Abstract

To study the effect of spraying concentrations of Iron and Zinc on some yield components of two varieties of wheat ( Ipa 99 and Dor 29). Factoral Field experiment was conducted at Field of crop production Sciences, College of Agriculture – university of Baghdad, at silty clay loam soil. Requirements of N, P and K fertilizers were added. Concentrations of Fe ( 0, 50 and 100) mgFe.L-1 and ( 0, 50 and 100) mgZn.L-1 were sprayed at three stages of plant growth ( vegetative growth, boating and flowering stages). Randomized complete block design was used at three replicates. Results showed that: All concentrations of iron and zinc were significantly increased all studied , weight of 1000 grain, biological yield 1-parameters which were number of grain.spikeed high of those parameters of Ipa produc 2Zn2and grain yield.
