A weed survey was carried out in seven islands in Dongla area during the summer season of 2004 to determine the most common and prevalent weed species associated with maize (Zea mays L.) cultivation. A stratified random sampling procedure was adopted, whereby each island was divided into fields of which 10 were randomly selected. Number of individual weed species was determined in 10 quadrates each 1 square m. The field density, frequency, uniformity and relative abundance of the species were determined. Data revealed the presence of 25 species of annual and perennial plants belonging to 13 families. The highest number of species occurred in Elmasakeen whilst the lowest was recorded in Artigasha. C. dactylon, C. rotundus and P. oleracea were weeds that occurred at high relative abundance. Species with moderate relative abundance included S. arundinaceum, A. viridis, E. colona and G. gynandra. The other species occurred in 1 -2 islands and exhibited low to very low relative abundance
