Other claims from this paper (8)
- Intervention effect Season-long sunflower density of 3 plants per square metre reduced wheat yield by 11%.
- Intervention effect Season-long sunflower density of 9 plants per square metre reduced wheat yield by 19%.
- Association Sunflower was more competitive with late than early May seeded wheat.
- Intervention effect Sunflower competition until wheat flag-leaf stage reduced wheat yield by 22%.
- Intervention effect Wheat yields were similar with MCPA, bromoxynil, or their combination.
- Intervention effect MCPA controlled sunflower more slowly than bromoxynil or the combination.
- Recommendation Authors advise early planting of wheat after sunflower.
- Recommendation Authors advise removing sunflower at densities of at least nine plants per square metre before flag-leaf stage.
