| Abstract |
Artemisia annua L. (Asteraceae) is an essential annual plant, which is included in the Chinese Pharmacopoeia, and is characterized by the treatment of some diseases aerial parts contain aromatic volatile oils and non-volatile sesquiterpenes used in pharmacopoeia. This investigation was carried out in the Floriculture Farm of the Horticulture Department Faculty of Agriculture, Benha University during 2019and 2020 seasons to study effect of planting distances and applying fertilization on vegetative growth, chemical constituents and oil of Artemisia annua (L)plant. On the other hand the effects of water regimes vegetative growth, chemical constituents and oil of Artemisia annua (L)plant. Treatments on Results showed, in both cuts and seasons, the maximum values of vegetative growth and root parameters were recorded planting distances (40*40 cm) and F3(100% organic fertilizers). Besides, the interaction between planting distances and fertilizations treatments had a significant effect on chemical compositions especially planting distance( 40*40 cm) and F3 in the two cut and at both seasons. In general, the highest values of essential oil percentage in leaves were recorded by the combined treatment between planting distance( 40*40 cm) and F3. Gc-MS analysis of of Artemisia annua L. essential oil revealed the presence of 23 component which were identified and the major components were champhore, cis-sabinene hydrate, trans β-ocimene, artemisia ketone, borneol, tranc- caryophyllene, myrtenal and β- Selinene.Furthermore, the highest value of artemisinin percentage (1.4 %) was scored by (60*60 ) with F2. Besides, The treatment 70 % FC followed descendingly by 100 % FC gaved the maximum values of the growth, essential oil , artemisinin content and the chemical constituents of this plant in the two cuts in both seasons. Consequently, it is preferable applying the planting distance( 40*40 cm) and F3 for enhancing the growth, essential oil , artemisinin content and the chemical constituents of Artemisia annua L. plant.
