ield experiment was carried out in a loamy sand soil mixture, at Al-Naemea region, Fallujah City of Al–Anbar province, during the spring and autumn seasons of 2013, to study the effect of three plant spacing between plants10, 15 and 20 cm and four concentrations of foliar feeding of iron 0, 50, 75and100 mg Fe L-1 in growth and yield of maize Ipa 5018. Factorial arrangement was use with R.C.B.D.in three replicates. The results showed that a distance of 10 cm of planting gave the highest mean for each of the plant height, leaf area index and total grain yield 4.75 and 6.15 t ha-1 for two seasons respectively. While the distance of 20 cm planting gave the highest mean for each of the leaf area in autumn season, ear number per plant, number of rows per ear and weight of 500 grain for two season respectively. The concentration 100 mg Fe L-1 gave the highest mean for each of the leaf area ,leaf area index, ear number per plant, number of rows per ear, weight of 500 grain and total grain yield 4.82 and 6.38 t ha-1 for two season respectively. While the concentration 75 mg Fe L-1 gave the highest mean of plant height. The interaction between planting distance of 20 cm and a concentration of 100 mg Fe L-1 was significant effect in ear number per plant and number of rows per ear in autumn season and leaf area and weight of 500 grain in both season respectively. While the interaction between 10 cm distance with concentration 75 mg Fe L-1 significant effect in leaf area index and total grain yield in both season respectively.

A field experiment was conducted to study the effect of chelated Iron fertilizers produced from the reaction of Humic and Humic +Fulvic extracted from corn cubs and wheat straw with Iron sulphate added as Iron Humate (Fe-HAz) and Humate and fulvat Iron (Fe – HA +FAz ) extracted from corn cubs, Iron Humat (Fe –HAw ) ,Iron humat and fulvat (Fe–HA+FAw) extracted from wheat straw. Iron was also added as Fe–DTPA and FeSO4.7H2O. All sources were sprayed on the green part (A1 ) at a level of 2 Kg Fe.ha-1 and 10 kgFe.ha-1 when added to soil (A2) and half these amount added to green part and to soil (A3).
Results showed that sources of Iron has significantly increasing cucumber yield .Fe-HA+FAz was out starting in the total yield, number of fruits and Phosphorus and Iron content. in leaves with the an increase of 33.69%, 36.32%, 30.59% and 145.81% respectively compared to control. mineral Iron source (FeSO4.7H2O) has achieved an increase of 18.73%, 9.90%, 11.90% and 57.55% of the parameters respectively compared to control. Fe-HA+FA extracted from wheat straw has achieved highest content of N and K in leaves with an increase of 61.23% and 114.08 % in comparison with the control treatment
