Other claims from this paper (16)
- Intervention effect Si application significantly increased tobacco biomass by 19.5%-26.53% relative to S0.
- Intervention effect Si application significantly increased tobacco plant height at button stage by 15.38%-19% relative to S0.
- Intervention effect Si application significantly increased nitrogen fertilizer utilization efficiency by 27.42%-43.71% relative to S0.
- Intervention effect Si application significantly increased potassium fertilizer utilization efficiency by 40.25% - 44.63% relative to S0.
- Intervention effect Si application enhanced single-leaf weight and leaf area of tobacco relative to S0.
- Intervention effect Si application reduced leaf density and midrib ratio of tobacco relative to S0.
- Intervention effect Si application improved the sugar-alkali ratio and potassium-chloride balance of tobacco leaves relative to S0.
- Intervention effect The S50 treatment increased reducing sugar content in upper tobacco leaves by 15.21%.
- Intervention effect The S100 treatment decreased chlorine content in middle tobacco leaves by 11.11%.
- Intervention effect S50 gave the highest proportion (94.75%) of medium and high-quality tobacco leaves among all treatments.
- Intervention effect The S50 treatment increased tobacco yield by 15.70% compared with S0.
- Intervention effect The S50 treatment boosted tobacco output value by 30.76% compared with S0.
- Intervention effect Excessive Si application (3000 kg/ha) increased tobacco nicotine levels.
- Intervention effect Excessive Si application (3000 kg/ha) disrupted the sugar-alkali ratio of tobacco leaves.
- Association Excessive Si application (3000 kg/ha) is associated with elevated leaf irritancy of tobacco, according to the authors.
- Recommendation Moderate Si application (750–1500 kg/ha) is recommended for enhancing tobacco yield and quality.
