AbstractA 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.
