Other claims from this paper (10)
- Observation Yield ability varied widely, with AERON 1 leading at 2.72 Mg/ha.
- Observation Mean weed pressure across rice germplasm was 244 g/m2 versus 596 g/m2 in weed monoculture.
- Intervention effect AERON 1 was most suppressive and decreased weed dry weight by 76%.
- Observation Weed-inflicted relative yield loss ranged from 23 to 53%.
- Observation AERON 1 allowed the least yield penalty.
- Association Faster early height growth, vigor and aboveground biomass were strongly negatively associated with weed biomass.
- Association Tillering ability correlated positively with weed biomass.
- Association Plant erectness was not correlated with weed biomass.
- Association No tradeoff between weed suppression and yield potential was detected.
- Recommendation The authors support weed-competitive cultivars for sustainable management and breeding aerobic rice by combining competitiveness traits.
