Module V: Chili Pepper Plant Nutrition
Lesson 1: Importance of Chili Pepper Nutrition
After completing this Lesson, you would be able to answer:
1.
Why application of manures and fertilizers is important in
chili pepper cultivation?
2.
How the gap between actual and potential chili pepper yields
could be reduced?
4. What is the usual notion (thinking) about phosphorus
application to chili pepper crop?

Lesson 1: Importance of Chili Pepper Nutrition
Common fertility management in chili pepper production often
begins with an initial application of chicken manure (three
to four tons per acre) during soil preparation.
The manure is broadcasted, then disced and floated for
incorporation. A preplant application of chemical fertilizers
(e.g. 1000 lbs. per acre of 11-52-0) may be substituted for
the chicken manure. The fertilizer is broadcasted flat and
listed into the beds.

Nitrogen (N) sources such as neutral 8-8-8 (used in this study), AN
20, liquid UAN 32, or CAN 17 may be used to supply an additional
120 to 200 pounds of N per acre.
This brings the total annually applied N and Phosphorus to about
300 pounds per acre.
Application of about 10 to 15 pounds of N per acre per week is
recommended. Contact your crop consultant for information about
in-season leaf petiole and blade nutrient assessment.

Lesson 1: Importance of Chili Pepper Nutrition
The high yields in chili pepper is
generally due to the crop being
grown under favorable
conditions like loamy soils, often
rainfall conditions etc.

Nutrient removal and yield
There is a wide gap between the
national average yield (less than
1000 Ib/acre) and the potential
achievable yield (more than
3,500 Ib/acre).
Inadequate availability of
essential nutrients could be one
of the reasons for such a wide
gap in chili pepper yields.

Lesson 1: Importance of Chili Pepper Nutrition
General thinking is that most of the soils are rich in
phosphorus and so there is no need to apply
phosphorus to chili pepper.
The correctness of this statement has to be verified by
soil testing.
Phosphorus is not needed if levels]of soil phosphorus
are between medium and medium-low, based on the New
Mexico State University analysis system (Guide A-122,
Soil Test Interpretation, Cooperative Extension Service,
New Mexico State University).
