Qualitative and quantitative determination of weed occurrence in wheat in West Shewa Zone of Ethiopia - Addis Ababa (Ethiopia) CIMMYT : 1999 - Printed
Qualitative and quantitative determinations of weeds in wheat fields were conducted in West Shewa Zone during the 1995-1997 cropping seasons. The abundance, frequency, dominance, and species composition of weeds occurring in wheat in major growing areas were determined. The most frequent, abundant, and dominant weed species were Polygonum nepalense, Guizotia scabra, Galinsoga parviflora, Corrigiola capensis, Plantago lanceolata and Digitaria spp. The average values for frequency and dominance of weeds in wheat ranged between 0.4 to 79.1% and 0.01 to 20.70%, respectively. Similarity indices of weed communities in different locations were also determined to be > 60% across all locations sampled. Specific weed problems and farmers' practices to control weeds are described.
