Abstract
This investigation was carried out aiming to study the effect of cattle manure (CM) rates (15, 30 and 45m3/fed.) alone or and different levels of active dry yeast, ascorbic acid and actosol on growth, yield, essential oil production and chemical composition of Artemisia abrotanum, L. plants. The results showed that cattle manure at rate of 30 m3/fed, in both seasons, gave the highest values of the tallest plants; number of branches per plant; plant fresh and dry weights, herb fresh and dry yields /fed., essential oil percentage, essential oil yield in fresh herb per plant and total carbohydrates %DW in herb total phenolic content, antioxidant activity, pigments, and mineral elements, compared to other cattle manure rates. Bio-stimulant ”ascorbic acid” at 100 ppm had significantly increased the number of branches per plant, plant fresh and dry weights, herb fresh and dry yield /fed.,essential oil percentage, essential oil yield in fresh herb and chemical composition compared to other bio-stimulants. while the highest values for plant height were obtained from plants fertilized with actosol in the first cut in both seasons. Interaction between cattle manure at rate of 30 m3/fed. and bio-stimulantof ascorbic acid at 100 ppm had a significant effect on vegetative growth characteristics as gave the highest values in both cuts of the two seasons .it herb fresh and dry weights/plant, herb fresh and dry yield/fed., essential oil yield (ml/plant), essential oil yield /fed. and total carbohydrates %DW in herb total phenolic content, antioxidant activity., K in dry herb and N % in herb. carotenoids contents ”gave the highest value in second cut of both seasons
