Symptoms
                                Plant shows stunted growth. At severe deficiency necrotic zones develop at leaf margins and tips.
                            
                                Reasons
                                Severe iron deficiency (left)

                                Symptoms of iron deficiency start on younger leaves. Plants show chlorotic leaves with interveinal stripes. When the deficiency becomes severe the veins also become chlorotic and plant growth is stunted.
                            
                                Reasons
                                Iron deficiency 
Can be confused with manganese deficiency, but manganese deficiency is very rare in corn.
Magnesium deficient plants also show interveinal chlorosis, but the symptoms start on older leaves.
