Response of some six rowed barley varieties (Hordeum vulgare L.)‎ to micronutrient Fe for growth and yield under dry farming condition

Abstract 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.
