In the experiment, we studied the efficiency of growing soybean varieties ‘Ustia’, ‘Cordoba’ and ‘Estafeta’, as well as the influence of the following technology factors: microfertiliser Yara Vita Mono Molytrac appliedin the budding stage (0.25 l/ ha); Yara Vita Mono Molytrac applied in the budding stage (0.25 l/ha) + in the flowering stage (0.25 l/ha); growth regulators (Biosil, Radostim). According to the research results, it was found that the best yield of ‘Cordoba’ variety was obtained with the application of Yara Vita Mono Molytrac in the budding stage + Radostim (3.03 t/ha), and Yara Vita Mono Molytracapplied twice in combination with Biosil (3.03 t/ha) or Radostim (3.07 t/ha). Similarly, in ‘Estafeta’ variety, the maximum yield was obtained for the combination of Yara Vita Mono Molytracin the budding stage + Radostim, and for application of Yara Vita Mono Molytracapplied twice in combination with Biosil or Radostim. The protein content was the bestin ‘Cordoba’ variety for treatment with Yara Vita Mono Molytracin the budding stage + Radostim (43.5%), and for application of Yara Vita Mono Molytracin the budding stage + at the flowering stagein combination with Biosil (43.3%) or Radostim (46.6%).However, the best treatments in terms of oil content in‘Cordoba’variety were the use of Yara Vita Mono Molytrac + Radostim (21.3%), and Yara Vita Mono Molytrac appliedtwice in combination with Biosil (21.5%) or Radostim (23.2%). The best productivity of soybean variety ‘Estafeta’ was under the combination of Yara Vita Mono Moly tracapplied twice and Biosil, which ensured oil content of 22.3%.
