A field experiment was conducted during the winter season of 2013 -2014 at kitaiban district east Basrah province location at (15) km from city center .

The study was conducted to study the effect of three levels of foliar application of Iron at three constructions (0 , 75 , 100) mg.L-1 and three levels of manganese constructions( 0 , 50 , 100) mg.L-1 on growth and yield of wheat (Iba 99) cultivate .

A factorial experiment in used with the Randomized complete Block design in three Blocks.

The results showed that Iron affecting significantly on all yield component and grain yield .

The( Fe2) level gave the highest spike number per square meter , number of grain per spike , grain yield and biological yield with a means (430.8 spike.m-2, 45.22 grain .spike -1 , 4.244 Ton.ha-1 , 9.294 Ton.ha-1) respectively.

The 1000 grain weight was the highest at( Fe1 and Fe2) levels as it was( 28.02 and 27.66 ) g respectively without significant differences between them and with significant differences from the control.

Adding manganese levels to significant increase in the Studied traits of wheat yield component and wheat grain yield .Also The higher level of manganese (Mn2) gave the highest number of spike.m-2 , grain number.spike-1, grain yield and biological yield of with means (412.0 spike.m-2 , 43.91 grain.Spike-1, 4.167 Ton.ha-1 and 8.897 Ton.ha-1) respectively.

Whereas the Mn1 level gave the highest 1000 grain of (27.90) gm The interaction between (Fe2 * Mn2) gave the highest number of spike.m-grain.spike-1, grain yield and biological yield of (481.0 spike.m-2 , 48.80 grain.spike-1 , 4.367 Ton.ha- 1, 10.090 Ton.ha-1) respectively.

The interaction between (Fe1 * Mn1) gave the highest 1000 grain weight of (31.93) gm.
