Abstract

The current study was conducted during the 2019–2020 growing season in Dhi-Qar University's Alsaran Canopy. Nano fertilizer was used to test the effects of adding Nano- 1 macro elements NPK at three concentrations (0, 30,60) mg l-1 on some growth characteristics of Myrtle plant, Myrtus communis, Three replicates of the experiment were used in the RCBD design. Important Difference Test at 0.05 probability. Results appear that The Nano fertilizer is 60mg l-1 significantly increased the average plant height, stem diameter, leaf area, chlorophyll and carbohydrates leaf content, and percentage of oil, fresh weight. The concentration of humic acid Significantly increasing plant height, branch count, stem diameter, chlorophyll content, carbohydrates, and the highest percentage of oil. It recorded an average of (87.44 cm, 12.13 mm, 10.56 branches). 2, 105.44 mg.100 g fresh weight, 82.00 g. dry matter and 0.51%, respectively, while H1 treatment excelled with the largest leaf surface area of8.79 cm2.The interaction treatment H2N1 was superior to the control treatment H0N0 and the rest of the treatments in the study regarding plant height, stem diameter and leaf area, while H2N2 was superior in fruit content of chlorophyll and carbohydrates.
