Economic and energy efciency of fungicides and microfertilizers in the cultivation of sugar beet hybrids

Abstract

The results of determining sugar beet hybrids economic and energy efciency technology growing depending on the use of fungicides and microfertilizers are presented. The research was conducted in 2020–2022 in the “Svitanok” Agrienterprise of Vasylkiv district, Kyiv region. Research was conducted with two sugar beet hybrids (Pushkin, Akatsia), three variants of microfertilizers (control, YaraVita Bortrac 150 (3 l/ ha), YaraVita Mancozin (1 l/ha)) and three schemes of fungicide application (Stefstrobin (0.6 l/ha) + Shtefozal (0.5 l/ha) + Shtilvet (0.1 l/ha); Tserkostef (0.5 l/ha) + Shtefstrobin (0.6 l/ha) + Shtilvet (0.1 l/ha); Cerkoshtef (0.5 l/ha) + Shtefozal (0.5 l/ha) + Shtilvet (0.1 l/ha )) were studied. The evaluation of the fungicides and microfertilizers economic efciency was determined according to the prices for the end of 2022 according to generally accepted methods. The technology of sugar beets growing is generally accepted for the zone of the Right Bank Forest Steppe, except for the methods that were put to study. It was established that in the structure of economic costs during the cultivation of sugar beets, a signifcant part is occupied by the use of mineral fertilizers – 23.7 %, fuel – 18.6 %, plant protection products – 16.3 %, seeds – 13.5 %. In the structure of energy costs, most of it belongs to fuel (27.8 %), mineral fertilizers (26.9 %), equipment (19.7 %) and labor costs (15.7 %). Energy costs for plant protection products and microfertilizers make 4.5 and 0.7 %. The Akatsia hybrid has higher proftability rates (53245.7 UAH/ha), proftableness (164.9 %) and energy efciency ratio (3.6) compared to the Pushkin hybrid (45462.2 UAH/ha, 147.6 % and 3.3). From an economic and energy point of view, the combined use of microfertilizers YaraVita Mancozin (1 l/ha) and fungicides Tserkoshtef, k. s. (0.5 l/ha) + Stefstrobin k.s. (0.6 l/ha)+ Stilvet (0.1 l/ha) is the most appropriate. Efciency, proftability and energy efciency ratio were 51491.3 and 60394.3 UAH/ha, 161.9 and 181.5 %, 3.58 and 3.94, respectively, for hybrids Pushkin and Acacia. Key words: sugar beets, fungicides, microfertilizers, hybrids, economic efciency, energy efficiency.
