Other claims from this paper (8)
- Intervention effect Increasing the nitrogen supply increased dry weight and area of tobacco leaves.
- Intervention effect Increasing the nitrogen supply did not increase nitrogen concentration of tobacco leaves, especially in the middle plant position.
- Intervention effect Split application of nitrogen significantly increased nitrogen concentration of tobacco leaves in the middle plant position.
- Intervention effect The restricted watering treatment reduced dry weight and area of tobacco leaves.
- Intervention effect Late application of nitrogen gave relatively high nitrogen concentrations in the upper leaves of tobacco.
- Intervention effect Most late applied nitrogen was incorporated into upper tobacco leaves in a labelled nitrogen experiment.
- Observation Leaf nitrogen concentration of tobacco changed from removal of the inflorescence to final harvest.
- Intervention effect Split application of nitrogen produced the best cured leaf quality of tobacco.
