The study evaluated the effect of biological preparations on preserving the technological quality of sugar beet roots of the hybrid Augusto during long-term storage under commercial clamp conditions. The experiment was conducted from 31 October 2025 to 15 January 2026 and included 11 treatment variants with biological consortia, commercial bioproducts, liming, and an untreated control. The treatment factor significantly affected weight loss, sucrose content, digestion parameters, and root rot incidence (p<0.05). Biological treatments reduced total weight loss by 1.1%-2.7% compared with the control. The highest efficiency was recorded for Consortium 6, which ensured the lowest weight loss (1.20%), the lowest root rot incidence (0.60%), the highest sucrose content (18.35%), and the lowest accumulation of dextran and levan. The results confirm that biological post-harvest treatment is a promising tool for stabilizing sugar beet quality and reducing storage losses under industrial clamp storage conditions.
