Other claims from this paper (13)
- Observation The paddy plots contained 52 weed species.
- Observation Weed density peaked in September at 105 pl/m2.
- Association Weedy plots had significantly reduced straw yield.
- Association Weed species richness was negatively correlated with straw yield.
- Association Crop weed competition reduced straw yield by 13% to 38%.
- Association Crop weed competition reduced grain yield by 25% to 47%.
- Association Weed growth changed soil pH.
- Association Weed growth reduced soil nitrogen and phosphorus content.
- Intervention effect Dominant weed extracts had a weak effect on paddy seed germination.
- Intervention effect Most weed extracts inhibited paddy root and shoot elongation.
- Observation Root elongation was more sensitive to allelopathic inhibition than shoot elongation.
- Intervention effect Stem extracts caused higher inhibition of paddy seedling growth than leaf and root extracts.
- Intervention effect For Ageratum conyzoides, root extract had the highest inhibition.
