SUMMARY
Field experiment was conducted during the rabi season of 2010-11 to find out the response of three barley varieties to four doses of nitrogen under acidic soil conditions of Manipur. The crop was sown on 28 November 2010, cut for green fodder on 4 February, 2011 and finally harvested for grain on 20 April, 2011. The total rainfall received during the cropping season was 463 mm. The results revealed that among the varieties, BHS-380 recorded remarkably higher green and dry fodder with the application of 60 kg N/ha. The number of effective tillers, number of grains per panicle and panicle length recorded were significantly higher in the variety HBL-276 with the application of nitrogen up to 60 kg/ha. Significant increase in grain yield of barley was also observed in the same treatment. Highest profit could be obtained from the variety HBL-276 with the application of 60 kg N/ha.
