Head Lyashchenko Sofia Anatolyivna, Кандидат сільськогосподарських наук Registration Date 19-12-2025 Organization Institute of Potato Science, National Academy of Sciences of Ukraine popup.description1 Improvement of the elements of varietal technology of growing potatoes by optimizing the fertilization system for changes in the natural and climatic conditions of Ukraine; study of the effectiveness of using the latest mineral fertilizers and growth stimulants depending on the biological characteristics of new potato varieties. popup.description2 Studies conducted in 2025 and based on the average indicators for 2023–2025 have established that the use of Calciprill®110 (400 kg/ha) + Euro Vive Pure AA Liquid (2.5 l/ha) – (option 6) and Magprill®80 (400 kg/ha) + Euro Vive Pure AA Liquid (2.5 l/ha) – (option 7) had a positive effect on the main biometric indicators of growth and development of the Misteria and Marfusha potato varieties. Options 6 and 7 provided maximum increases in germination, stem density, stem diameter, root system volume, number of stolons, and tubers. It was established that both the Misteria and Marfush varieties had the highest yield in options 6 and 7, which amounted to 36.6 and 37. 9 t/ha with an increase of 19.2 and 16.8 t/ha over the control, and 52.6 and 53.6 t/ha with an increase of 21.5 and 22.4 t/ha, respectively. The average yield for 2023–2025, depending on the products used, ranged from 17.3 t/ha (control) to 33.3 and 34.6 t/ha (options 6 and 7) for the Misteria variety and from 26.9 t/ha (control) to 43.1 and 43.8 t/ha (options 6 and 7) for the Marfush variety. The highest yield of tubers per bush was established in the sixth and seventh variants, both for the Misteria and Marfush varieties, 11.1 and 10.0 and 18.3 and 15.5, respectively. On average over the years of research, the yield of tubers in these variants was 11.8 and 11.7 for the Misteria variety and 16.3 and 15.0 for the Marfusha variety. Disease damage was determined and established: the highest damage in the first variant, both in the Misteria variety and in the Marfush variety: common scab – 7.4 and 9.4%, rhizoctoniosis – 2.5 and 2.9%, dry rot – 11.7 and 14.9%. The lowest incidence in the Misteria variety was found in variants 7 and 9, respectively 5.1 and 4.7% for common scab, 1.3% for rhizoctoniosis, and 8.6 and 7.7% for dry rot. Over the years of research, no complete correlation between the use of preparations and disease incidence has been established. Product Description popup.authors Serhii I. Kupriianov Andrii O.
