This study aimed to evaluate the effects of boron and zinc fertilizers, applied individually and in combination, on the productivity of newly developed domestic sugar beet hybrids in southeastern Kazakhstan. Two hybrids, Bolashak and Abulkhair, were treated with foliar applications of boron (YaraVita Bortrac150), zinc (YaraVita Zintrac700), and their combinations at various concentrations, alongside a basal dose of N₃₀₀P₁₅₀K₃₀₀. Treatments were applied at four key growth stages: 4–8 leaf stage, 10–12 leaf stage, leaf closure within rows, and between rows. The highest boron (47.0mg.kg⁻¹) and zinc (37.0mg.kg⁻¹) concentrations were found in Bolashak hybrid at row closure with Bortrac150 (1.5L ha⁻¹) and Zintrac700 (0.5L ha⁻¹). Boron uptake was generally higher than zinc, particularly by the Bolashak hybrid roots compared to the Abulkhair hybrid, especially when treated with Background + B + Zn10 at 647.5g ha-1 . The highest zinc uptake was recorded in the Abulkhair hybrid leaves with the application of YaraVita Bortrac150 (1.5L ha-1 ) and YaraVita Zintrac700 (0.5L ha-1 ), amounting to 384.3g ha-1 . To produce one ton of biomass, Bolashak required 1256.3g ha⁻¹ boron and 727g ha⁻¹ zinc, while Abulkhair needed 1153.9 and 751.2g ha⁻¹, respectively. The highest root yield (82.0t ha⁻¹), sugar content (18.1%), and sugar yield (14.8t ha⁻¹) were recorded in Bolashak. Abulkhair reached a maximum root yield of 80.9t ha⁻¹, sugar content of 17.9%, and sugar yield of 14.4t ha⁻¹ with combined B and Zn in N₃₀₀P₁₅₀K₃₀₀ + B + Zn10 treatment. These findings suggest optimal B and Zn foliar applications can significantly improve sugar beet productivity and quality under local agro-climatic conditions.
