ABSTRACT

The propagation of Artemisia annua is hindered by shortage of seeds, germination problem and effective protocol. Field experiments were conducted during both rainy and dry seasons to determine the effect of levels of organic and inorganic manure on the vegetative growth of A. annua. Results of Analysis of Variance (ANOVA) indicated no significant difference between the seasons with respect to the parameters studied excerpt the canopy spread and leaf fresh weight before flowering (P?0.05). Similarly, no significant difference was observed during the irrigation trial except in 25 kg/ha NPK on the canopy spread, 50 kg NPK on whole fresh weight after flowering and 4 tone/ha poultry fertilizer on leaf fresh weight after flowering. However, a significant difference was observed under the rainy season experiment except in whole fresh weight before flowering, leaf dry weight before flowering and leaf dry weight after flowering. Application of 6 t/ha of poultry manure during the raining season had the highest plant height followed by 4 t/ha of poultry manure during the irrigation trial. Similarly, rainy season trial had the highest number of branches in 50 kg/ha of NPK. Rain trial had the best leaf fresh weight after flowering at 6 t/ha of poultry manure and the best leaf dry weight before flowering was observed at 25 kg/ha of NPK during the rain trial.
