The experiment was carried out during the growing season of 2021 in the Sheikhan area,70 km east of Mosul city, near the Koml River, The experiment included two factors, the firstfactor was height cutting level of the Giant reed plant (at the soil surface, 5, 10, 15, 20 cm),and the second factor was the frequency of cutting (once, twice, three times), The experimentwas implemented according to the factorial experiments system, using a CompletelyRandomized Design with three replications, The results showed that, the height of the giantreed plant, leaf width, leaf length, leaf area and shoot system dry weight reduced by increasingcutting number up to three times compared to one cutting by (56.2, 19.3, 34.9, 45.8 and 53.8%).While the stem diameter was not affected by the frequency of the cutting process. In addition,stem height, stems diameter, leaf length and dry weight were decreased by lowers cutting levelcompared with the control, while leaf width and leaf area were not affected by cutting height,The overlap of the cutting levels with the frequency of the cut three times had a clear effect onthe studied characteristics.
