Other claims from this paper (10)
- Intervention effect P fertilizer addition increased the number of root nodules and seed yields of Phaseolus vulgaris.
- Observation Nodulation and seed yields varied enormously between sites, even where fertilizers were applied.
- Intervention effect Adding 26 kg P ha-1 increased the amount of N2 fixed to 8-16 kg N ha-1.
- Intervention effect Adding 26 kg P ha-1 increased the share of N derived from N2 fixation to 48-51%.
- Intervention effect Rhizobium inoculation with P addition increased nodulation and N2 fixation marginally above P alone.
- Intervention effect Inoculation with P more than trebled the number of nodules at Kilacha.
- Intervention effect Inoculation with P only marginally increased total N accumulation at Kilacha.
- Intervention effect Addition of N fertilizer (45 kg N ha-1) increased yields slightly above P alone across all sites.
- Intervention effect Addition of P or N fertilizers only marginally improved seed yields at two Kilimanjaro/Meru sites.
- Recommendation Further assessments of nodulation and N2 fixation under farmers field soil fertility conditions are needed.
