This experiment studied the response of corn to iron fertilizer in a calcareous soil, Takhli series, which was high in pH and low content of available iron. The investigation was performed in a greenhouse, using Factorial in completely randomized design with 3 replications. Two factors, types of iron fertilizer which were Fe(NH4)2(SO4)2. 6H2O and FeEDDHA and application rates which were 5 ,15 and 45 mg Fe /1 kg soil were investigated. The control treatment was without iron fertilizer application giving the total 7 treatment combination. The results showed that application of iron fertilizer in the form of Fe(NH4)2(SO4)2.6H2O and FeEDDHA significantly increased growth and yield of corn over the control. The effectives of Fe(NH4)2(SO4)2.6H2O and FeEDDHA in the increase of growth and yield of corn were similar. Application of iron fertilizer to corn grown on a calcareous soil, Takhli series is recommended
