Additionally, varying doses of nitrogen fertilization displayed no statistical effect on the number of branches of wormwood. In the experimental years, the number of branches differed from 51.3 to 60.8 branches/plant. In some similar studies, the number of branches in different wormwood ecotypes was between 13.0 and 82.8 branches/plant (Elhag et al., 1992; Mert, 1999).
