Wheat - Growth retardation
Tünetek
Severe N deficiency (right) results in poor yielding caused by a reduction of tiller number as well as diminished stem, ear and seed size.

Nitrogen deficiency (right)
Wheat - Growth retardation
Tünetek
Characteristic symptoms of N deficiency are reduced vigor, smaller leaves and a pale green or yellowish leaf color.
The symptoms first become visible on the old leaves which turn yellow and wither at progressing deficiency.
Extreme N deficiency causes early senescence and diminished ear size.

Sulphur deficiency, low pH and root damage cause similar symptoms.

Wheat - Chlorosis
Tünetek
Characteristic symptoms of N deficiency are reduced vigor, smaller leaves and a pale green or yellowish leaf color.
The symptoms first become visible on the old leaves which turn yellow and wither at progressing deficiency. Necrosis starts on the leaf tip and progresses toward the leaf base.
Extreme N deficiency causes early senescence and diminished ear size.

Sulphur deficiency, low pH and root damage cause similar symptoms.
Symptoms of N and S deficiency in wheat and other small grains are very similar, thus a tissue analysis is often necessary to reveal the cause.

Nitrogen deficiency vs. optimum a helyzetet tovább rontja
- 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
Nitrogén fontos
- Lusher, greener growth
- Optimal tiller production
- Increased grain yields and protein content
- Improved grain quality

Cereals: 10 to 20 l/ha from tillering to the end of the milk development stage in grain ripening (Zadoks G.S. 21 to 79). Repeat applications at 10 to 14 day intervals. Water rate: 200 l/ha. N.B. Note that later foliar nitrogen applications may raise grain nitrogen status.
