Abstract: The present study was conducted to standardize the pruning technique in recently released grape hybrid H-516 for processing purpose. The grapevines trained on bower system of training were pruned at 2, 3, 4 and 5-bud level during last week of January. The maximum per cent fruitful buds were recorded at 2-bud level followed by 3, 4 and 5-bud pruning level. The significantly higher number of bunches per fruitful bud (2.23 at 4th node) were observed in pruning done at 4-bud level. The yield per vine was highest (15.2 kg yield per vine) in pruning treatments where 4-buds were retained. Bunch weight and size did not differ significantly with various pruning levels. Anthocyanin (52.24 mg/100g) and total soluble solids content (18.13%) was maximum whereas, acid content (0.53%) was minimum with 4-bud pruning treatment. Present study suggested that in grape hybrid H-516, at the time of pruning, 4-buds per cane should be retained for better yield and improved fruit quality.
