Effect of Organic Fertilization and Mycorrhization on the Growth and Yield of Artemisia annua L. Plants in Soil Fortified with Exogenous Nitrogen

The production of Artemisia annua, as well as that of other cultivated plants, is influenced by environmental factors which disrupt all vital functions. Therefore, finding a healthy production method remains a major challenge in meeting the demand for these plants. The aim of this study is therefore to evaluate the influence of organic fertilization on the growth of A. annua plants, with the aim of meeting demand in a sustainable manner. To achieve this, 1.5-month-old Artemisia annua plants are transplanted into fields in an experimental design consisting of two blocks separated by 1 m. The first block is fertilized with AMF and the second with ENTO, with three repetitions in each block; Both are irrigated with purified water rich in minerals, mainly the two forms of nitrogen that can be absorbed by plants: NO 3 − (79.65 ± 07.6) mg/l, NH4+ (1250 ± 121.3) (mg/l) with a pH of 7.4 ± 0.3. The mineral elements in the leaves and the agronomic and biochemical parameters are evaluated. The results show that fertilization with AMF and ENTO, followed by irrigation with purified water, increases the mineral absorption of A. annua, except for sodium in acidic soil. A significant negative correlation (p < 0.05, r = −0.57) was observed between proteins and chlorophylls, between proteins and flavonoids (r = −0.45), as well as between flavonoids and phenols. This would be an appropriate biological fertilization method for improving Artemisia production, as it is a valuable crop.
