- Intervention effect Co-culture with barnyardgrass treatment T2 reduced grain yield of the indica rice cultivar by 10.8% relative to the weed-free control.
- Intervention effect Co-culture with barnyardgrass treatment T3 reduced grain yield of the indica rice cultivar by 21.9% relative to the weed-free control.
- Intervention effect Co-culture with barnyardgrass treatment T1 reduced grain yield of the japonica rice cultivar by 39.7% relative to the weed-free control.
- Intervention effect Co-culture with barnyardgrass treatment T2 reduced grain yield of the japonica rice cultivar by 25.3% relative to the weed-free control.
- Intervention effect Co-culture with barnyardgrass treatment T3 reduced grain yield of the japonica rice cultivar by 47.3% relative to the weed-free control.
- Intervention effect Treatment T4 (E. colonum) showed no significant difference in rice grain yield compared with the weed-free control.
- Intervention effect Treatment T1 significantly reduced rice dry matter accumulation at maturity, flag leaf photosynthetic rate and root oxidation activity.
- Intervention effect Treatment T2 significantly reduced rice dry matter accumulation at maturity, flag leaf photosynthetic rate and root oxidation activity.
- Intervention effect Treatment T3 significantly reduced rice dry matter accumulation at maturity, flag leaf photosynthetic rate and root oxidation activity.
- Intervention effect Treatment T1 significantly reduced ATPase activity in rice grains at the filling stage.
- Intervention effect Treatment T2 significantly reduced ATPase activity in rice grains at the filling stage.
- Intervention effect Treatment T3 significantly reduced ATPase activity in rice grains at the filling stage.
- Intervention effect There was no significant difference between T4 and the control CK in rice dry matter accumulation at maturity, flag leaf photosynthetic rate and root oxidation activity.
- Intervention effect There was no significant difference between T4 and the control CK in ATPase activity in rice grains.
- Intervention effect All barnyardgrass treatments had no effect on final tiller number and plant height of rice.
- Observation The negative effect of barnyardgrass on rice growth and yield differed among the four barnyardgrass species, in the order T3 > T1 > T2 > T4.
- Mechanism Barnyardgrass reduced flag leaf photosynthetic rate, root oxidation activity and grain ATPase activity, which the authors say resulted in lower final productivity of rice.
