The aim of the study was to evaluate the impact of the application of foliar fertilizers on starch production at potato growing. The literary review contains a general introduction to the topic and furthermore there is a summary of the existing development and production of potatoes both in the Czech Republic and abroad. The results were obtained from the one-year field experiment, during which two potato varieties with different lengths of the growing seasons were planted. It was a medium-early ripening variety Priamos and the late variety Dominator. In 2014 the one-year field experiment was established, during which the effect of the application of the solution of urea, Lignohumate and Energen Fulhum was evaluated compared with the variant without the application of foliar fertilizers. The tuber yield, number of tubers per plant, weight of tubers per plant, average weight of 1 tuber, starch yield and starch content were evaluated. The annual results indicated that the foliar fertilizers had on this year the positive effect on tuber yield, but the impact on the starch yield and content has not been confirmed. Both monitored potato varieties responded positively to the application of Lignohumate - by tuber enlarging. The Priamos Variety had an average tuber yield of 50.3 t/ha and the average starch content of 20.3%. In contrast the variety Dominator had the average tuber yield of 59.8 t/ha but lower starch content, in the average by 17.6%.
