The effect of biological and chemical fertilizers on chlorophyll and artemisinin content in Artemisia annua L.

In order to consider impact of biological and chemical fertilizers (N, P) on chlorophyll and rut emisinin content which exist in Artemisia annua L. an experiment was carried out in factorial design in completely randomized design with 4 replications in Zabol University in 2011. Treatments included chemical fertilizers (N, P) in 4 levels (NOPO, N40P40, N80P40, N80P80) and biological fett ilizers in 4 levels (Control, Nitroxin [include bacteria which stimulus growth (Azotobacter and Azospirillum)], Bio-phosphoms [include bacteria which stimulus growth (Bacillus and Pseudomonas)] and Vennicompost fettilizer. Applying biological fett ilizers lead to enhance active ingredient mtemisinin in Artemisia annua L. and among biological fett ilizers, Vennicompost has the most effect on enhancing mtemisinin. The most increase in attemisinin content refers to Vennicompost + N80+P80 with (0.334%). Overall results of this experiment showed that the ability of Azotobacter and Azospirillum in stability N and capability of Bacillus and Pseudomonas in dissolution insoluble phosphates, enhanced mtemisinin effectively. About chlorophyll concentration, applying biological fettilizers specially vennicompost has better impact that chemical fett ilizers and Vennicompost + N80P80 had better impact on chlorophyll content in compm·ison with other experimental treatments
