Abstract

A pot experiment was carried out to study the influence of irriga­tion intervals, N-and Fe-fertilization on uptake of some macro - and mi­cro nutrients by wheat plants grown on alluvial and calcareous soils. The obtained results could be summarized in the following-- N and P-uptake were significantly affected by irrigation intervals. the highest values were found in the 8 days interval treatments In­creasing N and Fe fertilization levels led to pronounced increases in N­and P-uptake in alluvial soil. Zn, Fe, Cu and Mn uptake were significantly affected by soil type. Increasing N fertilizer levels and decreasing irrigation intervals led to in­creases in the micronutrients uptake . However, increasing Fe fertiliza­tion resulted in increases in Zn and Fe uptake and decreases in Mn and Cu uptake by wheat plants.
