The effect of different treatments of mineral nutrition upon the variation of fruitfulness of buds of Italian Riesling grapevine cultivar has been studied. The results of the study of the coefficient of fruitfulness, percentage of developing and fruitful buds with certainty have shown that all the treatments of mineral nutrition applied had a favourable effect on the fruitfulness of buds, but that there were differences between treatments. The least favourable effect had the variants with the prominent insufficiency or surplus of some elements. The highest favourable effect had the variants with average contents of nitrogen and phosphorus and higher contents of potassium.
