Other claims from this paper (7)
- Intervention effect The 50-25% mineral-N regime significantly increased nodulation, biological N fixation and fresh-pod yield of hydroponic common bean compared with the other reduced inorganic-N treatment.
- Intervention effect The 75-25% mineral-N regime applied in the vegetative stage restricted nodulation and biological N fixation in common bean.
- Intervention effect The 75-25% mineral-N regime applied in the vegetative stage caused significant yield losses in common bean.
- Intervention effect Both rhizobia strains stimulated nodulation and biological N fixation in common bean relative to the no-inoculation control.
- Association The biological N fixation capacity facilitated by the rhizobia strains was suppressed as inorganic-N input increased.
- Intervention effect Common bean plants given the 50-25% N regime and inoculated with PVTN21 showed an 11% yield loss compared with plants given 100% N.
- Mechanism The authors conclude that N-use efficiency optimises biological N fixation and reduces dependency on mineral N input.
