1. Under what conditions nitrogen deficiency results in
chili pepper?
2. Describe the leaf symptoms due to nitrogen deficiency
in chili pepper?
3. Why nitrogen deficiency symptoms are prominent only
in older leaves?
4. How the chili pepper plants look in a nitrogen deficient
field?

Lesson 2: Deficiency Symptoms of Primary Nutrients
Unit 1: Nitrogen Deficiency Symptoms
Nitrogen deficiency generally results from inadequate
fertilizer application, or leaching loss due to excessive
rainfall.
Leaching occurs most commonly in sandy-textured plain
soils during periods of excessive rainfall.
Nitrogen is also lost through volatilization from surface
applications during periods of hot, dry weather.

Lesson 2: Deficiency Symptoms of Primary Nutrients
Unit 1: Nitrogen Deficiency Symptoms
Nitrogen deficient plants are
stunted, pale green to pale yellow,
and grow more slowly Fig.).
Eventually, the affected leaves
become brownish, wither, die and
hang down around the lower stem.

Lesson 2: Deficiency Symptoms of Primary Nutrients
Unit 1: Nitrogen Deficiency Symptoms
Yellowing or chlorosis appears
first on the lower leaves; the upper
leaves remain green.
The tendency of the young upper
leaves remaining green is due to
nitrogen moving towards the newly
growing leaves.
Note the pale green,
yellow, and brown
lower leaves.

Lesson 2: Deficiency Symptoms of Primary Nutrients
Unit 1: Nitrogen Deficiency Symptoms
The plants will be stunted in growth
and with thinner stems.
Greater red streaking can be seen on
the lower leaf sheaths of the nitrogen
deficient plant.

Lesson 2: Deficiency Symptoms of Primary Nutrients
Unit 1: Nitrogen Deficiency Symptoms
Flowering of chili pepper plants
is delayed due to nitrogen
deficiency.
Plants on right have received no
nitrogen fertilizer and show
delayed flowering.

With this, the Unit 1 on Nitrogen Deficiency Symptoms in
this Lesson concludes.
The next Unit in this Lesson is about phosphorus
deficiency symptoms in chili pepper.
The last Unit in this Lesson deal with potassium
deficiency symptoms in sorghum.
