Abstract

An experiment was conducted to study the effect of iron (Fe) applied at
different rates of 5 ppm (Fe), , 10 ppm (Fe)2 and 20 ppm (Fe) J as well as nickel
applied at the rates of 2.5 ppm (Ni) , , 5 ppm (Nil 2 and 10 ppm (Ni) J along with their
combinations of 5 ppm Ni +5 ppm Fe(NFC) 1,5 ppm Ni +10 ppm Fe(NFC)2, 5 ppm Ni
+15 ppm Fe(NFC} J and 5 ppm Ni +20 ppm Fe(NFC4} on plant growth ,nutrient
uptake and certain metabolic parameters of two com varieties (Giza 10 and Giza
122). The different applications of both Fe and Ni significantly increased the dry
matter production of shoot ,root and shoot Iroot ratio along with nutrient accumulation
in the two studied corn varieties at low both and moderate concerned rates. Applying
high rates caused adverse effects compared to the control. In leaves, chlorophyll content generally was increased with applied Fe and
law rates of Ni, such response being dependent on the concerned variety .
Furthermore, these metals induced leaf accumulation of total soluble sugars
(TSS),reducing sugars (RS) and non reducing sugars (NRD) at moderate rate of both
Fe , Ni and their combinations. Data suggest that application of moderate rate of Fe
and low rate of nickel, either applied separately or combined together, was most'
suitable for plant growth.
