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

  • Key role in many growth processes
  • High demand for growth, yield and quality
  • Increases bunch weight, number of hands/bunch
  • Level of dry matter, sugars and TSS/Acid ratio of fruit improved
  • Helps optimizing vitamin C levels in the fruit
  • Germination and development of daughter suckers
