| Abstract The study was conducted at orchard of Agriculture Research Center/Ainkawa / Erbil north of Iraqduring twogrowing seasons 2013 and 2014 on grape currant (Vitis vinifera L.) Thompson Seedless cultivars were trained of Alghemriaat and spur pruning let (8) cane is fixed number and let them (6, 8 and 10 bud or eye / cane), of add humic acid concentration are (zero, 4.5 and 9 g/vine) and Gibberellic acid spraying were done (zero, 50 mg / L), effect on growth vegetative (sprouting %, leaf area and leaves area / vine ) and chlorophyll content. Using of randomized complete block design (RCBD). The levels of pruning 6 and 8 eye / cane caused significant increase in bunch weight (278,72 and 280,50 g / bunch), total yield (16,15 and 18,71 kg / vine) of vine and Mineral content (N (1,17% ), k (0,72% and 1,22%)) in berries. added 9 g humic acid / L led significant increase in bunch weight (278,94 and 273,72 g / bunch), total yield (18,07 and 19,18 kg / vine) of vine andMineral content (N , k) in berries. also reached the same results when gibbereliic acid spraying. Interaction between of pruning 8 eye / cane + 9 g humic acid / L + 50 mg GA3 / L gave the best results for thebunch weight (310,66 and 339 g / bunch), total yield (21,01 and 23,16 kg / vine) of vine and Mineral content (N (1,30% and 1,08%), k) in berries the for both seasons. | ||
