This thesis deals with the influence of foliar nutrition in grapevine with a particular focus on Fertileader Elite. The vineyard in the cadastre of the village of Mackovice was chosen for the establishment of the experiment. The preparation was applied on 18.7. 2018. The comparison of the two variants was based on uvological and analytical values. From the view of uvology, we found the weight of the grapes, the weight of one berry, the weight of the grapes from one bush and the total yield. The analytical values were mainly represented by sugar content, titratable acid content and assimilable nitrogen. The results were compared and then evaluated. In the nutritional variant, the yield increased significantly by up to 53.63%. The sugar content measurement was also based on the nutritional variant, with the sugar content higher by 9.72% than the control variant. On the other hand, titratable acids decreased by 8.36% in the nutrient variant. Thus there was an increase in yield and sugar content, but also a decrease in the titratable acid content. The difference between the nutrient variant and the control variant in the assimilable nitrogen content was not significant. The 2018 was very warm and dry in terms of yield and sugar content above average, the trial was heavily influenced by the year and conducted only once, it would be appropriate to try again in more consecutive years.
