The objective of this study was to assess the effect of bud load and the green foliage they produce on the yield and quality of grapes and wine the cultivar Liza. Three levels of bud loading, i.e., canopy density, were applied. The first variant of bud loading was 2 bud spurs and a cane with 12 buds, or 11.7 shoots per meter of canopy length. The second variant of bud loading was two canes each with 12 buds, or 20 shoots per meter of canopy length. The third variant of bud loading was two canes each with 17 buds, or 28 shoots per meter of canopy length. Influence of meteorological parameters on these cultivar features was alo monitored. Ripening dynamics and grape and wine quality were observed through the test years. Based on the long-term investigations and the results of this study, it was concluded that the increased bud load and canopy, with the applied small plant distances in the row, decreased the (potential) bud fertility, grape yield, and grape and wine quality.
