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.
