A comparative study of different pruning ways and bud load, as well as their influence on growth, yield and quality of Rhine Riesling B-21, Riesling Italian, and Zupljanka vine cultivars in the conditions of the Rasina vine district, during the period 2000 - 2001, is given in this paper. This research results have shown that grape yield and quality varied, and the greatest grape yield was observed in the variant with the greatest bud load. The Rhine Riesling B-21 demonstrated the best results.

In the period from 1994-1996 under conditions of Orahovac vineyard district in Kosovo and Metohija, the agrobiological properties of variety Riesling Italian were investigated in different training systems. The results of investigation indicate that examined training systems, bud load and way of pruning exhibited a significant influence on growing fertility, yield and grape quality of this variety.
