Other claims from this paper (15)
- Association Density and potassium fertilizer significantly affected fresh potato and dried potato yields.
- Association Density and potassium fertilizer significantly affected starch content, tuber dry matter rate and rate of large and medium tubers.
- Association At densities no greater than 57.0 thousand plants/ha, fresh and dried potato yields rose with potassium application.
- Association At densities no greater than 57.0 thousand plants/ha, dry matter content rose with potassium application.
- Association At low potassium levels, fresh and dried potato yields increased with planting density.
- Association At high potassium levels, fresh and dried potato yields first increased then declined with density.
- Intervention effect High potassium at low density improved starch yield.
- Intervention effect No potassium gave the lowest fresh potato yield and dry matter.
- Intervention effect No potassium produced the highest tuber dry matter rate.
- Intervention effect Low density with potassium increased the rate of large and medium sweet potatoes.
- Intervention effect High density and high potassium decreased the rate of large and medium sweet potatoes.
- Observation The highest fresh potato yield was 51483.98 kg/ha at the specified fertilizer and density combination.
- Observation The highest dried potato yield was 15555.75 kg/ha at the specified treatment combination.
- Observation The highest starch yield was 10251.24 kg/ha at the specified treatment combination.
- Recommendation The authors concluded that lower density with more potassium increases commodity rate.
