- Intervention effect Dry matter production rose with phosphorus in mashbean.
- Intervention effect Dry matter production rose with phosphorus in mungbean.
- Intervention effect Dry matter production rose with phosphorus in soybean.
- Observation At up to 25 kg P ha-1, soybean had more biomass than mashbean and mungbean.
- Mechanism Enhanced root growth mainly explained soybean biomass advantage under low P.
- Mechanism Leaf area expansion also mainly explained soybean biomass advantage under low P.
- Intervention effect Low phosphorus severely inhibited mashbean leaf area development.
- Intervention effect Without P, photosynthetic rate was extremely low at later growth stages.
- Association N accumulation correlated positively with acetylene reduction activity across species.
- Observation Soybean absorbed more P than the other species at low P.
- Association P absorbed correlated positively with soybean biomass production.
- Intervention effect At low P, P concentration fell across plant parts.
- Observation The low-P reduction in P concentration was pronounced in nodules.
- Observation Soybean was interpreted as more tolerant of suboptimal P than mashbean and mungbean.
- Mechanism Soybean tolerance was attributed partly to greater leaf area expansion.
- Mechanism Soybean tolerance was attributed partly to P absorption through root interception.
