In the present work, we evaluated four bread wheat cultivars, three nitrogen (N) fertilization amounts, and two planting dates. The experiment was conducted at Almarashda Agricultural Research Station during the 2018-19 and 2019-20 growing seasons to determine the effect of two sowing dates (November 25th and December 25th) and three nitrogen fertilization rates (125, 100, and 75 kg N Fadden-1) on the phenology, grain yield, and grain component composition of four Egyptian bread wheat cultivars (Triticum aestivum, L), namely Sids 14, Shandaweel 1, Giza 171, and Gemm The research employed a split-split plot design with three duplicates. The results indicated that seeding late (25 December) considerably reduced all characters in both seasons when compared to the optimum sowing date (25 November), except for 100-grain weight, which remained the same. All attributes were improved as the N fertilization level was increased from 75 to 125 kg N Fadden-1. Sids 14 outperformed the other cultivars in practically all evaluated traits including grain yield.
