Other claims from this paper (10)
- Intervention effect Average potato yield increased significantly with nitrogen supply up to 225 kg N ha-1 and then tended to decrease slightly.
- Intervention effect Tuber yield of Kufri Shailja and Kufri Jyoti increased significantly up to 225 kg N ha-1 and decreased with further nitrogen.
- Intervention effect Yield of Kufri Himalini increased with nitrogen up to 300 kg N ha-1.
- Intervention effect The yield increment of Kufri Himalini from 225 to 300 kg N ha-1 was not significant.
- Intervention effect Applying 150 kg N ha-1 instead of 225 kg N ha-1 decreased average potato tuber yield by 5.3%.
- Intervention effect Applying 75 kg N ha-1 instead of 225 kg N ha-1 decreased average potato tuber yield by 18.7%.
- Intervention effect Applying no nitrogen instead of 225 kg N ha-1 decreased average potato tuber yield by 65.1%.
- Association Nitrogen use efficiency of Kufri Himalini was higher at all N levels.
- Recommendation About 225 kg N ha-1 is the optimum nitrogen dose for higher potato tuber yield irrespective of cultivar.
- Observation Kufri Himalini was the most efficient cultivar in nitrogen use.
