Calcium deficiency Symptoms in Tomato plant

  • Symptoms are primarily visible in the rapidly growing areas because of the very low mobility of calcium in plant tissues.
  • Calcium-deficient leaves show chlorosis and then necrosis around the base of the leaves. 
  • The plants become flaccid; dead spots appeared on the upper stems and the growing apex died.
  • Upper leaf coloration initially was a darker green, but, later turning yellow at the edges and died. 
  • Fruits showing blossom end rot were found to ripen less rapidly. Blossom end rot is closely associated with Ca deficiency of the fruit.
