Abstract
This study aimed to investigate the impact of which can ¬ optimal delay in sowing date on yield, yield components and agronomic traits in wheat crops in the Khuzestan region 2010-2011 to create a split -plot design in the form of randomized complete blocks design with three replications hub. In the experiment of planting date (ninth and tenth) as main plots and cultivars (Chamran dose) were examined as secondary factors. Two factors were not significantly different. All the characters had a very negative impact on planting delays that ultimately caused the loss of 12.72 percent yield was delayed planting conditions. Chamran cultivars, even though the other character shave a lower numeric value was but had the highest grain yield and grain weight, indicating that this figure is higher in quality than the other varieties are.
