| Abstract | ||||
| This study was conducted through two consecutive seasons (2019 and 2020) seasons at a private vineyard at El-Khatatba region, Minufyia Governorate. The chosen vines were 7-years old, grown in a sandy soil, spaced at 2 X 3 meters, irrigated by the drip irrigation system, trellised by gable supporting system. Vines were trained to quadrilateral cordon and spur-pruned. Three different levels of pruning were used, namely (48 & 60 &72 nodes vine) under three different lengths of the nodes (2-3-4 nodes) with different number of fruiting spurs.Results show that the vines were pruning at levels 24 spurs×2 nodes (48 nodes /vine) gave the highest significant values of busted buds and bud fertility percentages, shoot length, number of leaves, leaf surface area, total chlorophyll in leave Nitrogen, the content of phosphorous, potassium and magnesium in leave, as well as improved physical characteristics of clusters and berries, TSS, % and TSS/acid ratio, while decreased total acidity in berries. On the other hand, the vines were pruning at levels 18 spurs/4 nodes (72 nodes / vine) gave the highest significant values of yield per vine. | ||||
