Abstract: The experiment was conducted at the crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh, during Rabi season from November 2001 to March 2002 to investigate the effect of irrigation frequencies on theyield and yield attributes of the wheat cultivar ‘Shatabdi`. Irrigation treatments were given as T0=no irrigation (control), T1=one irrigation at 21 DAS, T2=two irrigations at 21 and 45 DAS, T3=three irrigation at 21, 45 and 60 DAS and T4=four irrigation at 21, 45, 60 and 75 DAS. The experiment was laid out in a randomized complete block design where each treatment was replicated three times. Significant effects were observed on plant height, number of effective tillers per hill, spike length, number of spikelets per spike filled grains per spike due to different levels of irrigation. Two irrigations at 21 and 45 DAS significantly enchanced the growth, yield attributes and yield of wheat over other treatments. As a result grain yield (3.52 t/ha), straw yield (4.22 t/ha) and harvest index (45.25%) were significantly higher at T2 treatment than those of other treatments.
