ECONOMIC EVALUATION OF ELEMENTS OF WINTER RAPE CULTIVATION TECHNOLOGY IN THE CONDITIONS OF RIGHT-BANK FOREST-STEPPE

In the global agricultural market, winter rapeseed (Brassica napus L.) retains its leading position as a valuable and profitable oilseed crop with wide food, fodder, technical and bioenergy use. The article presents the results of scientific research conducted during 2022–2024 on typical black soil in the Forest-Steppe zone of the Right-Bank Ukraine with winter rape. The yield of three mid-season hybrids of winter rape was determined, which influenced the indicators of economic efficiency of crop cultivation. The results indicate a high economic evaluation of winter rape hybrids - InVigor 1030, Exception and Mercedes. It was found that the production costs of growing and obtaining rapeseed seeds depend on mineral nutrition (44.4%), pesticides (25.1%), soil cultivation (11.5%), seed cost (7.0%), fungicidal plant protection (5.5%) and the pricing policy of the marketing year. The cost of production is significantly higher than the production costs of growing and harvesting. The highest conditional net profit was obtained from the hybrid Exception on plots with N140P40K40 (background) + Yara Vita Brassitrel Pro, 2.0 l/ha (VVSN 31), which is 41940 UAH/ha. The combination of mineral nutrition with fungicidal treatment of plants in the flowering phase (VVSN 65) with Piktor 0.5 l/ha provided 59370 UAH/ha of net profit, and Propuls 0.9 l/ha - 57780 UAH/ha. The InVigor 1030 hybrid with the application of mineral fertilizers at the rate of N140P40K40 (background) + Yara Vita Brassitrel Pro, 2.0 l/ha (VVSN 31) provided 41605 UAH/ha of conditional net profit, and in combination with spraying in the flowering phase (VVSN 65) with Piktor 0.5 l/ha - 59035 UAH/ha and Propuls 0.9 l/ha - 57445 UAH/ha. The highest level of profitability for the InVigor 1030 hybrid is 151.3%, for the Exception hybrid - 150.1% and for the Mercedes hybrid - 138.3%.
