Nutrient Disorder Management in Chickpea

Iron >  Zinc > Manganese > Sulphur

Iron Deficiency

Symptoms
  • Newly emerged leaves gets shiny yellowness.
  • Plants get stunted.
  • If severe deficiency of iron persists then the leaves turn brown and then finally get dried up.

Remedies
  • Apply ferrous sulphate (FeSO4) @ 3.00 kg in 600 ml of Teepol and then mix it in 600 litre of water and spray it in 1.00 hectare.

Resources
  • IRON CONTENT OF VARIOUS FERTILIZERS (%)
    Ferrous Sulphate 20%
    Iron Chelate NA.FeEDTA 12%

Zinc Deficiency

Symptoms
  • The symptoms of zinc deficiency include yellowing of upper one third part of the leaflets of middle leaves turn light yellow colour.
  • Gradually turn pinkish/reddish brown.
  • Bronzing and necrosis is observed.
  • Leaflet size decreases.
  • Plants are stunted have fewer branches.

Remedies
  • The deficiency can be rectified by applying zinc sulphate or zinc oxide to the foliage or soil.
  • Apply 25 kg zinc sulphate in light soils once in 5 years.
  • Apply 50 kg zinc sulphate in heavy soils once in 5 years.

Resources
  • ZINC CONTENT OF VARIOUS FERTILIZERS (%)
    Zinc Sulphate 22 - 35%
    Zinc Chelate NaZnGHEDTA 09%

 Manganese Deficiency

Symptoms
  • Symptoms of manganese deficiency develop six weeks after germination in deficient soils.
  • Symptoms comprise chlorosis on the apical margin of leaflets and some curling inwards.
  • The size of leaves is also reduced and young leaves may develop purplish discoloration.
  • Soon after the deficiency symptoms are seen, the terminal growth shows severe withering and necrosis.

Remedies
  • Application of manganese containing fertilizers like:
    Manganese sulphate @ 5 - 15 kg/ha.

Resources
  • MANGANESE CONTENT OF VARIOUS FERTILIZERS (%)
    Manganese Sulphate 23%
    Manganese polyflancohoid 5 - 7%

Sulphur Deficiency

Symptoms
  • Symptoms of sulphur deficiency are seen when grown in high pH calcareous soils.

Remedies
  • Use single super phosphate.
  • Sulphur deficiency can be remedied by the addition of 10 kg elemental sulphur per hectare in sandy loan soils.
  • This increase uptake of nitrogen and phosphorus and the seed yield of chickpea.
