The present study was conducted at field experiment in Mit Ghamer District, Dakahlia Governorate, Egypt, during 2014/2015 and 2015/2016 seasons. The study aimed to find out the effect of sowing dates (November 15th, November 30th and December 15th), cultivars (Giza 171, Sids 12 and Gemmiza 11) and planting densities (300, 400 and 500 grains/m2) on yield and yield attributes of wheat.The early wheat sowing on 15th Nov. appeared to be produced the highest plant height, spike length, number of grains/spike, weight of grains/spike, 1000-grain weight and grain yield/fad. Varietal differences effected significantly on yield and yield attributes where, Gemmiza 11 cultivar appeared to be produced the highest plant height, spike length, grain weight/spike, 1000-grain weight and grain yield per fad. While Giza 171cultivar tended to produce the highest number of spikes/m2. On other hand, dense planting of 500 grains/m2 obtained the highest number of spikes per m2, as well as, grain yield/fad., as compared with the other two planting densities. While, light density (300 grains/ m2) gave the highest grain number/spike and grain weight /spike. Regarding the significant interaction between the studied factors on almost yield and yield attributes, showed that early sowing on 15th Nov. obtained the highest grain yield/fad., with Gemmiza 11 and Sids 12 cultivars when dense planting of 500 grains/m2 were applied.
