Weed diversity around Manihot esculenta, Zea mays and Cucumis sativus in four villages (Alakahia, Choba, Ozuoba and Rumuosi) within Obio/Akpor L.G.A. was studied to determine the species of weeds common to them. Parameters such as frequency, density, relative abundance and species evenness were used to determine the species diversity as well as the important value index. Analysis of variance was calculated for all. Result showed that Ageratum conyzoides L. had the highest frequency (87.5%) and importance value index (98.4) among all weeds found around M. esculenta while Rottboellia conchinensis and M. alternifolius had the highest density (5.69 kg/m3) and relative abundance (8.10) respectively. In Zea mays farm, Cyperus esculentus L. was the most frequently seen (81.2%) and the most densely populated (6.06 kg/m3) while M. invisa recorded the highest relative abundance (12.24). Four weed species had the same highest frequency of 75% in C. sativus farm among which S. monostachyus had the highest density of 7.19 kg/m3 recorded in this study. The highest importance value index of 96.9 was recorded in C. esculentus at the Zea mays farm. Out of the 26 species present in all the locations, A conyzoides and S monostachys were present in all the sites The outcome of this study will enable agronomists to know the kind of weeds to expect around these crops when cultivating in the Obio/Akpor L.G.A. This will form the basis in the control and management of weeds including the measures and practices to adopt.
