The influence of variable electromagnetic fields on enhancing the resource potential of potato variety Pechorsky in conditions of the Far North

The article highlights the effect of variable electromagnetic fields (VEMFs) on improving the productivity of the Pechorsky potato variety in the conditions of the Far North. The experimental study results on the effect of weak electromagnetic fields on the growth and development of potato are described relatively to the climatic conditions of the region. The studies were conducted in the Komi Republic in 2021–2025. The climate of the republic is characterised by severe weather conditions. The research methods included the treatment of tubers before sowing in a special mode 15/5 (15 minutes exposure, 5 minutes break within an hour) using an individual frequency spectrum. The following indicators were analysed as germination rate, growth intensity, and yield. By the obtained results, the exposure to PEMF accelerated the growth and development of plants, increased the number and size of the formed tubers.
