On average over the two years, the yield of hybrids Golkeeper, Azart, and Khoriv was highest when using pre-sowing mineral fertilization N16P16K16 and foliar feeding of plants in the 5-6 true leaf stage with the micronutrient Yarylo Super Nitrogen (4 l/ha) – resulting in yields of 3.23 t/ha, 2.90 t/ha, and 3.13 t/ha, respectively. The yields were almost at the same level with urea feeding (8 kg/ha) against the background of pre-sowing fertilization N16P16K16 – resulting in yields of 3.22 t/ha, 2.88 t/ha, and 3.09 t/ha.
