Abstract
Abstract : A Field experiment was conducted at the farm of Al- mhnawiah region in Babylon government on 2012 – 2013 season according to ( RCBD ) design included two spray times , using 13% Fe - EDTA Chelated as ferrous ( iron ) source and %15 Zn - EDTA Chelated as zinc source to know the effects of these two elements as foliar application on plant content of some macro - and micro - elements , the iron element significantly increased N , P , K and Ca elements giving 113.3% , 55% , 28 % and 49 % respectively , Concerning zinc element effect , it caused an increase of N element reach as maximum to 140 % and there was no remarked changes in P element but it increment effects on K and Ca elements . Concerning micro - elements , it's appeared that the iron element caused a significant increase of Fe element reached as maximum to 17.9 % and 51 % in leaves and seeds content respectively . The same trend was found with Zinc element on leaves too , but reached to 26.5 % and there was no remarked changes of the seeds content of Zn element .
