الملخص EN

This study carried out in Sulaimani region at Bakrajo directorate of agriculture research station during the cultivate season of 2017-2018 to evaluate the response of four barley varieties (Tadmor, Zabad, Legnee and Arivat) to three levels of Fe- EDDHA (0, 20 and 40 kg ha-1), the design of split plot was conducted.

The results of the study confirmed that there were significant differences among genotypes for all studied characters.

The application of 40 kg/ha Fe- EDDHA produced maximum value for almost all studied characters.

The maximum grain yield was 6.333T/ha produced by Lignee variety as 40 kg/ha of Fe- EDDHA was applied.

Maximum positive direct effect in grain yield recorded by biomass yield 1.551, and followed by harvest index and weight of grains/ spike 1.347 and 0.866 g respectively.

This indicates that the increase of these components causes some increase in grain yield.
