- Intervention effect Weed-free sorghum outyielded its weedy counterpart by 42.2%.
- Intervention effect At high sorghum planting density, applying 112 kg N ha-1 did not improve grain yield.
- Intervention effect Applying 112 kg N at high sorghum planting density increased sorghum head number and height.
- Recommendation Strategies for long-season Palmer amaranth control are needed to protect sorghum yield from weed competition.
