- Intervention effect Nodule dry weight, specific C2H2 reduction and shoot P concentration responded before growth.
- Intervention effect Nodule P concentration responded only slightly to P addition.
- Intervention effect P supply raised nodule dry weight faster than shoot dry weight.
- Intervention effect P supply raised specific C2H2 reduction faster than shoot dry weight.
- Intervention effect P supply raised shoot P concentration faster than nodule P concentration.
- Intervention effect Combined N increased shoot dry weight only at highest P levels.
- Mechanism Reduced nodulation and fixation under P deficiency were attributed to impaired shoot metabolism.
