- Intervention effect Cover crop and weed interference significantly reduced sunflower 100-seed weight and seed yield.
- Intervention effect Leaf area index was more sensitive to weed interference and cover crop presence than the other crop traits.
- Intervention effect With F. esculentum as living mulch, sunflower grain yield was reduced by 28% compared with the weed-free plot.
- Intervention effect With M. scutellata as living mulch, sunflower grain yield was reduced by 16% compared with the weed-free plot.
- Intervention effect With V. villosa as living mulch, sunflower grain yield was reduced by 28% compared with the weed-free plot.
- Intervention effect With F. esculentum as living mulch, weed biomass was reduced by 43% compared with the weed-infested check.
- Intervention effect With M. scutellata as living mulch, weed biomass was reduced by 33% compared with the weed-infested check.
- Intervention effect With V. villosa as living mulch, weed biomass was reduced by 25% compared with the weed-infested check.

- Observation Sunflower cultivar Azargol with M. scutellata as cover crop alone had the highest grain yield.
- Observation Sunflower Azargol with V. villosa followed by one weeding had the lowest weed infestation.
