| Abstract | ||
| This study was conducted in the grape orchard of Agricultural Research Center-Ainkawa - Erbil. The similar grapevines were selected in growth force, which were brought up in a lunar way and were planted on lines (2m between the vines and 4m between the lines) and from north to south. To study the effect of three levels of pruning (let 8 canes. vine-1) the first level 6 eyes. cane-1, second level 8 eyes. cane-1 and third level 10 eyes. cane-1, of add humic acid in three concentrations (0, 4.5 and 9 g.vine-1), and spraying with Gibberellic acid with two concentrations (0 and 50 mg.l-1) in the mineral content of the leaves and berries of seedless Bea–Denk cultivar. Using the randomized complete block design (RCBD) with three replicates. The results showed that pruning level (let 8 eyes.cane-1) led to increase the nitrogin and pottasium percentage and iron content in leaves, however, increased the content of berries of iron and zinc, while reduced leaves content of zinc and the phosphorus percentage. While, concerning of the humic acid the results showed that 9 g.vine-1 humic acids caused to increase the nitrogen, phosphorus and potassium percentage in the leaves compared to the comparison treatment, so that reduced the zinc content of the leaves. On other hand, the spraying with 50 mg.l-1 of Gibberellic acid led to non-significant increase in all the studied elements in the leaves and berries with the exception of the amount of zinc in the berries. | ||
