e2“On the contrary, A. palmeri 's dry biomass was reduced more when seeded in the late stage of cotton with the contribution of intraspecific competition”
e0“Pot experiments showed that early competition caused a higher decrease in cotton height and dry weights compared to late competition”

Other claims from this paper (7)
- Intervention effect Early A. palmeri competition caused a higher decrease in cotton height and dry weights than late competition.
- Association In field experiments, cotton height, node number and boll number significantly decreased with increasing A. palmeri densities.
- Association Cotton yield decreased by 39%-51% with 1 A. palmeri per one-meter row in 2020 and 2021.
- Association Cotton yield decreased by 51%-63% with 2 A. palmeri per one-meter row in 2020 and 2021.
- Association Cotton yield decreased by 79%-75% with 4 A. palmeri per one-meter row in 2020 and 2021.
- Association Even one A. palmeri per meter of cotton row significantly reduced yield.
- Recommendation The authors recommend implementing management strategies for this weed in cotton.
