Diversity and Distribution of Cereal Weed Species in Highland of Guji, Southern Ethiopia

A weed survey was carried out during the primary cropping seasons of two consecutive years in the Highland of Guji zone, Southern Oromia, to assess the distribution and relevance of weeds in cereal crops and to investigate the most common weed flora in cereal crops. Three agro-ecologically representative districts provided the data for this survey. In total, 180 fields were evaluated during this study from four kebele chosen from each area. Quantitative and descriptive approaches were used to test the collected data. The result was the identification of 42 different weed species from 18 different plant groups. The survey revealed that the families with the highest number were Rubiaceae, Polygonaceae, Compositae, and Gramineae. Galansoga Palviflora, Guizotia Scabra, Tagetes minuta L, Snowden Polistachia, Avena fatua, Bromus pectinatus Thunb, Phalaris paradoxa L, Setaria pumila, Digitaria abyssinica, Bidens pilosa L, Bidense pachloma, Parthinium hystrophorus L., Polygonum Nepalense, Oxygonum sinuatum, Rumex abyssinica, Andropogon Abyssinicus, Lauracaea Cornuta, Galium Sporium were the most prevalent species were Galansoga Palviflora (Hochst. Ex A. Rich) Stapf (68%) and Snowden Polistachia (51%). Furthermore, Galansoga Palviflora was regarded as the worst weed by the majority of farmers (90%) in high land districts, whereas Snowden Polistachia was listed as an important weed. These two weeds were also discovered to be the most prevalent, frequent, and abundant weed species in the highland agro-ecologies of the Guji Zone, according to the data gathered. However, in both the Mid land and Low land agro-ecologies of the Guji Zone, Setaria Verticillata (L.) and Setaria Pumila were found to be the most common, frequent, and dominant weed species of cereal crops. In conclusion, this study would offer fundamental details about the prevalence of cereal crop weeds in highland agro ecologies in the Guji Zone, which might used as the basis for further weed research and weed management studies.
