Importance of Zinc in plants

  • Plays important role in protein synthesis and production of Auxin.
  • Regulates vegetative growth as promoter.
  • Regulates level of Phosphate within the plant body.
  • Essential for synthesis and activation of various enzymes and growth hormones.
  • Activates many metabolic activities.
  • Develops resistance against environmental stress and pathogens.
  • Ensures timely maturity of the plants.

Symptoms of Deficiency

Zinc deficiency can often be identified by distinctive visual symptoms that appear most frequently on the leaves. Sometimes the symptoms also appear on the fruits and branches and evident in the overall development of the plant. The common symptoms are as under -

  • Occurrence of light green, yellow or white areas between the veins of leaves, particularly the older   lower leaves.
  • The above spots turn into brown to chlorotic patches resulting death of tissues.
  • Shortening of stem or stalk internodes resulting a bushy, rosetted appearance.
  • Small, narrow, thickened and malformed leaves.
  • Less or no flowering, less fruit or grain setting.
  • Early loss of foliage can cause complete damage to the crop.
  • Malformation of fruits or grains often with less or no yield.

The net results of Zinc deficiency are stunted growth, yellowing and chlorosis with brown spots on the green parts of the plants, prolonged maturity and poor yield. A severe deficiency may kill the entire crop.
