The effects of foliage nutrition facilitate efficient and immediate supply of nutrient needs during the vegetation period. The objective of this thesis is to assess the effects of foliage application of magnesium sulfate and urea for potatoes, that are intended for processing into starch production. There were two sorts of potatoes with different vegetation period under study, an early variety called as Bernard and semi-late variety called as Ornella. The foliage fertilizers were applied in three different variants. In the first variant the sorts of potatoes were fertilized by solution of magnesium sulfate, in the second variant by solution of urea and in the third variant the solution of magnesium sulfate and urea was used. The assessment of the experiment consists of yield on tubers, contain of the starch, yield on starch, the average amount of tubers per tuft, the average weight of tubers and profitability of used foliage fertilizers. In the year under the study the increased yield on tubers and on starch was detected in all three used variants. Both sorts of potatoes showed the best results when the solution of bitter salt and urea was applied. The increased yield on starch was reached through the increased yield on tubers preserving the high contain of starch. The yield of starch increased by 8 % in the semi-late variety of potatoes Ornella. The early variety of potato Bernard showed the increase of yield on starch by 14%.
