Nitrogen deficiency

Oil Palm - Chlorosis

Oil Palm - Growth retardation

Symptoms

Reasons
Nitrogen deficiency

Nitrogen deficiency made worse by

  • Low or high pH soils
  • Sandy or light soils (leaching
  • ) Low organic matter
  • Drought conditions
  • High rainfall (leaching) or heavy irrigation
  • Addition or high levels of non-decomposed organic matter/manure (eg straw)
  • Fast growing crops

Nitrogen is important for

  • "Promotes growth and net assimilation rate
  • Increases leaf area and leaf production, which is one factor of high yield
  • Increases fruit bunch and total oil yield
  • "
