Abstract
Two field experiments were conducted at Abazah Village, Faqous District, Sharkia Governorate, Egypt during 2013/2014 and 2014/2015 growing seasons, to study the effect of three sowing dates (November 10th, November 30th and December 20th), three nitrogen fertilizer levels (60, 90 and 120 kg N/fad.) and four wheat cultivars (Gemmizea 11, Sids 12, Giza 164 and Misr 1) on yield and yield attributes of wheat under sandy soil conditions. Each experiment included 36 treatments, which were the combinations of three sowing dates, three nitrogen fertilizer levels and four wheat cultivars. A split-split plot design with three replicates was used where; the main plots were devoted to sowing dates while the sub plots were occupied by nitrogenfertilizer levels whereas wheat cultivars were allotted in the sub-sub plots. The obtained results revealed that plant height, number of spikes /m2, spike length,  number of spikelets/spike, number of grains/spike, 1000-grain weight as well as  grain, straw and biological yields/fad., were significantly higher on November,30th  sowing as compared to other sowing dates. Nitrogen fertilizer level affected significantly all studied traits. Since, increasing nitrogen fertilizer level up to 120 kg N/fad., significantly increased plant height, spike length, number of spikelets/spike, number of grains/ spike as well as grain, straw and biological yields/fad., while 1000-grain weight significantly decreased. On the other side, number of spikes /m2 was responded only to nitrogen up to 90 kg N/fad. (Combined data). Misr 1 cv. recorded the maximum plant height, number of spikes/m2 as well as grain, straw and biological yields/fad., but without significant differences than Gemmizea 11 in grain and biological yields.  Otherwise Sids 12 surpassed other cultivars in spike length, number of spikelets/spike, number of grains/spike and 1000-grain weight.
