequency of infection in six sunflower lines and confirmed the effect of individuality of the response of individual genotypes to disease damage. It was shown that about 65 % of the total variation of the trait is due to the genetic nature of the line, and only a little more than 20 % and about 11 % – to the influence of the environment and the “genotype × environment” interaction respectively. Based on disease damage data in 2020 and 2021, the lines were classified as susceptible, moderately susceptible, moderately resistant and resistant. Differentiation of lines according to sensitivity to Septoria leaf spot made it possible to obtain hybrids with different manifestations of the trait in their parents. The nature of inheritance of infection frequency in F1 sunflower hybrids was determined by the degree of dominance. As a result, it was revealed intermediate inheritance, as well as positive and negative overdominance of the trait. The severity of infection by S. helianthi pathogen in F1 hybrids was inherited according to the type of parental form with greater resistance to the disease. F2 populations were found to inherit infection frequency from the more resistant parent, showing a proportion of infected plants similar to that of the more resistant line from a given cross combination. It has been shown that the frequency of infection of the F2 population with Septoria leaf spot can be affected by the severity of infection of F1 plant with the pathogen S. helianthi.

Abstract Compatible solutes control cell osmotic balance and compatible the cells’ metabolism whereas nano-particles have been introduced to increase crop production with inadequate knowledge. This investigation is done to evaluate the effects of application of salicylic acid, glycine betaine and nano titanium dioxide on sunflower. Measured traits were plant height (PH), leaf length (LL), chlorophyll content (CHL), number of seeds per head (NSH), 1000-seed weight (TSW), day to maturity (DM), husk percentage (HP), kernel weight (KW), percentage of empty achenes (PEA), head number per plant (HNP), grain yield (GY) and oil percent (OIL). Results indicated that the first two principal components accounted 92% of total variation of the treatment by trait (T × T) interaction and were used to generate a T × T biplot. All treatments were identified as the vertex treatments in polygon of TT biplot and the nano titanium dioxide treatment had high values for all traits expect PEA, HP and TSW. The nano titanium dioxide was identified as ideal treatment and GY and HNP were identified as ideal traits. The positive correlations between HNP and GY, and between OIL and KW; and near zero correlations between TSW and HP, and between TSW with DM as showed. Application of compatible organic solutes (glycine betaine and salicylic acid) had not any considerable improvement on traits while application of nano-titanium dioxide indicated considerably enhanced the yield and most traits of sunflower.

Abstract The article provides a comparative analysis of sunflower seed production in Ukraine, the EU and globally for the period from 2000 to 2021. The Ukraine’s share in the world sunflower production was found and analyzed. The analysis of the gross collection of sunflower seeds in the regions of Ukraine for two conditional periods (2000–2010 and 2011–2021) was carried out. Thus, during the researched period, the average yield increased from 1.04 t/ha in 2000 to 2.57 in 2021, i.e. by 2.5 times. It became possible due to the improvement and adaptation of cultivation technology and careful selection of sunflower hybrids that are better adapted to climatic changes. It was determined that the change in climatic conditions has affected the zones of comfortable sunflower cultivation in Ukraine. According to the yield index, during the first conditional period the central regions of Ukraine were in the lead (1.57 t/ha), and during the second period, the northwest regions of the country stepped up (2.83 t/ha). The above data suggest that the gradual change in sunflower cultivation technology and the search for new drought-resistant crop hybrids give hope that Ukraine will maintain its position in the world as a leader in the export of sunflower oil.

Abstract The main purpose of the paper included research on the variability of stearic acid content in the seed oil of the accessions of the V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK) sunflower genetic collection and to determine the mode of inheritance of the trait in F1 generation for choosing a hybrid breeding strategy. Gas-liquid chromatography of methyl esters and infra-red spectrometry were used for the estimation of fatty acid profiles. The inbred lines of I5 seeds LG31, LG32, LG33, LG34 and LG35 have been developed with high stearic acid content from 11.6 to 22.6%. Lines LG31 and LG32 showed relatively high values of oleic acid in the range of 56.7–70.5%. Lines LG33 and LG34 belonged to a group with a content of oleic acid in the range of 11.4–19.9%. An inbred line LG35 possessed increased content of stearic acid up to 11.6% on the low oleic background. The recessive type of inheritance of the mutations with high content of stearic acid in sunflower seed oil was verified. Both complete and incomplete dominance degree of standard content of stearic acid was found. Intermediate inheritance in F1 of this character was firstly distinguished in the cross of standard with high stearic acid line LG35.

