“…According to research results (Murphy, 2016;Ergönül and Özbek, 2020), spring camelina has many positive qualities (early ripeness, drought resistance, resistance to some pests and diseases) that make it unique among oilseeds. This is the main reason why it aroused great interest in the world as an alternative to oilseeds (Ghamkhar et al, 2010;Prakhova et al, 2018).…”

“…Protective measures against the above-mentioned diseases should be aimed at preventing and reducing the number of harmful organisms. Their ecological basis is formed by agrotechnical methods, with the help of which conditions are created for good growth and development of plants, contributing to a decrease in their infestation by various harmful organisms (Prakhova et al, 2018). The chemical method is used in combination with agrotechnical methods and only when it is not possible to reduce the number of harmful objects to a level below the harmfulness threshold.…”

“…As a technical oil, it is used for the manufacture of drying oil, biodiesel, in medicine and perfumery. Camelina seed oil in foreign countries is used, first of all, as a source of biodiesel (Prakhova et al, 2018;Kurasiak-Popowska et al, 2018;Moser, 2010;Gesch, 2014). The agronomic value of spring camelina is explained by the fact that the culture is undemanding to temperatures, tolerates frosts up to 8-10°C during the germination period, at the same time, during the growing season it tolerates a lack of moisture and high temperatures, which allows it to be cultivated in a wide range of soils and climatic conditions (Gamayunova and Moskva, 2016;Tulkubaeva and Vasin, 2017;Ahmed et al, 2017;Sagirova and Vlasova, 2020).…”

Spring camelina is a promising oilseed crop for the dry steppe zone of Northern Kazakhstan. However, the expansion of its sowing areas is constrained by the lack of scientific research, especially on the phytosanitary state. The article presents the results of the study of fungi of the Alternaria and Fusarium genus isolated from the affected organs of spring camelina plants and provides measures to control them in the field conditions of the region. The research aimed to identify common diseases and determine their development and distribution under different backgrounds when treated with fungicides. To identify fungal strains, the method of determination of the direct nucleotide sequence of the intergenic transcribed region was used, followed by the determination of nucleotide identity with the sequences deposited in the Gene Bank international database, as well as the construction of phylogenetic trees with nucleotide sequences. As a result of the analysis, phytopathogenic strains belonging to Alternaria alternata, Alternaria tenuissima and Fusarium acuminatum were identified. During field studies, the development and spread of diseases under different background conditions of fungicide treatment versus control were analyzed. Of the products used, the Pictor fungicide (active ingredients: Boscalid 200 g/l + dimoxystrobin 200 g/l) showed high efficiency, compared with the Extrasolbiofungicide (Bacillus subtilis, strain H-13). The results of the study can serve as a basis for the development of chemical and biological control methods aimed at specific pathogens.

Winter camelina [Camelina sativa (L.) Crantz] is a potential third crop to diversify maize (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations in the upper Midwest. Although generally considered a low‐input crop, empirical evidence suggests that it responds to added nitrogen (N) fertilization. However, optimum agronomic N rates have not been extensively studied in the region. A study was conducted from fall 2018 to fall 2020 at three locations to assess the effects of N fertilizer application time (all N‐rate applied in spring and N‐rate split applied in fall and spring) and rates on biomass and seed yield, and quality of winter camelina. Nitrogen application time did not affect yields. Both biomass and seed yields were greatly affected by N rates at all locations. Nitrogen had minimal effects on the oil and protein content of seeds, although greater N rates were associated with a slight decrease in oil content and a slight increase in protein content. The number of branches and silicles per plant varied significantly with N rates in all locations. The seed‐to‐silicle ratio showed significant differences in two out of three locations. Residual soil N increased with increasing N rates. A fertilization rate of 67 kg ha−1 provided the highest camelina seed yield. While this study has determined the agronomic maximum rate for applied N, further economic analysis could provide comprehensive decision‐making for farmers.

The aim of this research is to assess the varieties of winter camelina in terms of productivity and adaptability in a contrast agroclimatic environment of the Middle Volga region and the region of steppe Crimea in 2016–2018. The climate of the Middle Volga region is moderately continental. The precipitation varies from 350 to 750 mm a year. The average year temperature is 5.3 °C. The climate of the steppe Crimea region is continental. The average year temperature here is 15.1 °C and the precipitation varies between 350 and 450 mm a year. In average the yield of different camelina varieties fluctuated between 1.59 and 1.83 t/ha, depending on the environment condition index (Ii -0.19–0.46). In the Penza region, the Kozir and Baron varieties gave the biggest yield with the productivity of crops equal to 1.80 and 1.83 t/ha respectively. In Crimea, the biggest yield was given by the Dikiy variety (1.74 t/ha). The variability of productivity is low at 7.4–10.1% and medium at 11.5–13.2%. The Baron variety has a low variation factor (7.4 and 11.5%) regardless of a cultivation region. All varieties had high stability which was 1.20–1.25 and 1.30–1.46 depending on a region. The Baron and Kozir varieties had the highest stability reaching 1.46 and 1.25 respectively. All varieties had a high index of stability for this crop, equal to 0.50–0.59. Camelina is tolerant of all stress factors and forms a stable yield in different cultivation conditions. All varieties showed a great ecological adaptivity and flexibility with the bi values equal to 1 and varying between 0.92–1.07. The most stable and flexible variety in the case of the Penza region is Baron (bi=0.92; σdr2=0.07) while in the region of Crimea it is Kozir (bi=0.99; σdr2=0.07). The Dikiy variety has high adaptivity parameters in both regions (bi=0.93–0.97; σdr2=0.06). The variance analysis showed that the share of “variety” factor influence is from 38.4% (the Penza region) to 39.2% (Crimea). In the variety-region relationship the influence of a variety is 40.6%. The share of “years” factor influence is 21.7–24.6%, depending on a region.
