A. V. YA. YURYEV NATIONAL ACADEMY OF AGRАRIAN SCIENCES OF UKRAINE popup.description2 Effects of new growth regulators, biologicals and micro fertilizers on growth and development of plants as well as on yield capacity and sowing characteristics of the sunflower parental lines Sh1010A, H720V and H526V and hybrids Romans and Maksimus were studied. A varietal response to the studied factors was established. Pre-sowing treatment of seeds or dual usage of certain growth regulators and biologicals, both separately and in combination with micro fertilizers, contributed to an increase in productivity of the sunflower paternal line H526V by 0.07-0.18 t/ha, and of the sunflower hybrid Romans by 0.13-0.30 t/ha, which allowed obtaining the additional profit of 10,400-26,037 and 360-938 UAH/ha, respectively, and provided their accelerated implementation into production. The most effective for pre-sowing treatment of seeds were the plant growth regulator Radostim and the biologic Polymixobacterin and, for additional spraying plants - the growth regulators Radostim and Treptolem Product Description popup.authors Клименко Ірина Іванівна Огурцов Юрій Євгенович Чернобаб Олександр Вікторович popup.nrat_date 2020-04-02 Close
