Research results on process development of safflower cultivation for oilseeds under dark brown soil conditions of the northern Kazakhstan were presented. Safflower response in yield to heat and moisture availability was determined. Features of yield formation and fat content in safflower seeds depending on sowing time and seeds application rate were researched. Optimum sowing time and seeds application rate were detected during research years. At all sowing times, yield and oil content in safflower seeds were increased with increase of seeding rate from 0.15 to 0.25 million of fertile seeds per 1 hectare, but with further increase in seeding rate, yield and oil content in safflower seeds were decreased. Sowing time 10 th of May with seeding rate 0,25 million of fertile seeds per 1 hectare turned out to be economically advantegeous for years of research.
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.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
