not exceed the annual average of 20 mm. Groundwater is the
main source for both drinking and irrigation systems.
Environmental stresses like high summer temperature,
salinity, drought, low soil fertility, and wind are the major
challenges that Libyan farmers face (Zurqani et al. 2019).
Nevertheless, this large area of land was placed into cultivation, and different legumes and cereal crops are cultivated
in the oases. Cowpea is one of the earliest legume crops
known to the inhabitants of Fezzan. It has gained a wide
popularity between farmers in many oases because it is used
mainly as a source of food. Although Libyan flora is rich in
leguminous plants and occupies the third position among
other families, studies related to the description and characterization of symbiotic rhizobia with these plants are still
limited and have been limited to some cultivated crops and
woody legumes (Mohamed et al. 2000; El Sadi 2004), as
well as some types of wild clover (Medicago spp.)
(Mohamed 2018).
Many Libyan wild plants are threatened with extinction
due to drought, salinity, and overgrazing (Zurqani et al.
2018). That is why the interest in these plants in terms of
preserving their seeds and their propagation was urgent and
received some attention from those interested in agriculture
and the environment. However, research on endemic rhizobia that is compatible with these plants has not been provided with adequate attention, and information about their
physiological properties and their symbiotic features is still
limited. The most important goals that researchers sought in
their studies and research include: searching for symbiotic
rhizobia with some wild leguminous plants that are abundant
in arid and semi-arid lands from Libya; testing the ability of
isolates to symbiosis and nitrogen fixation with cultivated
