Abstract: A field experiment was conducted under loamy sand soil during two consecutive Rabi seasons of 2016-17 and 2017-18 at Research Farm, Rajasthan Agricultural Research Institute, Sri Karan Narendra Agriculture University, Durgapura, Jobner. The experiment comprises four irrigation scheduling treatments (Irrigation at 0.6 ETc, 0.8 ETc, 1.0 ETc and 1.2 ETc), three cultivars (Raj 4120, Raj 4079 and Raj 4238) and three dates of sowing (15th November, 30th November and 15th December) assigned, respectively to main plot, sub plot and sub-sub plots were replicated three times in split plot design. The results revealed that spike length and grains per spike of wheat crop were significantly influenced by different dates of sowing, varieties and irrigation schedules. Among different varieties, sowing dates and irrigation schedules, the maximum spike length, number of spikelet per spike, grains per spike and grain yield was recorded with variety Raj 4079 sowing of wheat on 15th Nov. and irrigation scheduling at 1.2 Etc, respectively. Sowing of wheat variety Raj 4079 on 15th Nov along with 1.2 ETc irrigation scheduling resulted in maximum spike length (12.77 cm), grains per spike (50.64), spikelets per spikes (19.04) and grain yield (5968 kg ha-1).
