A field experiment was conducted for two consecutive seasons during 2011/2012 and 2012/2013 at Research Station Farm, New Halfa, to investigate the effect of five sowing dates and three cultivars of wheat (Triticum aestivum L.) on yield and some of its related traits. The experiment consisted of fives sowing dates: 15th October, 30th October, 15th November, 30th November and 15th December, and three wheat cultivars: Condor (early mature), Nebta (medium mature) and Debeira (late mature). Split-plot design with three replications was used to arrange the treatments. The results showed that the early or delayed sowing dates significantly and negatively reduced yield attributes. Early sowing date (15th October) or delayed sowing (15th December) substantially reduced grain yield compare with the optimum sowing dates (mid and late of November). Cultivars showed non-significant effect in the grain yield per hectare. nevertheless, Debeira cultivar showed consistency and best performance in the studied sowing dates and it was stable in most of traits except maturity (it delayed in maturity) followed by Condor and Nebta cultivars.
