Other claims from this paper (10)
- Observation The dominant beet cropping interval was at least four years and varied by region.
- Intervention effect Cropping intervals of two, three and at least four years did not affect sugar yield.
- Observation Winter wheat and winter barley were the predominant preceding crops across Germany.
- Intervention effect Sugar beet yielded 5% more after pea than after maize.
- Intervention effect Sugar yield did not differ significantly between pea and winter wheat preceding crops.
- Intervention effect Sugar yield did not differ significantly between wheat and maize preceding crops.
- Intervention effect High nitrogen fertilizer doses did not fully compensate for reduced growth after maize.
- Recommendation The findings do not support major yield loss from reducing rotation interval from three to two years.
- Recommendation Short maize and sugar beet rotations might increase Rhizoctonia root rot risk.
- Recommendation Pea preceding crops may allow higher beet yield at lower nitrogen fertilizer doses.
