Other claims from this paper (16)
- Observation Lettuce variety yields ranked Guasihong, Tip, Runnong, Double-tip, then Dabaijia.
- Observation Dabaijia had the highest nitrogen yield efficiency at a medium nitrogen level.
- Observation Double-tip had the highest nitrogen yield efficiency at a higher nitrogen level.
- Observation Dabaijia had the highest potassium yield efficiency, followed by Double-tip.
- Intervention effect Adding nitrogen at N15 K15 reduced yield in all five varieties.
- Intervention effect Adding potassium at N20K10 reduced yield in all five varieties.
- Observation Leaf nitrate concentration ranked Tip, Runnong, Double-tip, Dabaijia, then Guasihong.
- Intervention effect Nitrogen application increased leaf nitrate concentration.
- Observation Dabaijia and Guasihong had the greatest nitrate increases at N20K10.
- Association Leaf nitrate at N15K10 was markedly below N15K5.
- Observation Runnong, Guasihong, and Dabaijia had higher vitamin C content.
- Observation Tip had the highest reductive sugar content, closely followed by Guasihong.
- Observation Runnong had the lowest reductive sugar content.
- Recommendation Guasihong was judged best overall for quality and yield.
- Recommendation N15K10 was recommended for Double-tip, Guasihong, Dabaijia, and Tip.
- Recommendation N20K10 or N15K15 was recommended for Runnong.
