Cotton is a widely
cultivated fiber crop and plays an important role in the globe. In Ethiopia,
cotton is produced in small and large scale, but commercial farms are greatly
affected by the problem of weed infestations. Weed survey was done in the
potential irrigated cotton growing areas of Middle Awash at seedling and
flower initiation stages of the crop. From all locations, the specimen was collected and tagged. Identification of the specimen in
the field was done based on weed identification guidelines and those
specimens difficult to identify in the field were identified by the national
herbarium of Addis Ababa University. Frequency, Abundance, Dominance and
Similarity Index were done according to their formula. A total of 27 weed
species from 17 families were recorded from all locations. The most dominant
weed species are from Poaceae, Amaranthaceae, Euphorbiaceous, Malvacea,
Convolvulaceae and Asteraceae weed families in all locations. Weed species
composition are different among crop growth stage and similar between
districts and across districts and hence, a similar management practice will
be applied for the districts.
