Manganese deficiency — Maize

Symptoms

Characteristic symptom: Interveinal chlorosis with pale or white flecks Plants may become stunted, with short, thin stems. Symptoms appear first on younger leaves. Leaves become pale green and develop yellow discolouration between the veins. The veins remain relatively green and prominent. In severe cases, small white or pale flecks develop within the yellow interveinal areas. Leaf tissue may become extensively pale yellow as the deficiency progresses. Ears and kernels may remain small, reducing grain yield.
