Abstract

The study was carried out in the wooden canopy of the Department of Horticulture and Garden Engineering/ college of Agriculture/ Anbar University the season of 2018 to study the effect of some nutrients on the activation of the growth grape varieties of Halawani and Black Hamburg, where the following nutrients were used: Humic acid and amino acids (0, 1.5 and 3m.L -1) Algae extract (0, 1.5 and 3 g.L-1) by using the random complete block design were sprayed as of 15/5/2018 and repeated every twenty days with four sprinkles. The study showed an increase in the properties of leaf area for sapling, branches number, chlorophyll content, the percentage of dray matter in leaves and percentage or ripened wood and total wood when Algae extract treatment 1.5 g.l-1 to (284.79 dcm2, 3.33branch .Sapling-1, 41.89 mg.g-1 fresh weight, 46.58% and 84.93%), respectively, While it decreased in control to (109.60 dcm2, 2.08 branch .Sapling-1, 33.58 mg.g-1 fresh weight,38.52% and 46.44%), respectively. The percentage of dray matter in branches when Algae extract used 3 g.l-1 increased to 46.52% while its decreased in counted to 39.65%.
