Other claims from this paper (14)
- Observation In mixtures, modern cultivar yield decreased.
- Association Per-plant cultivar yield fell as the older cultivar proportion increased.
- Association Mixture population yield fell as the older cultivar proportion increased.
- Observation Competitive ratio reflected competitive ability differences among three maize cultivars.
- Association Population competition pressure rose with the older cultivar proportion.
- Association Biomass yield was negatively correlated with population competition pressure.
- Association Grain yield was negatively correlated with population competition pressure.
- Association Harvest index was negatively correlated with population competition pressure.
- Association Thousand-kernel weight was negatively correlated with population competition pressure.
- Association Kernel number per plant was negatively correlated with population competition pressure.
- Mechanism Inter-cultivar competition affects maize productivity.
- Mechanism Increasing population competition pressure decreases translocation of assimilates to grain.
- Mechanism Increasing population competition pressure ultimately reduces yield.
- Recommendation The authors recommend breeding a communal ideotype that performs poorly in competition.
