Abstract: A field experiment entitled “Impact of different Sources of Nitrogen on Growth and Economics of Potato (Solanum tuberosum L.)” was conducted during rabi season 2018-19 at, Fruit Research station, Entkhedi, Bhopal, Madhya Pradesh. Bhopal is located at 26013’ north latitude and 7404’ east longitude and 208 m above mean sea level. It lies in the central part of Madhya Pradesh state enjoying sub-tropical climate. The topography of the experimental field was plain with good irrigation facilities. The experiment laid down in seven treatments with control i.e. T0- Nitrogen 00 kg/ha, T1- Nitrogen 20 kg/ha, T2- Nitrogen 60 kg/ha, T3- Nitrogen 100 kg/ha, T4- Nitrogen 140 kg/ha, T5- Nitrogen 180 kg/ha and T6- Nitrogen 220 kg/ha with three replication. The experiments was analyzed at Randomized Block Design. Growth Characteristics i.e. Days of germination, Number of shoots per plant at 25 and 50 days after sowing, Height of plant (cm) at 25, 50 and 75 days after sowing, Number of compound leaves/ plant at 25, 50 and 75 days after sowing and net returns and B:C ratio of potato. The result revealed that the application of nitrogen in the form of treatment (T6) Nitrogen 220 kg/ha + Kufri Chipsona-3 was found to be superior to other nitrogen levels in all potato growth and economics parameters.
