Lesson 3: Ratoon Cropping
Ratoon cropping is the technique of allowing a crop to
produce two crops of yield from one planting.
The principles involved in ratoon cropping are that the ratoon
crop has well developed root system, earlier maturity, and the
perennial nature.

Lesson 3: Ratoon Cropping
The advantages of ratoon cropping are:
• Reduced cost of production through savings
in land preparation and care for the plant;
• Reduced crop cycle: crop planted less often,
so replanting cycle is longer;
• Better use of growing season;

Lesson 3: Ratoon Cropping
The advantages of ratoon cropping are:
•
•
Higher yield per unit area in a given period
of time;
Less use of irrigation water and fertilizer
than main (original) crop because of a
shorter growing period.

Lesson 3: Ratoon Cropping
Recently, the ratooning of kharif chili pepper is becoming
popular.
Ratooning of kharif chili pepper becomes successful if
little care is taken at the time of harvest of original crop of
chili pepper.
With adequate rainfall, a second crop of grain (usually 40
to 50 percent less than the yield potential of the planted
crop) may be produced. It is likely that insect pressure will
be heavy on this second crop.

Lesson 3: Ratoon Cropping
For taking ratoon crop of chili pepper:
Main crop should not be cut above the ground level after
its maturity. Harvest all fruits and left the plant for next
crop.
The field need to be cleaned by removing diseased and
damaged plants, weeds and dried leaves etc. This should
be completed within 4-5 days after harvest of the main
crop.

Mix in the soil 25 Ib N and 20-25 Ib P2O5/acre using a
blade hoe in between two lines.
The crop should be irrigated immediately after the
application of fertilizers, if there are no rains.
Spray 0.04% Endosulphan 35 EC seven days after the
harvest of main crop to control shoot fly.

Lesson 3: Ratoon Cropping
Harvest the crop when the grains turn yellow.
The duration of the ratoon crop is about 15 days
less than the main crop.
The yield of ratoon chili pepper could be about
1500-2000 Ib/acre depending upon the variety,
soil type and management of the crop.
