According to the results of the studies conducted in 2024 and 2025, more favorable conditions for the growth and development of the hybrids Golkeeper, Azart, and Khoriv were created by applying mineral fertilizers at a dose of N16P16K16 at sowing, along with foliar feeding of plants with the micronutrient fertilizer Yarylo Super Nitrogen (4 l/ha) or urea (8 kg/ha). 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.
