The experiment was conducted with 14 treatments of different nitrogen sources, Azotobacter, phosphorus solublizing bacteria in randomized block design with three replications. The periodic growth parameters (plant height, leaf area index, dry matter accumulation and tillering) and yield attributes (length of ear head and number of grains per ear head) increased with increasing dose of nitrogen with 100 per cent N inoculated with Azotobacter and PSB but had no effect on test weight. The grain and straw yield increased significantly by increasing nitrogen dose with 100 per cent inoculated with Azotobacter and PSB. Nitrogen application and Azotobacter and PSB had no effect on harvest index. Residual nitrogen in soil increased with increasing nitrogen dose i.e. 100 per cent inoculated with Azotobacter and PSB. Nitrogen content in grain and straw increased significantly with 100 per cent inoculated with Azotobacter and PSB. Crude protein content in grain increased significantly with 100 per cent inoculated with Azotobacter and PSB. Vermicompost and inorganic fertilizer affected the malt yield. Higher fertilizer of nitrogen led to significant reduction in malt yield. Malt homogeneity, bold grain percentage increased significantly with 100% inorganic fertilizer inoculated with Azotobacter and PSB as compared to various treatments. Net income increased significantly with increasing nitrogen dose with 100 per cent inoculated with Azotobacter and PSB (Rs. 6231ha-1). On the basis of one year results it may be suggested that barley crop should be grown by inoculating seed with Azotobacter and phosphorus solublizing bacteria 60 kg N ha-1.enBarley, Integrated nutrient management, Azotobacter, Phosphorus solublizing bacteria, Inorganic fertilizer, Vermicompost, Yield, malt content, Bold, Thin grain percentage, EconomicsThesis
