Abstract: A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2015 to March 2016 to evaluate the effect of nitrogen (N) fertilizer on the yield and quality of wheat cv. BARI gom30. The experiment comprised four levels of Nitrogen (N) viz., 0, 50, 100, 150 kg/ha. The experiment was laid out in a randomized complete block design with three replications. The experimental result showed that there were significant differences in grain yield and straw yield due to the application of Nitrogen (N), although some of the yield attributes were not found significant. The highest plant height (96.23 cm), number of total tillers/plant (4.58), number of effective tillers/plant (4.00), spike length (10.16 cm), number of fertile spikelets/spike (48.92), number of grains/panicle (20.11), 1000-grain weight (49.78 g), grain yield (5.25 t/ha) and straw yield (6.30 t/ha) were obtained from 100 kg N/ha. The lowest plant height (84.00cm), number of effective tillers/plant (2.33), grain yield (4.25 t/ha) and straw yield (5.42 t/ha) were observed with the application of 0 kg N/ha. The highest number of sterile spikelets/spike (3.17) was found under control and highest harvest index (46.50%) was obtained from 150 kg N/ha. The overall results of the present study demonstrated that wheat may be grown successfully for obtaining maximum yield with the application of 100 kg N/ha.
