Other claims from this paper (4)
- Intervention effect Phosphorus did not significantly affect cowpea nodule formation.
- Intervention effect Potash did not significantly affect cowpea nodule formation.
- Observation Native rhizobia produced abundant effective nodules on cowpea without applied nitrogen despite leached, acidic soils.
- Observation The authors infer that native rhizobia are adapted to local soil conditions.
