YIELDING CAPACITY AND OIL CONTENT IN SAFFLOWER IN NORTHERN KAZAKHSTAN
Results are given from studies on developing technologies for cultivation of safflower for seeds in the dry steppe zone of Northern Kazakhstan. Response of safflower to available heat and moisture was established. The features of yield formation and oil content of safflower seeds depending on sowing dates and seeding rates were studied. Through years of research was found the optimum sowing date (May 10) and the seeding rate of 0.25 million viable safflower seeds per ha. At all sowing dates, yields of safflower increased with increasing seed rate from 0.15 to 0.25 million viable seeds/ha and decreased with further increase in seed rate. For years of research was found that the sowing date of May 10 and seeding rate of 0.25 million viable seeds/ha turned to be cost-efficient. In this variant was obtained the lowest cost of oilseed production (365.5 rubles), the maximum profitability level (173.6%) and net income of 4004.3 rubles.
