The results of two years of research on the cultivation of various potato varieties in the Kirov region are presented. The observations were carried out in a long-term experimental hospital on drained lowland peat soil, where potatoes were continuously grown for more than 40 years without regard to varietal affiliation. In 2023–2024, experiments on the cultivation of three different potato varieties (Bellarosa, Red Sonya, Red Lady) were conducted at this hospital and a comparative assessment of the productivity of each of them was carried out. Potato varieties Red Lady and Bellarosa are not registered in the State Register for the Volga-Vyatka region, but are available for sale and distributed in the Kirov region, and therefore were chosen for the experiment. The timing of planting row crops in these soil and climatic conditions is set depending on the weather conditions of the year and the decrease in the groundwater level. When cultivating potatoes, energy consumption for tillage, planting, care and harvesting is one of the highest (40–43 GJ/ha) compared to perennial grasses (17–19 GJ/ha), however, taking into account the specific features of peat soils, it is possible to obtain good potato yields (160–260 kg/ha) under these conditions. According to the results of a comparative assessment of the chemical composition of tubers, yield, collection of feed units and exchange energy, early-ripening Red Lady potatoes turned out to be the most productive compared to Bellarosa and Red Sonya varieties. During the study period, the yield of tubers of the Red Lady variety was 260 c/ha, which is higher than the average yield in the Kirov region.
