The efficiency of micronutrient fertilizers, particularly boron and zinc, on the productivity of domestic intensive sugar beet hybrids in the southeastern region has not been sufficiently studied. In modern agronomic technologies for sugar beet cultivation, achieving high yields is impossible without the application of micronutrients through foliar feeding alongside macronutrients. The objective of this study was to examine the impact of boron and zinc fertilizers, as well as their combinations, on the productivity of new domestic sugar beet hybrids. The highest accumulation of boron was observed in the Bolashak hybrid at the row closure stage. This was recorded at 47.0 mg/kg when YaraVita Bortrac 150 (1.5 L/ha) and YaraVita Zintrac 700 (0.5 L/ha) were applied together. The maximum zinc concentration was also observed in the Bolashak hybrid at the same growth stage, reaching 37.0 mg/kg under the same fertilization conditions. Boron was excreted in greater quantities compared to zinc, and the root crops of the Bolashak hybrid accumulated more boron than those of the Abulkhair hybrid. The highest recorded value was observed in the Background+B+Zn10 treatment, reaching 647.5 g/ha. Zinc excretion was most pronounced in the leaves of the Abulkhair hybrid, reaching 384.3 g/ha under the application of YaraVita Bortrac 150 (1.5 L/ha) and YaraVita Zintrac 700 (0.5 L/ha). For the formation of 1 ton of root crops and leaves, the Bolashak hybrid required 1256.3 g/ha of boron and 727.2 g/ha of zinc, while the Abulkhair hybrid required 1153.9 g/ha and 751.2 g/ha, respectively. In this variant, the highest root yield of the Bolashak hybrid was 82.0 t/ha, with a sugar content of 18.1% and a sugar yield of 14.8 t/ha. The highest yield of the Abulkhair hybrid was 80.9 t/ha when YaraVita Bortrac 150 (1.5 L/ha) and YaraVita Zintrac 700 (0.5 L/ha) were applied. The sugar content in the Background+B+Zn10 and Background+B+Zn5 treatments was 17.9%, while the highest sugar yield (14.4 t/ha) was recorded in the Background+B+Zn10 treatment.
