Abstract EN

This study was conducted during 2012/2013 and 2013/2014 seasons in the Agricultural Research Station of king Abdulaziz University at Hada Al-Sham to study the effects of 4 rates of olive byproducts, and 3 chelated iron rates on Giza 123 barley cultivar.

The study was carried out in a split plot design in 4 replicates.

The main obtained results showed that the rate of 15 t/ha olive by – product significantly dominated over the different rates and produced 3.956 and 9.844 t/ha of grain and straw, respectively.

The rate of 10 kg chelated iron significantly increased grain and straw barley yields compared with 0.00 chelated iron but no significant difference was detected from the effect 15kg chelated iron /ha, on grain or straw yields/ha
