- Intervention effect Preharvest nitrogen application advanced the onset of ratoon tiller growth.
- Intervention effect Preharvest nitrogen application shortened the development period of tiller buds and young panicles at the upper nodes.
- Intervention effect Preharvest nitrogen application did not affect ratooning ability or ratoon crop growth at lower nodes.
- Mechanism Higher ratoon yield after preharvest nitrogen results from advanced ratoon development and enhanced ratooning ability at the upper nodes.
