This study aims to improve the productivity of Artemisia annua L. based on natural fertilizer in Adamawa-Cameroon. Field experimentations were carried out during two cropping years (2023 and 2024). A randomized complete block experimental design with 12 treatments (unfertilized plots (C-), chemical fertilizer (C+), cow dung manure-based compost (CCD),  poultry litter-based compost  (CPL), vivianite (V), pyroclastite (P), cow dung manure-based compost + vivianite (CCDV), cow dung manure-based compost + pyroclastite (CCDP),  poultry litter  based-compost + vivianite powder (CPLV), poultry litter-based compost  + pyroclastites (CPLP), cow dung manure-based compost + vivianite powder + pyroclastite (CCDVP)) and 03 replications were used. Physico-chemical characteristics of growth substrates (soil and composts), and growth parameters were evaluated. Results show that the soil of Bini-Dang is acidic and poor in mineral elements necessary for Artemisia better growth. Artemisia growth varies significantly (p<0.05) depending on fertilization and experimentation year. Overall, unfertilized plants exhibited significantly (p<0.05) the smallest growth parameters. CCDV fertilizer increased fresh biomass at 528.33% compared to C- and at 258.23% compared to C+ respectively in 2023 first cropping year. However, CPLV fertilizer increased fresh biomass at 431.65% compared to C- and at 414.33% compared to C+ in 2024 second cropping year. The supply of the following combination, 1 Kg compost derived cow dung manure + 10 g pyroclastite powder, or 1 Kg compost derived poultry litter + 10 g vivianite powder was found to be very promising in improving the sustainable Artemisia production.
