Phosphorus deficiency
Pepper - Chlorosis

Phosphorus deficiency
Pepper - Chlorosis
Symptoms
The leaf blade has got a mottled, partly chlorotic and partly dark green appearance.
Causes
Phosphorus deficiency
Pepper - Discolouration
Symptoms
Fruit on P deficient plants are often shorter and narrower than normal
Causes
Phosphorus deficiency on fruit
Phosphorus deficiency vs. optimum made worse by
- Acidic or very alkaline (calcareaus) soils
- Low organic matter
- Cold or wet conditions
- Crops with a poorly developed root system
- Soils with low P reserves
- Soils with a high phosphate capacity
- Iron rich soils
Phosphorus is important for
- Ensuring good start and continued growth for high yield
- Increases fruit set, fruit development and early maturity
