Other claims from this paper (6)
- Intervention effect Total tuber yield increased with nitrogen rate up to 150 kg N ha -1, reaching 20.5 t ha -1, relative to control.
- Intervention effect The lowest ratio of small tubers, 9.86%, was obtained at 150 kg N ha -1, and the ratio of small tubers decreased as N rate increased.
- Intervention effect Total tuber yield decreased by 22% as in-row space increased from 25 to 35 cm.
- Intervention effect The ratio of medium and large tubers increased marginally as in-row space increased from 25 to 35 cm.
- Intervention effect Increased N rate significantly decreased nitrogen use efficiency, nitrogen utilization efficiency and nitrogen uptake efficiency relative to control.
- Association No interaction effect between N rate and plant density was found.
