Abstract

Field investigation was carried out to study the effect of different nitrogen levels on growth and yield parameters in potato var. Kufri Surya. The experiment was laid out in a randomized block design with treatments consisting of six nitrogen levels replicated four times. Growth parameters like plant height, number of leaves per plant, number of shoot per plant, fresh and dry weight of shoot per plant and yield attributing parameters like number of stolon, fresh and dry weight of tuber per plant increased with an increase in nitrogen levels with maximum values being obtained on application of highest nitrogen level (375 kg N/ha). However, highest values for number of tuber per plant and per plot as well as tuber yield per plot and per hectare was recorded on application of 225 kg N/ha. The highest net returns (Rs. 117323) and maximum B: C ratio (1.42) was recorded on application of 225 kg N/ha.
