Introduction
• A true biennial• Producing thickened root and a rosette of leaves• Mainly grown for their swollen roots • The cultivation of beetroot is not limited to the hill
country • Now being successfully carried out in the Puttalam
District• Beetroot is an excellent source of folate and a good
source of manganese, and contains betaines .

• Beetroot is a cool-season crop
• Fairly tolerant to high temperatures
- with adequate soil moisture provided
• Excessively hot weather :
- alternating light and dark red concentric circles
- in the root zoning
• Very cold weather results slow or no growth of the
plant
![Page 8: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/8.jpg)
Rainfall
- Beetroot needs a lot of water for fast growth- The volume needed could vary from:
* 2 mm on a cold winter day * 8 mm on a hot summer day
![Page 9: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/9.jpg)
Soil
Soil required - Deep well drained - loose
- sandy loamy soils - with a high organic content
• Soil pH beetroot prefer: range between 6.3 and 7- Acid soils create nutrient deficiency problems - should be avoided or limed to raise the pH
• Salinity Tolerance- Mature beets fairly tolerant - Seedlings relatively sensitive

Land preparation and Establishment
• Nursery- Soil worked to a fine tilth
- Prepare raised beds Width: 1m
Height: 20cm
• Field- Soil should be ploughed to a depth of 20-30 cm
- worked to a very fine tilth - Apply 10 -20 t/ha of organic matter
![Page 13: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/13.jpg)
Planting• Nursery- Seed can be broadcast or row – sown
• Field - Up -country : healthy 3-4 week old seedlings
transplanted on raised beds
- Low lands : Transplant seedlings on ridges or raised beds
- 30 cm between rows - 10 cm within the rows
Spacing

Irrigation
• Should be kept moist to a depth of 20 to 25 cm• Plantings should receive light water applications
daily until the young seedlings come up• About 30 mm of water should be supplied per
irrigation• Large fluctuations in soil moisture content will
result in poor quality roots-malformed and have many small hairs or
side roots

Weed control
• Controlled before they can compete with beet seedlings and interfere with their growth– Hand weeding– Chemical application
![Page 19: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/19.jpg)
Pest & Diseases
PestsAphids (Aphis fabae) - Dark brown or green insects - About 2 mm in length - Suck on the lower surface of the leaves Infested leaves are curly and rolled
Use registered chemicals. Crop rotation can also assist
![Page 20: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/20.jpg)
Red spider (Tetranychus cinnabarinus) - Small dark red or dark brown spiders - About 1 mm long- Suck on the lower surface of the leaves- Numbers can increase rapidly during warm
weather
![Page 21: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/21.jpg)
Leaf-eating insects -Leaves are mainly eaten in summer
![Page 22: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/22.jpg)
Diseases
Cercospora leaf spot (Cercospora beticola) -Caused by a fungus-Enters the leaves and causes small round spots
of about 3 mm in diameter -Spots first brown with a dark purple border later turn grey in the center
![Page 23: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/23.jpg)
Downy mildew (Peronospora schachtii) - Seed-borne disease- Can affect the crop early in the season- Leaves of infected plants partly or completely
turn yellow and curl downwards- Flowers and the crown can also be infected
![Page 24: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/24.jpg)
Other diseases: • Brown rust (Uromyces betae)• Scab (Actinomyces scabies)• Root rot, damping-off (Phoma betae)
![Page 25: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/25.jpg)
Other cultivation practices• Thinning- Carried out when the seedlings are still small - About 5 to 7 cm apart in the rows - If plant emergence is good
• Seed treatment- Washed in running water for at least 2 hours- Soaked in a 0.5 % Aretan solution for 20 minutes after
washing - Dried for at least 6 hours at room temperature before
sowing
![Page 26: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/26.jpg)
![Page 27: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/27.jpg)
Harvesting
• Harvest maturity - Usually harvested when the roots reach
3 - 5 cm in diameter-Harvested 6-8 weeks after planting
![Page 28: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/28.jpg)
• Harvesting methods
- Lifted by hand or mechanically when grown on a large scale
- Lifts the crop from the soil and cuts off the leaves
- Care should be taken in pulling roots from the soil and in their handling
![Page 29: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/29.jpg)
Post-harvest handling
• Sorting and grading- All diseased roots and those showing
mechanical injury are removed- Old, dead or damaged leaves should be
removed if the crop is to be marketed with tops
- Graded according to size
![Page 30: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/30.jpg)
• PackingAfter washing, the crop is packed in crates or cartons and kept in a cool and dry environment
• StorageThe environment must be dry
-to avoid fungal attackThe temperature must be kept at 0 °C and the relative humidity at 90 %
![Page 31: Beet root](https://reader036.vdocuments.site/reader036/viewer/2022081603/55891327d8b42a0b258b4715/html5/thumbnails/31.jpg)
• Transport-Should be transported in a well ventilated vehicle and at cool temperatures
to avoid fungal infestation
-The temperatures should never go below 0 °C because the crop will experience cold-wilting
• Marketing– Cost of Production
Major portion of the cost of production accounts for fertilizer (38%) and labour (39%). For pesticides :9%
