[Effects of zinc manganese and boron on artemisinin and yields of Artemisia annua].
OBJECTIVE
To explore the effects of micro-elements fertilizers on the quality and yields of Artemisia annua.


METHODS
Field experiments were conducted according to the method of random blocks design. After the harvest the yield was calculated and the content of artemisinin was determined.


RESULTS
By applying 0.1%-0.5% Mn and 0.1%-0.5% Zn the dried leaf output and artemisinin content were increased.


CONCLUSIONS
The suitable ranges of Mn and Zn can increased the yield and artemisinin content of A. annua.
