Other claims from this paper (4)
- Association Parthenium weed biomass increased significantly as density and competition duration rose.
- Association Increasing parthenium density had a linear negative effect on sorghum growth, yield and yield-contributing traits.
- Intervention effect Season-long competition with parthenium reduced sorghum grain yield by 81% relative to weed-free treatment.
- Recommendation The authors recommend managing parthenium below 5 plants per square metre throughout sorghum growth.
