A field investigation on effect of nitrogen levels on potato variety Kufri Surya was conducted at Potato Research Station, SDAU, Deesa, Gujarat during rabi for three years (2011-12, 2012-13 and 2014-15). Results indicated that application of 150 kg N/ha improved tuber yield and crop productivity with higher remuneration and efficient use of phosphorus, potassium and water. However agronomic use efficiency of nitrogen decreased with subsequent increase in nitrogen levels.
