3.3. Effect of organic manure and chemical fertilizers on artemisinin content
Artemisinin content was estimated in leaf, stem and inflorescence. Maximum artemisinin content was observed in leaf (0.70%) followed by young inflorescence (0.61%), mature inflorescence (0.20%) and stem (0.05%). Artemisinin content in leaf has been observed to be increase progressively irrespective of treatments over control and reached to its maximum at pre-flowering stage (0.55–0.70%). The maximum increase in artemisinin content was recorded in T4 (26.99%) followed by T3 (18.11%) and T2 (6.15%) over control, at pre-flowering stage (Table 5).
