Oil Palm - Chlorosis

Symptoms
At the beginning, interveinal chlorosis is observed on the leaflets of the youngest fronds. It proceeds from the leaf tip towards the leaf base. At a later stage, the whole frond becomes pale green or white and chlorosis expands to lower fronds, too.

Reasons
Iron deficiency Fe deficiency is very rare in oil palm grown on acid tropical soils.

Iron deficiency made worse by

  • High pH
  • Water logged soils
  • Calcareous soils
  • High copper, manganese or zinc soils

Iron is important for

  • Essential for catalyzation of redox processes, photosynthesis, energy metabolism and N2 fixation
  • Part of iron-sulphur proteins
  • Needed for proper growth of well-formed and healthy green leaves
