Abstract :
In order to investigate effect of seed priming and plantig date on yield and yield components of wheat Chamran variety the research in both laboratory and field in Dezful –Safiabad research center in 2014-2015 was conducted. Treatments include priming with salicylic acid in the four levels {control (distilled water), 0.7, 1.2, 1.7 mM} and four levels of planting date (10 December, 20 December, 30 December, 9 January) in the factorial design based on randomized completely design was conducted at research farm of Agriculture Research Center. The results showed that the effect of planting date on yield and its components were significant at the 1% level. Traits in the latest sowing date significantly decreased. Grain yield in the third planting date (10 January) the highest amount (6207.7 kg / ha).The highest biological yield and harvest index the amount of (14155 kg / ha) and (44.03%) in the third planting date were observed, respectively. In general, the traits were significantly decreased in the last planting date. So to achieve the highest yield, at a concentration of 7.0 mM priming and culture of 10 January date is recommended.
