Abstract:
A weed survey was conducted in six locations in Khartoum area: Elfaki Hashim, Jaziret Wawisti, Jaziret Islang, El Jerafa, Jaziret Tuti and Soba during the winter season of 2015/2016 to determine the most common and prevalent weed species associated with faba bean (Vicia faba L.) crop cultivation and to determine which weed type is dominated in Khartoum State. The data revealed the presence of 20 species of annual and perennial weeds belonging to 13families. Of these species 14 were dicotyledonous, 6 were monocotyledonous. The Poaceae, Asteraceae, Solanaceae and Amaranthaceae made up 15%, 10%, 10% and 10% respectively, of the total number of species. The remaining weed species belonged to 9 other families. The results indicated that the weed flora of Khartoum State was dominated by broad leaved weeds. The highest number of species (12) occurred in Soba, followed by Faki Hashim (11) while the lowest (8) was recorded in El Jerafa. C. rotundus, C. dactylon, B. aruciformis, E. colona, and T. terrestris prevailed in all locations. C. rotundus, C. dactylon, B. aruciformis and E. colona, were weeds that occurred at high relative abundance. The species with moderate mean relative abundance were T. terrestris L., G. gynandra, P. oleraceae and S. dubium Fresen. The other species exhibited low mean relative abundance.
