This thesis discusses the use and effectiveness of fertilizers VIVE series of viticulture. For the experiment were selected white grape variety Chardonnay. This work includes four variants. Option 1 is the control and treatment without fertilizer. In Option 2 was used VIVE Super NPK fertilizer, in Option 3 it was fertilizer VIVE Super Ligno. In Option 4 was again used fertilizer VIVE Super NPK + wetting agent VIVE Wet and last option 5, it was fertilizer VIVE Ligno Super + wetting agent VIVE Wet. These variants were applied in the same terms and 28 days and 14 days before flowering. Then again 14 and 28 days after flowering. Comparison of all variants were performed on the base uvology and analytical values. Of uvology values measured weight of grapes from one bush, the weight of one grape, berry weight and 50 berries, and then even the weight of stem. The main indicators were selected analytical sugar content, acidity pH and assimilable nitrogen. Further analyzes were also performed sheets after the application of fertilizers. Results showed differences in nutrient content in the dry leaves between experimental and control variants fertilized variant. The best results in terms of nutrition were achieved in variants which used fertilizer VIVE Ligno Super Series. Compared with the control variant significantly increased the contents of macronutrients (+43,1%), secondary nutrients (78.4%) and micronutrients (+38.8%). It was demonstrated that the use of fertilizers to increase the yield of grapevine and reduced acidity. Achieving higher sugar after application of fertilizer series VIVE in this work confirmed, however, the yield increased. Preparations had a significant influence on the content of assimilable nitrogen, which is very important during fermentation must. Health status of grapes was good, which appeared in the analytical evaluation of pH, which is for all variants ranged from 3.16 to 3.21, but due to bad weather development was necessary to harvest crops early.
