The paper has to find out which factory preparation, among the existing, having different concentration of macro and micro elements will give the best results regarding the potassium content in a leaf of the grape vine variety Vranac which is a dominant variety for the production of red wines in Montenegro (Yugoslavia). Among any of the 9 variants there is no significant difference of potassium content in a leaf before flowering and in the phase of physiological maturity of grape. After flowering such difference occurs among some variants. The potassium content in a leaf of the variety Vranac in the existing agroecological conditions is considerably under the expected optimum, but it is not vegetatively reflected on the productivity.
