This study was conducted during growing season of 2014 at Girdarash

filed College of Agriculture, University of Salahaddin, Erbil, Iraqi

Kurdistan Region to investigate the effect of foliar spray of three

concentrations (0, 30and 60 mg.l-1) of iron as iron chelate (Fe –

EDDHA) containing (6% of iron) and three concentrations of

Kakrorich (20% nitrogen) foliar spray with concentration (0, 3, 6

mg.l-1) on growth characteristics of pistachio (Pistacia vera L.) cv.

Musilly seedlings. A factorial experiment with three replicates was

carried out in a Randomized Complete Block Design (R.C.B.D) using

three seedlings for each experimental unit. The obtained results

indicated that the growth characteristics increased with increasing the

concentration of (Fe – EDDHA) and nitrogen as compared with

control, foliar spray of iron element at (60 mgl-1) caused significant

increase in seedling hight, seedling diameter, leaves number, leaf area,

leaves area/seedling, total chlorophyll content, root length, root fresh

weight, root dry weight and dry matter percentage. At the same time,

application of nitrogen fertilization at (6 mg.l-1) gave the highest value

of seedling high, leaf area, leaves area/seedling, root fresh weight. The

highest significant values as interaction effect of iron chelate and

nitrogen were found in seedling high, seedling diameter, leaves

number, leaf area, leaf area per seedling, total chlorophyll content and

dry matter.
