Other claims from this paper (13)
- Intervention effect Tillage and crop establishment methods altered weed and seedbank composition.
- Intervention effect Zero-till direct-seeded rice reduced Cyperus iria emergence by 62% versus tilled systems.
- Intervention effect Zero-till direct-seeded rice reduced Echinochloa colona emergence by 82–90% versus tilled systems.
- Intervention effect Zero-till direct-seeded rice reduced total weed emergence by 81–83% versus tilled systems.
- Intervention effect The rice and wheat intensification system favored E. colona in rice.
- Intervention effect Wheat intensification favored Phalaris minor and Solanum nigrum.
- Intervention effect Zero-till rice and wheat reduced total weed seedbank by 62%.
- Observation Most C. iria seeds were in the 0–15 cm soil layer (72%).
- Observation Grasses in the 0–15 cm soil layer comprised 62% of grass seeds.
- Observation Broad-leaved weeds in the 0–15 cm soil layer comprised 64% of their seeds.
- Intervention effect Zero-till direct-seeded rice had 13% lower grain yield than conventional puddled transplanted rice.
- Intervention effect Zero-till wheat under triple zero-till produced 11.5% higher grain yield than wheat intensification.
- Recommendation Triple zero-tillage is proposed to reduce weeds and seedbank while increasing system productivity.
