The dissertation investigated on the base of smallparcelled land the production abilities of chosen varieties of potatoes with different lenght of vegetation period in conventional and ecological system. The aim was to evaluate the yield of the tubers, weight of tubers, number of tubers under bunch, number of tubers with a proportion of market value tubers, amount of starch and amount of nitrates on the base of reached results of one years field experiment based on ecological and conventional grown system. The chosen varieties were divided in germinated and non germinated variantions in small parcelled experiment. It was found out that content of nitrates was by both grown technologies under hygienic limit. The lower values were reached in ecological grown system. The determinated starch content of tubers did not prove the differencies between varieties and growing system and it was determinated by 14 %. The conventional technology was better evaluated by yielded elements. Very early variety Magda non germinated showed from chosen varieties enhanced yield of tubers in ecological grown system and it was defined to 87 % of conventional yield for determinated variety. The whole number of tubers in ecological system reached 82 % of conventional technology. Positive influence of germinated seedlings was proved by the yield of consuming tubers. Despite the ecological way of growing was less productive in all evaluated criteria it has very important position in potatoes offer in the market.
