The effect of extra-root nutrition on sugar beet growth and development during the vegetation period was examined in field trials. Simultaneously, yield and technological quality of tubers were evaluated. Conclusively highest weight gains were noticed between 28th July and 12th August. By the end of the harvest, the weight of leaves was decreased to 550 grams per plant as the result of older leaves necrosis. The final leaf weight was in individual variants in the range of 373 to 778 grams per plant. The highest weight was found in the variant with Mg application (Magnitra L fertilizer). High dynamics of root growth was recorded from 1st July to 12th August and from 8th September to harvest. The highest final tuber weight (1,274 to 1,601 grams) was observed after Carbonbor K, Carbonbor and Bortrac fertilizer application, i.e. boron application varieties. The highest yield was reached after sodium nitrate application, while the lowest was in control group. Treated groups got in average better outcomes than control plants. Alpha amino nitrogen content was low, the lowest average values were determined after the application of fertilizer with high B content. Soluble ash content ranged from 0.33 to 0.42 %. The lowest one was in control group and the groups with B fertilizer application. MB factor value was positive in all groups. The highest quality sugar beet was harvested in the groups with high B application. After yield results evaluation, two relationships were determined; a very strong relationship (with r = 0,834**) between the MB factor and water-soluble ash values and a negative relationship (with r = -0,613**) between digestion and the MB factor.
