Abstract:
Present investigation was conducted at farmer’s field in Nainital district of Uttarakhand to know the response of two potato varieties to various levels of nitrogen yield attributes and yield of potato tubers during the 2020-2021. Data revealed that the plant emergence per cent, plant height, number of tubers per hectare, tuber yield per hectare and harvest index recorded maximum with variety Kufri Himalini while number of haulms/hill was recorded with variety Kufri Jyoti. The result showed a significant effect of nitrogen levels on yield attributing characters and yield. The application of 100kg N/ha gave maximum number of tubers, total tuber yield per hectare and harvesting index. Thus it can be concluded that the variety Kufri Himalini with application of 100 kg N/ha is suitable for having higher yield of potato in Northwestern hills of Uttarakhand.
