Abstract
preliminary
 study was carried out in order to investigate the effects of application of
 treated sludge and Fe fertilizer on the yield and Fe content of maize. The
 trial was conducted in randomized plots design with three replications as pot experiment
 and C-955 hybrid maize was grown for silage. As basic fertilization, 200 mg kg-1
 N, 100 mg kg-1 P and 150 mg kg-1 K were applied to
 all of the pots. Treatments were (C) control, (T1) 5 mg kg-1Fe (Fe
 in sludge) + 10 mg kg-1Fe (FeSO4,7H2O), (T2)
 10 mg kg-1 Fe (Fe in sludge) + 5 mg kg-1 Fe (FeSO4,7H2O),
 (T3) 15 mg kg-1 Fe (Fe in sludge) and (T4) 15 mg kg-1 Fe
 (FeSO4,7H2O). Applications of sludge and Fe increased wet
 weight, dry weight, plant height, leaf number and the content of N, K, Fe, Zn
 and Cu of maize plant. It was concluded that application of 15 mg kg-1
 Fe in sludge is sufficient for Fe need of maize. However, the obtained results
 from this study were valid only for this study soil and sewage sludge and
 should be used without generalization as they can vary under different
 conditions such as soil and climate. Therefore, further researches are needed
 on this field.
