The present investigation was conducted at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate. The station is sited at 31^0ₒ -57^‾/ N latitude and 30⁰-57^‾ longitude. It has an elevation of about 20 m above sea level and it represents the conditions and circumstances of the middle north Nile Delta. A field experiment was carried out during the season 2014/2015   to study the effect of number of irrigations and sowing date on wheat yield, its components and some water relationships. A split plot design with four replications was used. Sowing date were 15/11 ( D₁),  30/11  ( D₂)  and 15/12 ( D₃) occupied the main plots, while irrigation regime were I₁ = 5 irrigations , I₂ = 4 irrigations and I₃ = 3 irrigations,  arranged in sub-plots. The obtained results can be summarized as follows: The highest values of water applied and water consumptive use were recorded under ( I₁) .On the contrary, the lowest values were recorded under treatment,( I₃ ).15^th November as a sowing date significantly increased grain yield, straw yield, spike length, number of tiller, plant height and 1000 grain weight by 18.6, 17.4, 26.7, 17.8, 9.9 and 20.3 % compared to sowing on 15^th December (D₃). Also sowing on 15^th November significantly increased water productivity by 27.2 %.
