Present experiment was conducted during Rabi season 2016-17 and 2017-18 at Research farm, Rajasthan Agricultural Research Institute, Sri Karan Narendra Agriculture University, Durgapura, Jobner, Rajasthan to find out the response of wheat cultivars to irrigation scheduling under different sowing dates. Thirty-six treatment combinations were investigated. Treatments comprises four irrigation levels: I1 (0.6 Etc), I2 (0.8 Etc), I3 (1.0 Etc) and I4 (1.2 Etc), three cultivars: C1 (Raj-4120), C2 (Raj-4079) and C3 (Raj-4238) and three dates of sowing: D1 (15th Nov.), D2 (30th Nov.) and D3 (15th Dec.) in split plot design. A critical examination of results showed that irrigation applied at 1.2 Etc (I4) recorded the maximum values of yield parameters (effective tiller per metre row length, number of grains per spike, length of spike per spike, spikes per metre square area and test weight) and yields. Further results on cultivar indicated that the Raj 4079 proved significantly superior over Raj 4120 and Raj 4238 with respect to all yield attributes. However, results showed that sowing of wheat on 15th November gave higher values for yield attributes and yield.
