Assessment of the efficiency of the application of fungicides and microfertilizers in sugar beet growing in the forest Steppe of Ukraine

Abstract

The results of research on determining the effectiveness of using microfertilizers and fungicides on hybrid sugar beet crops are given. Research was conducted in 2021-2022 at the experimental field of Bila Tserkva National Agrarian University. In the experiment, sugar beet hybrids were studied: Libero and Margarita KWS; Microfertilizers: control without their use, Florenta beet (1.5 l/ha), Intermag beet (2 l/ha); Fungicides: control (without their application), Alto super 330 EC (0.5 l/ha), Amistar Extra 280 SC (0.6 l/ha), Styer 500 (0.5 l/ha). It was established that the highest yield of root crops and the coefficient of energy efficiency (Сее) in the sugar beet hybrids Libero and Margarita KWS was obtained on the variant with the use of the microfertilizer Intermag beet (2 l/ha) and the fungicide Amistar Extra (0.6 l/ha) – 52.1 і 58.3 т/га та 3.2 і 3.6, respectively. The use of fungicides allows you to increase the sugar content by an average of 0.8–1.2%, microfertilizer Florenta beet (1.5 l/ha) by 0.6%, and microfertilizer Intermag beet (2 l/ha) by 0.8%, compared with control variants. The best indicators of the technological qualities of sugar beet root crops were on the variants of combined application of microfertilizers and fungicides, while the conductometric ash content was the lowest, and calculated sugar content and dry matter content were the highest.
