The intense heat, high solar radiation, limited water resources, and poor soil conditions in the Sistan region have weakened Yaghouti grapevines. Achieving optimal quantitative and qualitative yields requires precise management of bud numbers during winter pruning and regulation of vegetative growth throughout the growing season until harvest. This study evaluated four levels of winter balanced pruning intensity and four levels of green pruning intensity. The winter pruning treatments included:
Control (local practice) Light pruning (10+60) Moderate pruning (10+40) Heavy pruning (10+20)
The green pruning treatments included:
Control (local practice) Light pruning (pruning green shoots, eight nodes above the last cluster) Moderate pruning (removal of lateral shoots + pruning green shoots, eight nodes above the last cluster) Heavy pruning (removal of non-productive green shoots from the previous year's fruiting branches + removal of lateral shoots + pruning green shoots, eight nodes above the last cluster)
Heavy winter pruning increased total soluble solids (8.4%), total acidity (14.5%), juice content (5%), cluster sunburn (11%), and flavor index (7.6%) compared to the control. It also decreased acidity (20.1%) and reduced the number of days to maturity (10.5%). Overall, the highest flavor index for Yaghouti grapes was observed under heavy winter pruning combined with the removal of non-productive green shoots from the previous year's fruiting branches, complete removal of lateral shoots, and pruning of green shoots, eight nodes above the last cluster.
