Еconomic assessment of growing strawberries underdifferent plant protection systems in the Right bank Forest-steppe of Ukraine

Abstract

The article presents the results of the studies during 2016–2020 on the effectiveness of growing garden strawberries of remontant varieties Murano and Vivara using various chemical preparations in the system of plant protection against pests in the Right Bank Forest-Steppe of Ukraine. It has been established that growing garden strawberries of Murano variety is more profitable than Vivara variety. On average during 2016–2020, the yield of Murano variety with the use of insecticides-acaricides was 33.22–33.44 t/ha and the yield increase was 16.48–16.70 t/ha. The yield of Vivara variety was 25.12–25.60 t/ha, and the increase in yield to control was 12.06–12.54 t/ha. The highest percentage of high-quality berries with a dry substance content of 12% was collected from Murano variety 48.2% using Apollo® (0.5 l ha) + Caesar™ (0.2 l/ha) + Mavryk™ (0, 6 l/ha), which is 2.2 times more than in the control and 8% than when using the reference plant protection system. Similarly, the highest percentage of high-quality berries of Vivaro variety (35.2%) was obtained with the use of insect-acaricide complex, which is 1.3 times more than the control. The studied protection systems (Masai®, 0.4 kg/ha + Biscaiia®, 0.8 l/ha; and Apollo®, 0.5 l/ha + Caesar ™, 0.2 l/ha + Mavryk ™, 0,6 l/ha) in terms of yield and a number of economic efficiency indicators were either at the level of the reference protection system (Sunmight®, 0.7 kg/ha + Mospilan®, 0.5 kg/ha) or slightly more cost-effective. With a slight increase in production costs for insecticides-acaricidal action, the level of profitability in the cultivation of Murano variety increased to 78.3–78.6% or 1.4 times, Vivara variety — to 71.4–72.0% or 1.6 times. The highest net profit at a low level of production costs was obtained by growing garden strawberries of both varieties using a set of preparations Apollo® (0.5 l/ha) + Caesar 0,2 (0.2 l/ha) + Mavryk™ (0.6 l/ha), which gives grounds to recommend the plant protection system for implementation.
