| Abstract | ||
| This study was carried out in the Malta nursery - Dohuk forests and rangelands directorate - Dohuk city, from 15th Mar 2015 to 1st July 2016 to investigate the effect of Irrigation level (100, 80, 60) % and Fe concentrations (0, 75 and 150) mg.L-1 on the growth and essential oil percentage of lavender plant Lavendula angustifolia Mil. The results were show that: decreasing the Irrigation level (increased water stress) gave significantly decreasing in the plant high, Plant growth index, Vegetative dry weight and number of inflorescence and significantly increased in the Volatile oil percentage. While increased the concentration of the Iron to 75 mg.l-1 gave significantly increased in plant high, Plant growth index, whereas spraying Fe at a concentration of 150 mg.l-1 caused a significantly increased in branches number, Vegetative dry weight, length of flower stem, number of inflorescence and Volatile oil percentage. The interaction between the factors significantly affected on all studied parameters. | ||
