Other claims from this paper (12)
- Observation Cowpea had its highest nodule fresh weight, 4.63 g plant−1, in soil from Isiolo.
- Observation Green gram had its highest nodule fresh weight, 3.32 g plant−1, in soil from Kilifi.
- Observation Cowpea had its lowest nodule fresh weight, 2.17 g plant−1, in soil from Bungoma.
- Observation Green gram had its lowest nodule fresh weight, 0.72 g plant−1, in soil from Bungoma.
- Observation Cowpea symbiotic nitrogen fixation was highest in Kilifi soil at 98%.
- Observation Green gram symbiotic nitrogen fixation was highest in Kilifi soil at 97%.
- Intervention effect Commercial rhizobial inoculation did not significantly affect green gram nodulation, biomass yield, or shoot nitrogen content compared with controls.
- Observation Nodule IGS analysis revealed six groups, and only group IV matched commercial inoculants.
- Observation IGS group III dominated cowpea nodules under Biofix, Rizoliq, and no inoculation, at 63.2%, 60%, and 52.9%, respectively.
- Observation IGS group III dominated green gram nodules under Biofix 704, Rizoliq, and no inoculation, at 75%, 73.7%, and 61.1%, respectively.
- Recommendation Routine inoculation with current commercial inoculants was judged unnecessary for improving biomass yields of cowpea and green gram in these Kenyan regions.
- Recommendation The authors recommended using indigenous rhizobial strains that perform well with cowpea and green gram.
