Carrots can grow in a range of soils but prefer deep, well-drained sandy loams or medium loams with a pH of 6-6.8. Land is prepared with raised beds and manure is incorporated before varieties like Up-Country, Low Country, and Nantes are sown 1cm deep in rows 25-30cm apart. Carrots are irrigated daily until germination and then every 4 days, and require fertilizer, weeding, and control of pests like nematodes and diseases like leaf spot. Roots are harvested 75-90 days after sowing when they reach 2.5-4cm in diameter, then graded and stored carefully. Carrots provide health benefits and are

Land preparation
• Soilshould be ploughed to a depth of 30-40 cm and worked
to a very fine tilth
• Prepare raised bed 1m wide and 20 cm high
• Incorporate 5- 10 tons/ha of cattle manure of compost to
beds and level

Sowing
• Seeds maybe sown direct in the field in rows 1 cm deep and
25cm -30cm apart with plants at 5cm intervals in the row
• Seed should be covered with fine soil and pressed down
firmly.
• Seed Rate is 4 kg/ha

Pest and diseases
•Pest
Root knot nematodes (major pest)
Nematodes are microscopic round worms
Feed on plants by puncturing cell wales and
sucking the cell contents.
Damage the growing root tips and result in a forked.

• Symptom -lesions with circular white centers on young leaves.
• Control
• Treating the seeds before sowing with recommended fungicides
• Rotate crops
• Destroy infected plant debris
• Spray foliage with a recommended fungicide.

(03) Bacteria softroot (Erwinia caratovora)
Symptom –
• symptoms are development of soft and gelatinous tissue with a
distinct boundary between infected and healthy tissues.
• Control-
• rotate crop with maize , pulses etc.
• facilitate good drainage
• store root in a ventilated dry place
• fungicide recommendation for disease control

harvesting
• Harvesting iscarried out when the roots attain a diameter of 2.5cm to
4cm at the upper end.
• The normal time of maturity is 75-90 days from sowing.
• When grown on ridges, the roots are pulled complete with tops.
After irrigation or offer loosening the soil with a spade.
• After harvesting ,grade and handle the root carefully, avoiding the
mechanical damage.
• Average yield- Up country – 35-40 tones/ha ,Mid country – 15-
20to/ha
