weeds of barley crop at District Beir Bullerjam, Soloq Region, Libya for two
seasons (2020 to 2021). The current study is based on field research where recorded
most weed the grown species by survey followed by using quadrats and finally
calculating the weed density and their frequency. samples from the fields of the
barley crop using a quadrat of size 1 m × 1 m randomly thrown at different points
in the fields. The plants were identified with the help of available literature and
through comparison with the already identified plant species. Data inventory has
been documented in the form of family, Botanical name, vernacular name and life
cycle. A total of 67 weed species belonging to 54 genera and 21 families of
angiosperms. The dominant families according to the number of species were
Asteraceae (14 species), Fabaceae (11 species), Poaceae (9 species), and
Brassicaceae (7 species). The most dominant life cycle was annuals having 57
followed by perennials having nine species and biennials represented by only
two species.The results further revealed that the highest density (43.48 mˉ²) and
(30.36 mˉ²) were recorded for Lolium rigidum and Melilotus indicus respectively,
while the highest frequency were recorded for Melilotus indicus and Eruca sativa
