Nitrogen deficiency vs. optimum-Oats

Symptoms
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.

Reasons
Nitrogen deficiency (left) Sulphur deficiency, low pH and root damage cause similar symptoms.

Symptoms
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.

Reasons
Nitrogen deficiency(bottom) 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.

Symptoms
Severe N deficiency (left) results in poor yielding caused by a reduction of tiller number as well as diminished stem, ear and seed size.

Reasons
Nitrogen deficiency (left)

Symptoms
Starting on the older leaves, N deficiency causes chlorotic yellowing and stunted growth of cereal plants.

Reasons
Nitrogen deficiency Symptoms of N and S deficiency in cereals are very similar, thus a tissue analysis is often necessary to reveal the cause.

Symptoms
Starting on the older leaves, N deficiency causes chlorotic yellowing and stunted growth of cereal plants. Tillering and ear size are reduced. Severe lack of N leads to early senescence.

Reasons
Nitrogen deficiency (right) Small grains are generally sensitive to insufficient N Symptoms of N and S deficiency in cereals are very similar, thus a tissue analysis is often necessary to reveal the cause.
