Effect of levels of N and foliar application of Fe on N and Fe concentration in soil and plant

A field experiment was carried out in Al-Muthanna province, southern Iraq, 2015 to study the effect of nitrogen in four levels (0, 60, 180, 240) kg N ha^-1 and foliar application of  iron (0,50,100,150) mg Fe l ^-1 on growth and yield of wheat Al- Rashid variety. Split plot design of two factors was used in this study, nitrogen the main plot and iron was the sub plot. N3 treatment significantly excelled N₂ in the plant height 109.2 cm and leaf area of ​​45.59 cm ² and weight of a 1000 grain 51.95 g  and  the N content of plant  2.75{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d} and N available in soil at flowering stage 32.31 mg N Kg ^-1 soil dry. the N₃ level gave highest values of Iron concentration in plant 98.12 mg Fe reached Kg ^-1 dry matter and Fe available in the soil at flowering stage 3.35 mg Fe Kg ^-1 soil, as compared to the control. Iron F₃ treatment showed the highest leaf area 47.53 cm ²   and N concentration in plant 2.72{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d} and the iron concentration in plant 93.41 mg Fe Kg ^-1 dry matter and the nitrogen available and available-iron ratios in the soil at flowering , the F₂ level was superior for  plant height was 107.3 cm, as compared to check. N₃F₃ treatment was superior over all, particularly control
