Other claims from this paper (7)
- Intervention effect KCl raised marketable tuber yield by 10.3% relative to potassium sulfate.
- Intervention effect KCl raised total tuber yield by 9.0% relative to potassium sulfate.
- Intervention effect KCl lowered tuber-specific gravity.
- Intervention effect Potassium magnesium sulfate improved potato yield and quality.
- Intervention effect The highest potassium rate lowered tuber-specific gravity tenfold in 2022 relative to 224 kg K2O per hectare.
- Intervention effect The highest potassium rate lowered tuber-specific gravity threefold in 2023 relative to 224 kg K2O per hectare.
- Recommendation The authors recommend optimizing potassium rate and source to balance yield and tuber quality.
