- Association Plant height and number of tillers of rice decreased when red rice competed with rice during active tillering stage.
- Intervention effect The maximum tillering stage of rice competed with red rice was about 10 days earlier than in non-competed rice.
- Intervention effect Yield of rice was significantly reduced in plots competed for 20 days after transplanting or longer.
- Observation In a replacement diagram, the competition between rice and red rice was antagonistic.
- Observation The relative yield total of rice was lower than 1.
- Association Grain number, culm and panicle length of rice were not significantly affected by inter-specific competition.
- Association Rice grain yield reduction was highly correlated with the number of red rice panicles.
- Intervention effect Three hundred red rice panicles were necessary to reduce rice grain yield by 50% relative to the check plot.
