Abstract
Field experiments were carried out at the experimental farm of Gemmeiza Agriculture Research Station A.R.C, El-Gharbeia Governorate , Egypt. This investigation was performed during the two successive growing seasons 2013/14and 2014/15 to study the effect of three nitrogen levels on yield and yield components of eight common wheat varieties. The significantly highest means of yield and yield components were obtained from fertilized by 100 unit /fad in both seasons, while the lowest one was obtained from 50 unit /fad nitrogen fertilizer in both seasons, except harvest index which was significant greater at 75 unit /fad than at 100 unit /fad specially in the second season and grain yield, where its values were not differ significantly at both N rates in both seasons. The genotype Gemmeiza-11 recorded the highest values for number of grains/spike, 1000–grain weight, harvest index and grain yield/plot, followed by Gemmeiza-9 for number of grains/spike, 1000–grain weight. On the other hand, Sohag- 3 recorded the lowest values for number of grains/spike and 1000–grain weight in both seasons. Wheat genotype Gemmeiza-10 recorded the highest number of spikes / m2 in both seasons ,while Banei Sweif 5 recorded the lowest one in both seasons.The highest means of biological yield were detected for Banei Sweif 6 , followed by Gemmeiza 9, while Gemmeiza-10 recorded the lowest values for biological yield in both seasons.
