Intensive agriculture, cultivation of high yielding varieties and extensive use of chemical fertilizers in unbalance manner have created deficiency of certain major plant nutrients in the soil. Calcium is one of the most critical secondary nutrients that are vital for the growth and strength of the plants body. Its deficiency may cause heavy losses both qualitatively and quantitatively.

Lack of Calcium produces a general breakdown of cell membrane structures with resultant loss in retention of cellular diffusible compounds. Calcium enhances uptake of NO3 –N and therefore is interrelated with Nitrogen metabolism. Calcium is essential for cell elongation and division thus plays important role in the growth of terminal buds of shoot and apical tips of roots. Calcium plays important role in development and storage (shelf life) of certain vegetables and fruits like potato, Tomato, cauliflower, chili, Peas, Apples, and Banana etc.

Importance of Calcium in plants

  • Calcium plays an important role in maintaining physical strength of the external organs.
  • Makes the plants capable of holding and bearing weight of seeds and fruits.
  • Maintains strength and permeability of cell walls.
  • Calcium enhances the uptake of Nitrogen, thus promotes vegetative growth.
  • Essential for cell elongation and cell division.

Symptoms of Deficiency

Young leaves are affected first and become small and distorted or chlorotic with irregular margins, spotting or necrotic areas. Bud development is inhibited, blossom end rot and internal decay may also occur and root may be under developed or die back. Deficiency will cause root tip die-back, leaf tip curl and marginal necrosis and chlorosis primarily in younger leaves. Leaves develop chlorosis and distortion such as crinkling, dwarfing, developing a strap-like shape, shoots stop growing and thicken.

Deficiency symptoms as appeared on the leaves of Okra (Lady’s Finger) and cabbage. In some plants, the older, larger leaves just above the bottommost ones will show the first symptoms.

Development of Deficiency

The symptoms often appear quickly; within one or two weeks of the first spots being visible on the tender leaves. The spots usually start as small, light brown specks that increase in size over time.

  • After two weeks, the older leaves show ever increasing spots and the spots also often appears at the edge of the leaves, as with potassium deficiency or with scorch symptoms.
  • The spots have a sharp outline and do not originate exclusively at the edge of the leaves. A lag in development is often already noticeable within a week.
  • Sometimes the growing points will wrinkle up and around the fruits and farmers find thin, small leaves that are not spotted.
  • The older leaves die off slowly and yellowish cloudy spots may appear around the necrotic spots. The older the leaf is, the more serious the symptoms are.
  • The flowering is also hindered and slowed down. Fruits and grains stay small resulting huge loss of yield.
