Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
At the end of this Lesson, you will be able to answer:
1. What should be the basis for deciding the amount of
manures and fertilizers to chili pepper?
2. What is the recommended rate of organic manures for
chili pepper?
3. What is the nitrogen, phosphorus and potassium
recommendation for chili pepper?
4. When do you apply nitrogen in two doses?
5. What is the method of application of phosphatic
fertilizers?
6. How do you apply recommended dose of potassium?
Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
Prior to the availability of improved varieties and chili
pepper hybrids, very little fertilizers were used with
consequent low chili pepper yields.
With the cultivation of high yielding varieties and
hybrids, fertilizer application is essential to get the yield
potential of these cultivars.
Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
A soil test is the most practical method of
determining fertilizer needs of chili pepper crop.
However, in the absence of soil test results, the
recommended fertilizer application need to be
followed.
Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
For rain fed crop 2-3 tones of Farm Yard Manure (FYM)
need to be applied before last plowing and then properly
incorporated.
For hybrids and high yielding varieties cultivated under
irrigated conditions, the dose of FYM or compost needs
to be doubled i.e. 5-6 tones/acre.
Azospirillum, a biofertilizer, is recommended to at 2
Ib/acre mixed with each of 25 Ib of FYM and soil, and
applied at the final plowing or at transplanting.

Lesson 4: Application of Manures and Fertilizers
Chili pepper responds profitably to a balanced fertilizer
application program.
Soil testing to know about the nutrient availability is
the first step towards balanced fertilizer program that
do not waste fertilizer by applying nutrients that are
already sufficient for the anticipated level of
production.
Balanced fertility program improves water use
efficiency, drought-tolerance, and yield at the lowest
possible cost.
Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
Under dry land conditions with low rainfall 80 to 120
Ib/acre of nitrogen may be adequate for varieties of
low yield potential.
For long-season, high rainfall or irrigated areas may
require 150 to 200 Ib/acre to get higher yields.
Recommended rate of nitrogen is applied in two equal
split doses in light soils. The first application is done
at sowing and the second one 25 to 30 days after
planting.
Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
Soil tests showing low and very low phosphorous (P)
indicate an expected response to phosphorous application,
unless yield potential is restricted by insufficient moisture.
Response has been erratic with medium testing soil and is
unlikely when soil tests are high or very high.
The recommended rate of phosphorus application is 50 Ib
P2O5/acre for rainfed chili pepper and 80 to 200 Ib P2O5
/acre for irrigated chili pepper.
Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
The recommended rate of phosphorus is applied in one
dose, and along with nitrogen fertilizer at the time of
sowing.
Phosphorus has to be applied as side dressing or by
placement below the seed for its efficient utilization of
plants.
Module V: Chili Pepper Plant Nutrition
Lesson 4: Application of Manures and Fertilizers
Soils with medium or above in potassium will not
normally show a yield response to added potassium
fertilizer.
For soils low in potassium (less than 150 Ib/acre), the
recommended rates are 50 Ib/acre of K20 for rainfed chili
pepper and 150 Ib/acre of K20 for irrigated chili pepper.
Like phosphorus, potassium also is applied in one dose
at the time of sowing along with nitrogen fertilizer.

Lesson 4: Application of Manures and Fertilizers
With this, the Lesson 4 on Application of manures and
fertilizers, and also this Module 5 on Chili pepper Plant
Nutrition concludes.
The next Module in this Course deals with the nutrient
deficiency symptoms in chili pepper.
