Study the effect of biological and chemical fertilizers on Artemisia annua L. quantitative characteristics after and before flowering

Artemisia annua L. is one of the important herbal plants, which is applicable for some disease treatment such as, Cancer and Malaria. To consider the effect of biological and chemical fertilizers on Artemisia annua L. quantitative characteristics an experiment was carried out in factorial design in completely randomized design with 4 replications in a educational green house in Tehran. Treatments included chemical fertilizers (Nitrogen (N), Phosphorus (P)) in 4 levels (N0P0, N40P40, N80P40, N80P80) and biological fertilizers in 4 levels (control, Nitroxin, Bio-phosphorus and Vemricompost fertilizer. Results showed that using biological fertilizer, and increasing different levels of chemical fertilizers (N, P) had significant effect on under consideration characteristics. Means comparison showed that biological fertilizers application leads to significant increase in all under consideration features. Among biological fertilizer, Vemricompost treatments the most effective. Means comparison of applying different levels of chemical fertilizers indicated that N80P80 had the most increase in features. Interaction effect had different effects on those features.
