e1“Cowpea [ Vigna unguiculata (L.) Walp]”
e3“Native rhizobia were isolated from root nodules of cowpea plants used as trap cultures”
e4“Additionally, 50% of the isolates recorded SE of >80%, while 35.7 and 14.3% of the isolates had SE of 51–80 and <50%, respectively”
e5“The isolates were further assessed for symbiotic efficiency (SE) in the greenhouse and field experiments”

Other claims from this paper (9)
- Intervention effect Native rhizobia isolates significantly increased cowpea nodule number and nodule dry weight in the greenhouse compared with the uninoculated control.
- Intervention effect Native rhizobia isolates significantly increased cowpea shoot and root dry weight in the greenhouse compared with the uninoculated control.
- Observation Half of the native isolates (50%) had symbiotic efficiency above 80%.
- Intervention effect Rhizobia inoculation significantly increased cowpea nodulation and shoot dry weight in the field compared with uninoculated controls.
- Intervention effect Inoculation with native isolates increased yield by 22.7% over the uninoculated control in the first season.
- Intervention effect Inoculation with native isolates increased yield by 28.6% over the uninoculated control in the second season.
- Association The rhizobia inoculants showed no preference for any cowpea genotype.
- Association Cowpea performance of the inoculants was influenced by season and study location.
- Recommendation The native isolates have potential to be developed into a low-cost biofertilizer for sustainable cowpea production.
