Abstract

This study was designed to investigate the impact on the amount of damages for the delay in sowing of wheat yield and in fluences Wheat stripe rust pathogen in agricultural province in northern climates 90- 1389 split plot in a randomized complete block design with three replications in the experiment of planting date (ninth and tenth) asmain plots and cultivars as sub plots were examined. The results showed that there was significant effect of planting date on all traits that will ultimately lead toa significant reduction in all traits (yield, fertility rate, tiller, tiller number per plant and plant height) were delayed in planting, one of the main reasons for there cent results can beincreased by 25% in plant sin fected with yellow rust of wheat from 45 percent to 70 percent. Chamran cultivars in the first planting on average 3/3733 kg ha had thehighest yield.

Keywords: rust, planting dates, varieties, yield, yield components.
