Kemal Kitaba, Rameto Nura, Ejigu Ejara, Dejene Legesse

The assessment of weed flora was conducted at two zones of southern Oromia in 2020-2022 production years. From each zones the districts were selected purposively based on potential of crop they produce. Identification of the major crop weeds that causes huge damage on production in proper way for a given situation is essential for collecting further information about the weeds pests as well as for developing necessary management measures. on the other hand, wrong identification of the target species of weed in the native habitat may lead to the introduction of the wrong management options, which may also fail reduce the pests. The result showed a total of about 19 weed species under 8 families in common bean, 21 species of weed under 8 families in maize, and twenty-one weed species under seven families were identified in Teff fields. Weed families identified from the surveyed areas includes Asteraceae, Commelinaceae, Compositeae, Cyperaceae, Papaveraceae, Poaceace and Solanaceae. Among the identified weed species Asteraceae and Poaceace were the most dominant weed families when compare to the other families of weeds. Consequently, weed species composition varied among each district. However, in some districts there is alike similar index, in such districts the management options applied should be analogous. In general, among the identified weed species, broadleaf and grass species have greater proportions.
