Abstract EN

This experiment was conducted in Lathhouse, Dept.

of Horticulture/Ministry of Agriculture.

during 2017, to study the effect of Iron chelated was sprayed with three concentrations 0(F0), 20(F1), 40(F2) mg.

L and Gibberellin 0(G0), 50(G1), 100(G2) mg.

L-1 on sour orange seedling with three replications in a factorial experiment with RCBD.

The results showed that the treatment of 100 mg.

L-1 (G2) gave the highest values for vegetative and chemical characters of number of leaves, height of plant, stem diameter, N, K, Mg, and C concentrations that are (7 leaves, 81.6 cm, 0.84 cm, 0.89% , 0.74% , 0.81% and 25.59% ) respectively.

The treatment of iron F2 gave highest values in leaves number, stem diameter, N and K concentration that are (63.3 leaves, 0.82 cm, 0.85% , 0.64% ) respectively and the two treatments F1 and F2 gave highest value of Mg that were (0.69, 0.7)% respectively.

The treatment of G2F2 gave highest values of number of leaves, height of plant branchses number, N, K, Mg, and C concentration that were (76.3 leaves, 90 cm, 7 branch, 0.91% , 0.82% , 0.86% and 28.2% ) respectively.

the lowest values of these parameters found in the control treatment (F0, G0, G0F0).
