Safflower (Carthamus tinctorius L.) is a multipurpose oilseed crop that is tolerant to drought, saline, heat and cold conditions; and yields high quality edible seed oil. The objective of this study was to evaluate the effect of plant density and genotypes on oil content and fatty acid composition of safflower. A field experiment was conducted in the years 2015 and 2016, during winter and summer seasons. Treatments included five safflower genotypes and six plant densities. Genotype and plant density significantly interacted (P < 0.05) to influence oil content and fatty acid composition of safflower. Increasing plant density from 62,500 to 100,000 plants ha-1 significantly (P < 0.05) increased the oil concentration from 16 to 54%, depending on the interaction between genotype and plant density and genotype by environment (winter and summer seasons). However, as plant density increased from 100,000 to 200,000 plants ha-1, safflower oil content significantly (P < 0.05) decreased in all genotypes. The lowest and highest oil contents was produced by genotype ‘Gila’ planted at density 62,500 or 200,000; and ‘Sina’, ‘Pi 537 636’ at 100 000 or 125, 000 plants ha-1 in winter or summer, respectively. Fatty acid composition was significantly influenced by genotype and plant density interactions during the two growing seasons. The main fatty acids identified included linoleic, oleic, stearic and palmatic. There was a significant (P < 0.05) increase in linoleic acid content and a decrease in oleic, palmatic and stearic as plant density increased from 62,500 to 100,000 plants ha-1, depending on genotype or growing season. Genotype ‘Sina’ at 100,000 plants ha-1 produced the highest oil content and with high unsaturated fatty acid concentrations.

The results of long-term studies of the biological, morphological and phenological features of the introduced new culture of safflower in the Central, Volga and North Caucasus regions are presented. Optimum parameters of depth of seeding (5-6 cm), seeding rates (300-350 thousand pieces/hectare or 12-14 kg), ensuring high productivity, oil content and quality of seeds are established. For the first time, the relationship between moisture availability of vegetation periods with accumulation of oil content and a change in the fatty acid composition was established. Oilseed (in untreated seeds) in the regions was from 14,5 to 31,2%, in excessively wet 2013 – 6,4% in the Moscow region and 8,6% in the Saratov region. Fatty acid composition revealed a high content of oleic acid in Krasa Stupinskaya variety – 13,6-16,8%, linoleic acid – 68,5-75,7%. The yield of oil in the Moscow region was 240 kg/ha. The yield of Krasa Stupinskaya in the Moscow Region was 0,6 t/ha, the Rostov Region 0,8 t/ha and Saratov Region 1,2 t/ha, with an average weight of 1000 seeds, respectively, by regions: 40,0 g, 47,3 g and 40,9 g. The growing season for growing seeds was 105 days in the Moscow Region, 94 days in the Rostov Region and 95 days in the Saratov Region. It has been established that excessive moistening during the flowering and seed filling period increases the harmfulness of enzyme-mycosis seed depletion (EMIS) – biological injury during maturation (enzymatic stage), followed by the seeding of the seeds with the phytopathogen Alternaria carthami Chowdhury. In the breeding programs for productivity and oil content, it is recommended to use the varieties Moldir (Kazakhstan) and Krasa Stupinskaya (FGBNU VSTISP), the fatty acid composition of which is characterized by an increased content of oleic and linoleic acid, which is of particular value for storage and use for food purposes.

Soybean is a valuable protein and oilseed crop ranked among the most significant of the major crops. Field experiments were carried out in 2016–2019 in South-East Poland. The influence of soybean cultivars (Aldana, Annushka), nitrogen fertilizer (0, 30, 60 kg∙ha−1 N) and inoculation with B. japonicum (control, HiStick® Soy, Nitragina) on the content of fatty acids (FA) in soybean seeds was investigated in a three-factorial experiment. This study confirms the genetic determinants of fatty acid composition in soybean seeds and their differential accumulation levels for C16:0, C16:1, C18:1n9, C18:2, C18:3, and C20:0 as well saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acids. Increasing the rate from 30 to 60 kg ha−1 N did not produce the expected changes, suggesting the use of only a “starter” rate of 30 kg ha−1 N. Inoculation of soybean seeds with a strain of Bradyrhizobium japonicum (HiStick® Soy, BASF, Littlehampton, UK and Nitragina, Institute of Soil Science and Plant Cultivation–State Research Institute, Puławy, Poland) is recommended as it will cause a decrease in SFA and C16:0 acid levels. This is considered nutritionally beneficial as its contribution to total fatty acids determines the hypercholesterolemic index, and it is the third most accumulated fatty acid in soybean seeds. The interaction of cultivars and inoculation formulation on fatty acid content of soybean seeds was demonstrated. An increase in the value of C16:0 content resulted in a decrease in the accumulation of C18:1, C18:2, and C18:3 acids. The content of each decreased by almost one unit for every 1% increase in C16:0 content. The dominant effect of weather conditions on the FA profile and C18:2n6/C18:3n3 ratio was demonstrated. This suggests a need for further evaluation of the genetic progress of soybean cultivars with respect to fatty acid composition and content under varying habitat conditions.
