Abstract
Sugar beet is one of the crops that currently generates the most income, but so far its yield is not at a high level. To obtain a high yield of royal beet roots, it is necessary not only to choose a hybrid, observe agricultural techniques, but also to establish optimal fertilizer application rates. An analysis of the literature data shows that the use of fertilizers increases the yield of royal beet root crops by 30-40%. In this regard, ensuring the production of sugar beet with high-quality seed material, based on the introduction of intensive seed cultivation techniques into the seed production process, is an important task that determines the development of the beet sugar subcomplex. The research results have shown the positive effect of mineral fertilizers on royal beet plants, on their growth and development. The dependences of NPK removal from the soil on the norms and doses of mineral fertilizers, the ratio of basic nutrients and crop yields were revealed. In the case of the use of fertilizers, the indicators of NPK release of root crops of summer mother beets were higher than in control ones: nitrogen - 3-5%, potassium - 2-4%, and no signifi-cant difference in phosphorus was observed. The volume of NPK release of Mother beets through the leaves was significantly higher and increased in accordance with the increase in the amount of fertilizer: nitrogen - 6-9%, phosphorus - 5-8%, potassium - 5-9 %.
