Other claims from this paper (8)
- Intervention effect Tomato reduced barnyardgrass seed production.
- Association The reduction in barnyardgrass seed production depended on both tomato density and barnyardgrass density.
- Observation In the absence of tomato, barnyardgrass produced over 200,000 seeds m−2 in 1993.
- Observation In the absence of tomato, barnyardgrass produced over 500,000 seeds m−2 in 1994.
- Observation Seed production was almost 700,000 seeds m−2 when the weed density exceeded 50 plants m−1 of row.
- Intervention effect The clumped spatial distribution reduced weed seed production by 30 to 50% at weed densities of 1 to 5 plants m−1 of row, compared with regular and random arrangements.
- Intervention effect Seed production differed only minorly between regular and random spatial arrangements.
- Observation Barnyardgrass seed production at the single-season economic threshold density in tomato was sufficient to maintain the seedbank at a level requiring high weed control in later crops.
