A field experiment was conducted during winter season of 2015 at a farm in Al-Dear district, Alshenana (65km north of Basea), soil was a clay loam, to study the effect of foliar application of iron and potassium fertilization on growth and yield of wheat (Triticum aestivum L.). Foliar application of iron in three concentrations (0, 40, 80 mgFe l-1), and four levels of potassium fertilizer (0, 20, 40, 60 kg.kha-1). Split plot design in randomized complete block design (RCBD) with three replications was adopted.The main plot was Fe and the sub plot was potassium.Wheat cultivar Bohooth 22 was used The result showed that Increase Fe concentrations increased grain yield and biological yield where 80 mg.l-1 Fe produced grain yield of 5.86 m t/ha. Potassium fertilizer increased grain yield and biological yield. 60 kg.kha-1 potassium gave the higest yield 7.01 m t /ha.The interaction between the high Fe and potassium level gave significant effect on most studied paramtey , the (Fe2k3) caused high grain yield and biological yield and protein content which were 7.17m t /ha, 13.70m t /ha and 17.50%, respectively.
