Other claims from this paper (9)
- Intervention effect At 20 plants m−2, parthenium weed reduced maize leaf area index by 15%.
- Intervention effect At 20 plants m−2, parthenium weed reduced ears per plant of maize by 21%.
- Intervention effect At 20 plants m−2, parthenium weed reduced thousand grain weight of maize by 12%.
- Intervention effect At 20 plants m−2, parthenium weed reduced maize biological yield by 15%.
- Intervention effect At 20 plants m−2, parthenium weed reduced maize grain yield by 18%.
- Intervention effect Parthenium weed densities of 5-15 plants m−2 caused 8-10% grain yield losses in maize.
- Association Parthenium weed biomass increased linearly with weed density.
- Association Parthenium weed biomass had strong negative correlations with maize yield and yield-related traits.
- Recommendation Parthenium weed density should be reduced below 15 plants m−2 to avoid substantial maize yield losses.
