Artemisinin yield in stem was found to be increased with plant’s developmental stages and reached to its maximum at pre- flowering stage irrespective of treatment over control. The yield values ranges from 3.28 to 4.20 kg ha−1; the highest yield was found in treatment T4 followed by T3 and T2 by 28.05, 17.07 and 7.31% over control, respectively at pre-flowering stage (Table 9).
