Other claims from this paper (10)
- Intervention effect Conventional tillage gave the least weediness in maize and wheat.
- Mechanism The lower yield in the cultivation system with reduced tillage is attributed to the competition of weeds in maize and wheat.
- Intervention effect The lowest yields in maize and wheat were obtained in the wheat–maize no-tillage system compared with the other systems, at high and low yield levels alike.
- Intervention effect On average over years, the yield decrease in the wheat–maize no-tillage system was 10–15% compared with traditional cultivation.
- Association In wheat, weed cover increased with increasing N fertilizer amounts.
- Association The relation between weeds and N fertilizer is similar to the second power equation of the yield curve.
- Association In maize trials, weed coverage did not differ significantly between N treatments (25–30%).
- Recommendation With reduced soil cultivation, the practice of weed control and fertilization for maize and wheat needs to be modified and harmonized.
- Recommendation Scientifically well-established weed control and fertilization methods should be applied instead of a schematic process.
- Recommendation Data collection of weeds, a survey of dominant species, special herbicide combinations and precision agriculture should be considered in sustainable agriculture.
