Causes
Nitrogen deficiency
Yellowing occurs also with sulphur or molybdenum 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
- Improved crop development
- Increased yield
- Improved fruit quality
