From 2014 to 2024, soybeans have been the most popular crop in Kazakhstan's agriculture, especially in the northern grain-growing regions. However, in terms of the yield of this crop, Kazakhstan lags behind the largest-producing countries because of the spread of diseases caused by fungi, which lead to lower yields and seed quality. Therefore, the main objective of the study was to identify fungal pathogens affecting soybean crops in the forest-steppe zone of North Kazakhstan, with a focus on isolating and characterizing strains of the Alternaria genus. To identify the fungal strains, the method of determining the direct nucleotide sequence of the internal transcribed spacer region was used, followed by the determination of the nucleotide identity with sequences deposited in the international GenBank database, as well as the method of constructing phylogenetic trees with nucleotide sequences. Fungal isolates were obtained from infected soybean tissues, cultured on potato dextrose agar, and identified through direct sequencing of the ITS region and partial sequencing of the TEF-1α and Tub2 genes, followed by BLAST analysis and phylogenetic tree construction. As a result of the analyses, the authors identified a phytopathogenic strain of Alternaria tenuissima. The analyses revealed that the isolates belonged to Alternaria tenuissima, confirmed through both sequence identity and phylogenetic analysis. The identification of Alternaria tenuissima as a soybean pathogen provides essential data for the development of effective disease management strategies in Kazakhstan’s soybean production.
Influence of Seed Protectants on Fungal Pathogens of Lentil Seeds (Lens Culinaris) Against Different Cultivation Technologies in North Kazakhstan
International Journal of Agriculture and Biosciences, 2025
The study aims to investigate the influence of biological (Seedspor S) and chemical seed protectants (Piligrim, s.c.) on seed pathogens under different lentil cultivation technologies.The research gives evidence of the high efficiency of a comprehensive application of seed protectants, with the degree of seed infestation decreased by two or three times compared to the control variant.The integrated treatment demonstrates the lowest degree of seed infestation and the highest laboratory germination rate, vigor and field germination rate.In inhibiting and suppressing the spread and development of Fusarium ssp.root rot, the biological seed protectant Seedspor S is less effective than the chemical seed protectant Piligrim, s.c.The no-till cultivation technology provides greater intensiveness of inhibition and suppression, while the traditional technology shows lower intensiveness.Over the years of cultivation, the highest yield was obtained with the comprehensive application of the seed protectants (Piligrim, s.c.+ Seedspor S).

The study was carried out in 2021-2022 in the dry steppe zone of Northern Kazakhstan. The object of the study was the Kustanaysky yantar oilseed flax variety. Flax is a promising crop for this zone and requires an in-depth study of the diseases affecting it. The study aimed to evaluate the effect of Seedspor W and Olymp SC protectants on the seed infection pathogens, Fusarium ssp. and Colletotrichum ssp. against the background of different technologies of flax cultivation. Studies showed the high effectiveness of the complex use of protectants, where the degree of seed contamination decreased by two to three times compared to the control variant. By this variant, the authors obtained the lowest indicator of the degree of seed contamination (2-6%), high laboratory germination (90-95%), germination energy (79-89%), and field germination (70-87%). When restraining and suppressing the spread and development of root rot of Fusarium ssp. and Colletotrichum ssp., Seedsport W bioprotectant was inferior in efficiency to the Olymp SC chemical protectant. During the plant vegetation period, the prevalence and development of Fusarium wilt and anthracnose were more intense with no tillage, while less intense by traditional tillage. Over the years of the study, high yields were obtained in the variant with the integrated use of protectants (Olymp SC + Seedspor W + Akiba WSC) and averaged 7.1 c/ha, which was 3.9 c/ha more than the control variant.

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.

The article presents the results of the 2014-2015 studies on seed yield and the physicochemical and fatty acid composition of Akmay grade safflower oil cultivated at the experimental plot of LLC "Farmer 2002", Astrakhan district, Akmola region, Kazakhstan. The peroxide and acid number was determined with the titrimetric method with visual indication, and the iodine number was calculated as well. The fatty acid composition of oil was studied using the gas chromatography method. Up to 12 fatty acids were detected in the composition of total lipids. The highest content of fatty acids in the composition of safflower seed oil triglycerides was observed in unsaturated linoleic acid (82.7%). During the years of research, the weather conditions greatly influenced the seed yield and the physicochemical quality of safflower oil. Conclusions about future use of this variety as raw material for producing edible vegetable oil were drawn.

Objective: This study was conducted to identify the impact of various soil preparation technologies and seed application rates on crop yield and dietary value of lentil grown in the dry steppe zone of North Kazakhstan. Characteristics of crop and grain quality of different lentil grades as a function of seed application rates and various soil preparation technologies were studied. Materials and Methods: Three lentil grades, Vekhovskaya, Canadian Red and Wice Road, were sown at an application rate of 2.0, 2.2 or 2.5 million viable seeds ha–1. Field and laboratory experiments were conducted in accordance with the "methods of the state strain testing of crops". Results: The productivity level of the different lentil grades varied depending on varietal features and lentil seed application rates that ranged from 11.6-18.9 dt ha–1. All lentil grades in this study had excellent cooking qualities that scored between 4.1 and 4.8 out of 5. In terms of the economic efficiency, the highest efficiency was seen with low seed application rates. Conclusion: The best technology for lentil cultivation in North Kazakhstan involves minimal soil preparations and low rates of seed application.
