Papric Dj. | Kuljancic I.
In field conditions and two locations of viticultural region of Fruska Gora (Yugoslavia), were performed foliar analysis and investigated the grape yield of Riesling Italian and Riesling White cultivars. Nitrogen and potassium content was higher in leaves of Riesling Italian, but the better accumulation of phosphorus was in Riesling White cultivar. In both locations was noticed very expressive deficiency of potassium. The grape yield is higher in Riesling Italian cultivar. The average grape yield is under potential of examined cultivars because of common deficiency of potassium and not favorable relation between nitrogen and potassium.
