Other claims from this paper (12)
- Observation Cenchrus was the stronger competitor in all treatments.
- Observation In all treatments relative yield total exceeded unity.
- Intervention effect When N was limiting, the weights per plant of the grass in mixtures were greater than those in monoculture.
- Observation Legume weights per plant in mixtures were close or equal to those in monoculture.
- Mechanism The grass experienced hardly any competition for N from the legume, which was self-sufficient in its N supply.
- Association Severe N limitation prevented the grass from depressing the legume in the competition for other resources.
- Association The positive response of the legume to P (P:N0) was just enough to enable stable coexistence.
- Association Where N was applied the grass had a strong advantage in competition for P.
- Association Where N was applied the grass had a strong advantage in light competition.
- Mechanism The rapid growth of C. biflorus was concluded to enable it to capture resources early, making it the stronger competitor.
- Observation Alysicarpus ovalifolius grew more slowly than the grass.
- Observation Alysicarpus ovalifolius was adapted to survive in conditions of low nitrogen availability.
