Head Melnychuk Taras V., Кандидат сільськогосподарських наук Registration Date 02-01-2026 Organization Precarpathian State Agricultural Experimental Station of the National Academy of Agrarian Sciences of Ukraine popup.description1 Scientific and practical substantiation of the influence of the elements of cultivation technology to realize the productivity potential of new varieties of winter rapeseed of our own selection (Alisher, Vodogray, Darunok). popup.description2 Research has established that the application of mineral, foliar fertilization and plant protection products affects the formation of structural elements of the productivity of plants of winter rapeseed varieties. The largest number of pods 137 pieces per 1 plant was noted for the cultivation of the Darunok variety in the fertilization option N50P140K190+N150 + Bortrak (2.5 l/ha) + Brassitrel PRO (2.5 l/ha), the number of seeds in the pod 21.4 pieces and the weight of 1000 seeds - 3.92 g were also the largest, and on average for 2024-2025 132.5 pieces, 21.1 pieces, 4.01 g, respectively. The studies and their results show that the highest yield of winter rapeseed seeds 4.12 t/ha was provided by the Darunok variety for cultivation in the fertilization variant N50P140K190+N150 + Bortrak (2.5 l/ha) + Brasitrel PRO (2.5 l/ha), and on average during the years of research it was 4.05 t/ha. In the structure of the estimated cost of technologies for growing varieties of winter rapeseed at different levels of fertilization intensity, it was from 52.0 to 70.3%, means of protection from 12.3 to 54.1%, fuel and lubricants from 7.5 to 28.2%, and on average during the reporting period from 53.3 to 72.1%, respectively, from 9.89 to 44.6%, from 7.9 to 32.5%. The highest indicators of economic efficiency were obtained for growing rapeseed in the fertilization option N50P140K190+N150 + Bortrak (2.5 l/ha) + Brassitrel PRO (2.5 l/ha): the imputed net profit of the Darunok variety was 25.36 thousand UAH, the Vodogray variety 22.90 thousand UAH, the Alisher variety 21.26 thousand UAH, the level of profitability respectively 47%, 42%, 33%, and on average for 2024-2025 respectively 24.94 thousand UAH, 22.53 thousand UAH UAH 21.22 thousand, 48%, 43.5%, 41.0%.
