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.
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.
