An outdoor experiment was made to identify biologically active phyto hormone Green Cytokinin effect on seed yield, 'Fenja' variety summer rape crop bud formation stage spraying different concentrations of this product solutions. In the experiment the highest summer rape seed yield - 1.98 t ha"1 - obtained using product Green Cytokinin two times under 1.5 1 ha"1 norms. Product Green Cytokinin Use two times on summer rape growth stages BBCH 53-54 + BBCH 58-59 was most effective according to an experiment carried out tests.
