e0“The highest contents of phosphorus (p = 0.967, 0.10%) and potassium (p = 0.038, 1.26%) were recorded in tubers that received 150 kg K2O/ha and 180 kg K2O/ha, respectively.”

- Observation Unfertilized plants had the least shoot biomass, 7.1 t/ha.
- Observation Unfertilized plants yielded 12.7 t/ha tubers, the least.
- Observation The fewest leaves, 136, occurred at 60 kg K2O/ha.
- Observation The fewest tubers, 46, occurred at 90 kg K2O/ha.
- Association Tuber potassium content varied significantly with potassium fertilizer rate.
- Intervention effect Tuber phosphorus content was unaffected by potassium fertilizer rate.
- Observation The highest phosphorus content, 0.10%, occurred at 150 kg K2O/ha, though the rate effect was nonsignificant.
- Association Tuber carotenoid content declined as potassium rates increased.
- Association Tuber carbohydrate content declined as potassium rates increased.
- Association Tuber protein content declined as potassium rates increased.
- Association Tuber crude fiber content increased as potassium rate increased.
- Recommendation The authors concluded that 180 kg K2O/ha performed best in the study area.
- Recommendation The authors recommend testing rates above 180 kg K2O/ha to find the optimum.
