The research was aimed at assessing the impact of growing technology with microbiological application and herbal extracts on dry matter content, starch and y ields, as well as vitamin C content in two potato cultivars, as compared to traditional fungicide - based and pest control technology , and to the variant without using bio - preparations and fungicides. The results of the study were based on the field experime nt conducted in 2014 – 2016 at in Uhnin (51°34' N , 23°02'E), slightly acidic soil. The experiment was performed by means of randomized blocks method, in dependent split - plot pattern, in three replicates. The 1 st order factor was the potato cultivars ( ‘ Vineta ’ and ‘ Satina ’ ), while the 2 nd order factor was six crop technologies. Organic and mineral fertilization of potato was uniform. The applied cultivation techniques using microbiological preparations, herbal extracts and fungicide applications contributed to a significant increase in the dry matter content, vitamin C, while did not significant influence on dry matter yield. Reaction of cultivars towards the bio - preparations used has varied.
