Carrot is belongs to Apiaceae family. It can be grown successfully, in all the agro-ecological zone.
Climate requirements/ Areas suitable for cultivation
Carrot can be grown well in cool area of up country regions. It can be cultivated in all the agro-ecological zones.
It need a finely prepared well drain soil with more organic matter.
4 kg seed /ha
Plough up to depth of 30 cm and finely prepare soil before planning. Seed are plating on one-meter width raised beds.
Row spacing is 25 cm, seedling thinning to 5 cm spacing.
Organic manure 10 t/ha
|Time of application|
|Top dressing (3 weeks after planting)|
|Top dressing (6 weeks after planting)|
|Top dressing (8 weeks after planting)|
|Top dressing (9 weeks after planting)|
Root enlargement stage of carrot is the most critical stage of water. Light, frequent irrigation is required to obtained good yield.
Weed control can be done by manually or chemical method. Pre-emergent herbicide; metribuzin at the rate of 0.35 kg/ha apply before germination seedling.
Become serious pest during the dry period
Adult punchers leave for both feeding and oviposition. This may cause a spotted appearance on foliage. Larvae make irregular mine and result drying and withering of leaves. Damage plants succumb to secondary infection by late blight.
- Regular field inspection
- Yellow colour sticky trap
- Covering crops with suitable material prevent mitigating flies
- Removal of other host plants surrounds the crop field
- Removal and distruction of infected plant material
- Augment ecto-parasitoid Diglyphus isaea
- Encourage naturally found parasitoids Hemiptarsenus semibiclavas and Opius spp
- Azadiractin 1% EC at the rate of 16ml/16 l of water
- Abamectin 18g/l EC at the rate of 9.6 ml/16 l of water
- Neem seed water extract at the rate of 640g/16 l of water
Habitually they are nocturnal. Early instars make round holes in leaves. Later, the shoots are damaged close to the ground, often cut the whole plant at the base, during emergence. Cut several plants in a single night and pulling the plant stem belowground. Cut plants show wilting during day time. Formed unsightly holes in the tubers
- Regular monitoring
- Hand collecting and destroying
- Weed management
- Proper field sanitation
- Plough the soil deeply to bring the larvae and pupa to the surface of the soil
- Encourage predatory birds to preying the worms during tillage operation

Following symptoms may begin as small patches and these may enlarge as the nematode population increase.
- Uneven growth
- When uproot tubers can observed
- Galls on feeder roots
- Forking of the tap root
- Bunching of roots
- Prevent entering
- Avoid moving plants and soil from infested field
- Don’t allow irrigation water from around infested field
- Clean tools thoroughly before using them
- Tilling the soil two or three times and expose to sunlight
- Add poultry manure two weeks before seeding
- Crop rotation
Destroy seedlings at the emergence. Damage is severe during high rainfall conditions
- Eliminate place where can shelter during day time
- Regular practice of trapping and removing snails
- Removing debris and manage field sanitations
- Proper weed management
- Regular field infection and hand collection
