The aim of the study was to evaluate the influence of farming system and fertilizer rate on potato quality traits. Field trials were arranged under the conventional and organic growing conditions at State Priekuli Plant Breeding Institute. Two fertiliser rates were used in the conventional field. A tuber yield and starch content, as well as vitamins A and C in tubers, were detected. Results of the first research year showed a significant influence of genotype, growing system (organic and conventional), as well as fertilization rate, on tuber yield. The starch content and content of vitamin C in tubers were lower, if a higher fertilizer rate was applied. The starch content in tubers did not differ significantly between the organic and conventional growing systems. A trend to accumulate higher amount of vitamin C in tubers was observed under the organic growing conditions in comparison with conventional ones. The content of vitamin A in potato tubers was determined only by genotype, while the significant influence of growing conditions was not observed.
