Abstract
A field experiment was conducted to determine the effect of two planting dates ; early (25th Oct.) and late (15th Dec.) in addition to the control planted at 20th Nov. on phenology, growth, yield ( yield components and yield quality) of four bread wheat (Triticum aestivum L.) cultivars ; Sakha 93, Sakha 94 ,Gemmeiza 9 and Giza 168 at Sakha Agricultural Research Station. In general, the obtained data showed that, the requirement of days and Growing degree days (GDD) to attain different phenological stages (seedling, booting, heading, anthesis and maturity) decreased with delay in sowing date . Also, planting on the control date (20th Nov.) surpassed the other sowing dates in all yield studied parameters and flour quality. However , late sowing date (15th Dec.) caused an increase in most technological properties ( protein , wet and dry gluten) of the yielded grains .
