Abstract

The development of vine growing and wine production in the area of
Coastal Croatia is directed to the production of high quality ecologic wines. In these efforts the use of mineral fertilizers is very important. By rational use of mineral fertilizers we come closer to the programme of health food. Therefore we made fertilization experiments on the introduced cultivars of Emerald rizling and Rkaciteli with the aim of rational use of mineral fertilizers without
negative ecologic consequences. The usage of various quantities of mineral fertilizers, even very big quantities had no influence on the growth and quality of grapes, so it can be concluded that it is not necessary to use big quantities of mineral fertilizers to achieve high yield or high quality of grapes, so fertilization with mineral fertilizers should be reduced to the smallest possible quantity.

Keywords

grapevine fertilization; NPK; average yield per vine (kg); chemical analysis of must