Abstract The article is devoted to the analysis of production volumes and efficiency of sunflower cultivation in Ukraine. It is shown that sunflower occupies more than 70% of the total acreage under oil crops. Attention is focused on the fact that the dominance of sunflowers in the structure of the production of oil crops provides this crop with a special role in the agricultural market of Ukraine. The dynamics of sown areas, gross harvests and the level of productivity of sunflowers in Ukraine for the period 2018–2020 were analyzed. The effectiveness of sunflower production was studied in terms of forms of management of agrarian formations and by the amount of land in use. It has been established that the most effective cultivation of sunflowers is carried out by agricultural enterprises with a land area of more than 2 thousand hectares. Cost calculations and their structure for growing 1 ha of marketable sunflower in 2021 are presented. The volumes and structure of the directions of consumption of marketable sunflower seeds in Ukraine are shown. Practical recommendations for improving the process of sunflower production are proposed, taking into account the balance of supply and demand for marketable products.

This study examined the effects of Sangrovit®, a Macleaya cordata plant extract (MCE) preparation on feed intake, growth, blood chemistry, and tissue-residue levels of calves. Twenty male and 20 female calves (~5 d of age) were assigned to one of four daily Sangrovit® doses: 0.0 and 0.0 (CTL), 2.0 and 4.0 (D1), 5.0 and 10.0 (D2), and 10.0 and 20.0 (D3) g/calf in pre-weaning (5 to 49 d of age) and post-weaning (50 to 95 d of age) periods, respectively. Sangrovit® doses were fed in milk replacer pre-weaning and top-dressed on calf starter post-weaning. Milk replacer and calf starter intake was recorded daily. Body weight, hematology, and serum chemistry were measured at 5, 49, and 95 d of age. Calves were slaughtered at 95 d of age for MCE tissue residue analysis. Compared to CTL, D1 increased milk-replacer intake (4.90 to 5.09 L/day), but decreased calf starter intake pre- (0.65 to 0.53 kg/d) and post-weaning (3.42 to 3.20 kg/d). No Sangrovit® dose affected average daily gain. The hematology and blood chemistry of all treatment groups fell within the ranges of healthy calves. Results showed no adverse effects of MCE on health and growth performance of calves when fed up to 10.0 g/calf/day pre-weaning and up to 20.0 g/calf/day post-weaning.

Abstract General and specific combining abilities of three cytoplasmic male sterile and four restorer lines of sunflower were studied in a randomized complete block design with three replications under normal irrigation and drought stress conditions in Eslamabad-e-Gharb, Iran during two growing season (2019 and 2020). Drought stress reduced seed yield, oil yield, thousand seeds weight and head diameter by 21.9%, 18.1%, 14.3% and 11.5%, respectively. Line × tester analysis indicated that the effect of lines was significant for the number of days to flowering, plant height, grain yield and seed oil percentage under both normal and drought stress conditions. The effect of lines was significant for number of days to maturity and number of seeds per head under normal condition and for thousand seeds weight under drought stress condition. Contribution of lines × testers were higher than the variances of lines or testers for of most of all the studied traits indicating the major role of non-additive effects on expression of theses traits. R131 was differentiated with the highest positive general combining ability for grain and oil yield in both normal and drought stress conditions. Among the testers, AGK32 and AF81-222 had the highest general combining ability for grain yield under normal and stressed conditions, respectively. R131×AGK38, with grain yields of 4414 and 3457 kg ha-1 under normal and drought stress conditions respectively, had the highest specific combining ability for grain and oil yield under both conditions. The results of this study showed that the genetic materials and environmental conditions can affect the nature of gene effect and combining ability of sunflower parent lines and crosses.
