Abdullah, M. A., H. Al- Yasee, Y. Al- Sudani and M. M. Khandaker, 2017. Developing weeds of agricultural crops at different levels of heights, in taif area of Saudia Arabia. Bulg. J. Agric. Sci., 23 (5): 762–769

This study continued during the eighteen months of 2015-2016 to identify the flora weeds within the agricultural fields at the three levels of height (Area A = 1700 m, Area B = 2200 m, Area C = 2000 m from sea level) in Taif agricultural area of Saudi Arabia. The results showed the presence of high density of weeds which belong to 23 families. Where it was most presence of the family Amaranthaceae, as well as the study shows a prevalence of approximately 10 families in three different areas: Amaranthacea, Asteraceae, Boraginaceae, Cyperaceae, Poaceae, Convolvulaceae, Chenopodiaceae, Malvaceae, Papaveraceae, and Solanaceae.  The results also showed the presence of high density of some of the herbs in the study areas such as: Amaranthus viridis, Amarnnthus hybridus, Centure sp., Sonchus oleraceus, Convolvulus arvensis, Cyperus rotundus, Malva parviflora, Argemana Mexicana, Solanum incanum. This study has great significant value to suggesting suitable weed control method and further investigations of weeds ecology at different level of height in Taif Area of Saudi Arabia.
