The article presents the results of research on creating a source material for breeding new high-yielding potato varieties adapted to the conditions of the southern part of the Volga-Vyatka region. The research was carried out in the Department of selection and seed production of the Chuvash research Institute. The soil of the experimental site is gray forest, heavy loam, of medium fertility. Field and laboratory studies were conducted using generally accepted methods. More than 150 varieties have been studied in the collection nursery. The selected samples are valuable material for further selection and are identified on the basis of productivity. As a result of studying potato varieties of different groups of ripeness, highly productive varieties were selected for using the source material: 3 varieties were selected for each group of ripeness after the yield of marketable potatoes; 4 varieties with an increased number of tubers were selected.
The effective methods of increasing the yield of potatoes in the application of liquid bioorganic fertilizer obtained after anaerobic processing of organic waste are considered. It is noted that the liquid bioorganic fertilizer does not have a negative impact when applied to the soil on the environment and to increase the content of heavy metals in the soil.

On the experimental basis of the Chuvash Research Agricultural Institute-a branch of the Federal State Budgetary Institution “Federal Agricultural Research Center of the North-East named after N. V. Rudnitsky “, the influence of microbiological growth regulators on biometric indicators, yield and its structural elements of seed plantings of potatoes of the Chaika variety was studied. The use of leaf nutrition preparations of the agrotechnology combine “Azur-Niva LLC” contributed to: an increase in the vegetative mass of potato plants by 42 %; an increase in the yield of marketable potatoes from one bush, the number of potato tubers increased by 6.8 pcs., and the mass of tubers by 95 %; an increase in potato yield was 32.8 %.
