We also assessed whether these weeds were directly or indirectly beneficial for humans. Results of this study revealed a total of 33 species belonging to 20 different families which were collected and identified. Weeds were arranged in alphabetical order according to their respective families. Data inventory constitutes family name, botanical name, local name and life form. Results revealed the relative diversity of each family as Poaceae at 18.18% and Asteraceae at 15.15%. Out of 33 weed species, 64% were annual, 30% perennial and 6% biennial. The soil of the studied area was a hard, silty loam texture, with a slightly alkaline pH and low electrical conductivity.
