Abstract

The paper presents the results of the study on the influence of micronutrient fertilizers on chemical composition, market quality and keeping quality of beetroots. Two domestic fertilizers (Миком СР СО and Реаком NPK) and two foreign fertilizers (ESPO top and ESPO combitop) were used in this experiment. The fertilization of plants with the micro-fertilizers ESPO top and ESPO combitop was performed at a rate of 5kg/h at the phase of 3-4 and 6-7 leaves. In the same period, the crops were treated with the solution of 1% of Миком СР СО and Реаком NPK. The hybrid Detroit F1 was subject for study. The results of our investigations showed that the use of micronutrients affected positively market quality of beetroots and improved their chemical composition. The highest quantity of dry matter and sugars have been accumulated by the beetroots fertilized with Миком СР СО (1% solution in the phase of 3-4 and 6-7 leaves) – 17,6 and 7.8%, respectively. The use of Миком СР СО and ESPO top helped to improve keeping quality of beetroots, especially in the first four months. Thus, during this period, in the experimental samples of the beetroots treated with Миком СР СО the losses were minimal and the content of healthy samples was 95.9%, which is almost double compared to the control variant. However, after seven months of storage all the investigated beetroots showed a low storability in the conditions of uncooled basement storage.
