Calcium deficiency — Maize

Symptoms

Characteristic symptom: Deformed, torn and tightly rolled young leaves Plants become stunted, with short, thick stems. Symptoms appear first on the youngest, emerging leaves; older leaves may remain dark green and relatively healthy. Young leaves develop pale green areas followed by yellow or white lesions between the veins. The leaf blade becomes malformed, torn or ragged. Affected young leaves may remain rolled, and their tips may stick together instead of separating normally. In severe cases, newly emerging leaf tips remain joined together, producing a ladder-like appearance in the whorl. Under acute deficiency, the youngest leaves may die.
