In order to study the effects of iron nano chelatedfertilizers foliar application on yield and yield components of new line ofwheat cold region of Kermanshah provence this study was conducted for one year (2012) in the cold climate of Kermanshah. Experiment wasconducted as a split plot in a randomized complete block design with three replications. Factors studied were at three levels of foliar (a1= at Tillering, a2= the heading, a3= no spray (control)) and the figure of six was (b1= C-87-11, b2=C-87-12, b3= C-87-13, b4=Mihan، b5= Zare and b6= Urom),respectively.Spraying time as the main factor in the main plots and cultivars as sub plots were placed in the subplots. In this study plant height, spikenumber, 1000 grain weight, grain number per spike, biological yield, grainyield and harvest index of wheat were evaluated. Resultsshowed that effect of iron nano chelate foliar application, wheat cultivars andinteraction of them had significant effects on Plant height, spike number, 1000grain weight, Grain number per spike, biological yield, grain yield andharvest index (p≤0.01 and p≤0.05). The highest grain yield,biological yield andharvest index of treatment a1b5 (sprayed at tillering varieties, and still) are respectively the mean 4668/6 kg per hectare, 9769/3 kg per hectare and 65/53% and the lowest it belonged to a3b3 (control (no spray) and line C-87-11),respectively, with the mean 2983/6 kg per hectare, 8723 kg per hectare and 39/66 percent.
