Abstract: The experiment was conducted during November 2012 to March 2013 in experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to find out the consequence of irrigation levels on growth, yield attributes and yield of wheat .Four different irrigation levels viz.I 0 : No irrigation i.e. control; I 1 : Irrigation at 20 days after sowing (DAS) at crown root initiation stage; I 2 : Irrigation at 55 DAS at flowering stage) and I 3 : Irrigation at 75 DAS at grain filling stage were used in the experiment using Randomized Complete Block Design with three replications.Results revealed that maximum dry matter content (18.8 g/plant), crop growth rate (CGR) (13.5 g m -2 day -1 ), relative growth rate (RGR) (0.024 g m -2 day - 1 ) were found from I 1 which was statistically identical with I 2 whereas minimum from I 0 .Plant height (80.7 cm), number of tiller (4.9/hill), number of spike (4.7/hill), number of spikelets (18.5/spike), spike length (19.2 cm), filled grains (29.3/spike), total grains (31.3/spike), 1000grains weight (44.4 g), yield (grain 3.4 t/ha, straw 5.7 t/ha and biological 9.1 t/ha) and harvest index were correspondingly showed higher results as of growth characters.
