In this thesis the effect of foliar application of cytokinin to yield and qualitative parameters of poppy was observed. For the experimental part, two one-year experiments were conducted - small-plot experiment and pot experiment. Small-plot experiment had been designed in four variants: control, application of cytokinin in stage of beginning of upgrowth (BBCH 30) and stage before flowering (BBCH 61). Cytokininins were applicated in ratio of 2,75 g/ha. The inorganic plant analysis conducted after an application of cytokinins in BBCH 30 is due to their effect on the increase in dry matter to the impact of the increase in consumption of nutrients by plants. Cytokinins affected the branching poppy, which led to an increase in the number of capsules in the first variant (BBCH 30) of 11.5%, for the second variant (BBCH 61) of 46.2%. That resulted in increase of yield of 1.7, respectively 4.9 %, but not significantly. Yield closely correlated with the number of capsules, but not significantly Pot experiment in Mitscherlich's doses was designed in four variants: 1. control without application of cytokinins, 2. and 3. variant with application in stage BBCH 35, respectively BBCH 61 and 4. with double treatment (BBCH 35 + BBCH 61). The ration corresponded to 2.75 g cytokinin / ha in the 2. and 3. variants and 5.5 g / ha with split application in variant 4. It was observed the significant influence of cytokinins on yield of seed. While at variant with uniform doses of cytokinin seed production increased by 0.7 %, respectively 4.4 %, double application significantly reduced the yield by more than 50%. The HTS, the number and size of poppies contributed to yield. There was no observed effect of the application of cytokinins on the oil content in the poppy seeds.
