Bulavina,T.M.
In a course of the research there was studied the effect of fungicides and micronutrients on the yield and quality of sugar beet (Beta vulgaris var. saccharifera). The research was realized in the conditions of the Republic of Belarus. As a result of realized research it was revealed that at high content of mtcronutrients in the soil, the application of Amistar fungicide without Polycom Beet micronutrient fertilizer gave the greatest yield of the hybrid of Klarina. It was shown that the fungicide use impacts root quality more significantly than micronutrient application. The sugar content in the roots depended on the use of trace elements and fungicides, increasing under the influence of these factors, in relative terms at 3.0 and 6.0-7.2%, respectively. Trace elements have contributed to an increase in potassium content and alpha-amino nitrogen in the roots of 1.5 and 8.8%, respectively, without affecting the content of sodium in them. Under the influence of decrease in the sodium content of fungicides and alpha-amino nitrogen in roots was at 17.9-21.4 and 9.5-18.9%, depending on the drug used. Fungicide MSW 733 decreased the potassium content of 5.5%, while the Abacus and Extra amistar increased the rate at 2.8-3.1%.
