Producing Capacity of Safflower on Dark Brown Soils of the Northern Kazakhstan
Download this article as:
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 10th of May with seeding rate 0,25 million of fertile seeds per 1 hectare turned out to be economically advantegeous for years of research.
