Abstract The article presents the results of the research about the effect of combined application of complex microfertilizers and fungicides on yield and biochemical parameters of red beet root in the forest-steppe conditions of the West. experiments have shown that the application of ADOB complex microfertilizer macro + micro with fungicides Topsyn M and Impakt, provided the highest yield of root beet of Harol’d red beet - 62,0-62,2 t / ha and Kestrel variety - 75,4-77,4 t / ha, the increase was Harol’d - 20.4% and Kestrel - 21.7% compared to the control. When Avanhard R Buryak, Intermah-buryak and Sani Miks were introduced with fungicides together, the yield of red beet root was lower, namely, 55.50-60.10 t / ha in the Harol’d variety and 70.30-73.20 t / ha in the Kestrel variety. In general, the development and prevalence of the disease were more intense in the Topsyn M variants than in the Impakt fungicide variants which undoubtedly testifi es to the higher effi cacy of this fungicide. For an average of three years, with the application of fungicides, the yield increase compared to the control on variants without microfertilizers was 2.6-3.4 t / ha in the Harol’d variety and 5.6 t / ha in the Kestrel variety. The introduction of micronutrients in foliar feeding Avangard R Beetroot, Intermag-Beetroot, Sani Mix and ADOB macro + micro contributed to the increase of dry matter content in Harold root crops: 14.7; 14.6; 14.8 and 15.0%. A similar pattern was observed in the application of foliar feeding of Kestrel microfertilizers, namely 15.5; 15.7; 15.7 and 15.8%, respectively. Co-application of microfertilizers with fungicide Impact of 0.25 l / ha in the Harol’d variety increased the solids content by 2.7- 8.3% and Kestrel varieties by 0.6-3.9%. A similar scheme for the use of microfertilizers with the use of Topsyn M with the application rate of 1.2 l / ha provided a dry matter content of 14.8-15.6% in the Harol’d variety, which is 6.8% higher compared to without the introduction of fungicides, and in the Kestrel variety at the level of 15.6-16.0%, which is 3.2% higher respectively. The highest content of sugars was observed in the variant, where foliar ADOB macro + micro fertilizers were additionally applied together with the fungicides Impakt and Topsyn M in the Harol’d variety - 8.5%, which is 1.6% higher than the control variant, in the Kestrel variety (8 , 9%) which is 0.4% higher. Therefore, it can be said that the variety Kestrel showed only a tendency to increase the amount of sugars. The highest content of betanin in the non-fertilizer version was accumulated in Harol’d root crops (292.8 mg / 100 g crude weight). In Kestrel root crops, their number was at the level of 231.5 mg / 100 g of crude mass, which is much less than the Harol’d variety. Fertilizer application increased the content of betanin. However, the combined application of microfertilizers and fungicides contributed to their significant increase in the root crops of the two cultivars under study. Foliar ADOB microfertilizer macro + micro in combination with fungicide Impakt provided the highest betanin content of 352.5 mg / 100 g of crude mass in the Harol’d variety, and 270.9 mg / 100 g of crude mass in the Kestrel variety. A slightly lower level of betanine was in the variants with the application of Topsyn M fungicide - 350.3 and 267.3 mg / 100 g of crude weight, which is 19.6% and 15.5% above the control.
