Abstrakt: The goal of the study is to determine the effectiveness of foliar fertilization with chelated and humate fertilizers in sugar beet crops under various methods of primary tillage. The work was carried out in 2019–2021 in Voronezh oblast. The experiment was designed to consider the following variants: tillage system (factor A): moldboard (deep plowing to a depth of 30–32 cm); no-till (deep flat-cutting preparation to a depth of 30–32 cm); hybrid (factor B): RMS 120 (VNIISS) and Mitica (Lion Seeds Ltd.); foliar fertilization with micronutrient fertilizers (factor C): without micronutrient fertilizers; micronutrients in the chelated form of Zdraven'-aqua; and micronutrients in the humate form of Biohumus. The soil is leached heavy loamy chernozem. The arable layer has 5.3–5.6% of humus, 128–155 mg/kg of mobile phosphorous, 91–136 mg/kg of potassium, and pHKCl at 6–6.18. The maximum yield of beet roots was recorded under the conditions of moldboard soil preparation with foliar fertilization with chelated fertilizer in the RMS 120 hybrid (42.8 t/ha) and humate fertilizer in the Mitica hybrid (51.2 t/ha). The best quality was received in the domestic hybrid with application of chelated fertilizer (sugar degree exceeded the control by 0.26% with the reduction of nonsugar molasses-forming components and improvement in sugar-recovery rate by 0.63%). In the Mitica hybrid, the best results were obtained under the same soil preparation method with humate fertilizer; specifically, an increase in sugar degree by 0.41% and percentage recovery by 0.59% with reduction in levels of all molasses-forming nonsugars compared to the control. The foregoing fertilization proves to be the most efficient in combination with the moldboard soil preparation. [ABSTRACT FROM AUTHOR]
