A field experiment was conducted at Main Experimental Station of Narendra Deva University of Agriculture & Technology, (Kumarganj), Ayodhya (U.P.) during Rabi season of 2016-17 to study the performance of barley varieties under various nitrogen levels in sodic soil. The trial was laid out in Split Plot Design. Nitrogen levels (60, 75 and 90 kg N ha-1) were kept in main-plots and varieties (RD-2907, RD-2552, NDB-1173 and RD-2794) in sub-plots with three replications on sodic soils having low organic carbon (0.38 g kg-1), available nitrogen (185.0 kg ha-1), phosphorus (15.25 kg ha-1) and potassium (265 kg ha-1). Data manifested to nitrogen content and uptake of barley grain and straw as influenced by nitrogen levels and varieties. Maximum nitrogen content (1.68) in grain, (0.54%) in straw determined with application of 90 kg N ha-1 which was at par with the dose of 75 kg N ha-1 and lowest with 60 kg N ha-1. The Maximum nitrogen uptake in grain (47.13 kg ha-1) and straw (24.80 kg ha-1) was recorded under the supply of 90 kg N ha-1 which was significantly higher than 75 and 60 kg N ha-1. There was no significant difference in term of nitrogen content in grain due to different varieties of barley crop. Maximum nitrogen content (0.55) in straw was recorded in variety RD-2907 which was at par with RD-2552 (0.54%) and significantly maximum over rest of the varieties. Among the varieties of barley, maximum nitrogen uptake by grain and straw (48.31 and 25.25 kg ha-1, respectively) was recorded in variety (RD-2907) which was at par with (24.52) RD-2552 and significantly superior to RD-2794 and NDB-1173. Nitrogen and protein content in grain increased with increasing levels of nitrogen. Maximum nitrogen content (1.68%) and protein content (10.54%) in grain was observed with 90 kg N ha-1. The varieties had no significant effect on nitrogen and protein content in grain.
