Carrot Growing Regions In Kenya

Carrots are cultivated in various regions across Kenya, taking advantage of the country’s diverse agro-ecological zones and favorable climatic conditions. Here are some of the notable carrot-farming regions in Kenya:

  1. Central Kenya: This region includes areas such as Kiambu, Murang’a, Nyeri, and Kirinyaga. The cool temperatures and fertile soils in these highland areas provide suitable conditions for carrot farming. These regions are known for producing quality carrots that are often in demand in local markets.
  2. Rift Valley: Parts of the Rift Valley, including Uasin Gishu, Nakuru, and Bomet counties, have become significant carrot-producing areas. The altitudes and temperate climate in these regions are conducive to carrot growth. Additionally, the availability of irrigation water has contributed to successful carrot farming.
  3. Eastern Kenya: Counties like Meru, Tharaka Nithi, and Embu in Eastern Kenya have also embraced carrot farming. The cooler temperatures in higher altitudes and well-drained soils provide favorable conditions for carrot farming.
  4. Nairobi County: The urban area of Nairobi and its surroundings have seen an increase in urban farming, including carrot farming. Farmers are utilizing small plots and container gardening to grow carrots for local consumption and sale.
  5. Western Kenya: Some parts of Western Kenya, such as Kakamega and Bungoma, have also ventured into carrot farming. The availability of fertile soils and adequate rainfall in these areas supports carrot farming.
  6. Coastal Region: While not as prominent as in other regions, coastal counties like Kilifi and Kwale have experimented with carrot farming. These areas often require careful soil management and irrigation due to their warm and humid climate.

Ecological Requirements On Carrot Farming In Kenya

Climatic requirement on carrot farming in Kenya

Carrots are moderately hardy and also tolerate high temperature but seedlings are more sensitive to both extremes of temperature.

Carrots prefer cool to mild temperatures. The ideal temperature range for carrot growth is 15 to 20 degrees Celsius. Carrots need full sun to grow well. They will not produce good yields if they are shaded.

The best altitude to grow carrots in Kenya is between 700 and 2,000 meters above sea level. Carrots can be grown at higher altitudes, but they may not grow as well. At lower altitudes, the climate may be too hot and humid for carrots to thrive.

Soil Requirement On Carrot Farming In Kenya

Carrot farming in Kenya thrives when rooted in well-prepared soil that meets specific requirements.  The soil serves as the foundation for healthy root development and successful crop yields.

Carrots prefer loose, well-draining soil with a sandy loam or loamy texture. This type of soil structure allows roots to penetrate easily, resulting in straight and uniform carrots. Soil that is too heavy or compacted can hinder root growth, leading to misshapen or stunted carrots.

Additionally, proper soil preparation is essential to remove rocks, stones, and debris that can obstruct root growth. Incorporating organic matter, such as compost or well-rotted manure, enriches the soil with essential nutrients and enhances its ability to retain moisture without becoming waterlogged.

A slightly acidic to neutral soil pH range of 6.0 to 7.0 is ideal for carrot farming, as it promotes nutrient availability and uptake. Ensuring consistent moisture throughout the growing season is crucial; however, excess water can lead to rot. Adequate drainage mechanisms, such as raised beds, can help manage water levels. By adhering to these soil requirements, Kenyan farmers can create an environment that nurtures healthy carrot plants.

Propagation and planting Carrots In Kenya

Seed bed preparation on carrot farming in Kenya

Carrots need finely prepared soil for good seed germination and proper root development. Therefore, fields to be grown with carrots should be ploughed to a depth of 30 cm, finely prepared and levelled. A raised seedbed 1 m wide, 10 m length and 20cm height is prepared especially in areas with poor drainage and during long rainy season. About 40 cm wide furrows are used between the beds for irrigation.

Seed sowing on carrot farming in Kenya

Carrots are established by direct seeding in the seedbed. The seeding rate is about 5 kg per ha. In
rainfed crops, rows 25 cm apart are traced across the width of the seedbed and seeds are drilled 5 cm apart within the row at the depth of 1 cm. In irrigated crops, 4 rows of carrots are sown at the same spacing along the raised seedbed. Seeds are often mixed with sand (2 sand: 1 seed) to ease handling and uniform spacing of seeds.

Carrot seeds are slow to germinate and seedlings are rather weak. Cover the seedbed with grass after sowing and water them adequately. Carefully remove the grass when seeds germinate.

Thinning

Carrots are often densely sown. The plants should be thinned to 5 cm spacing within the row. Thinning results in uniform and good sized roots and avoids lodging of plants. Thinning is done several times beginning from 3rd week after sowing, as plants attain 10-15 cm height or during 1st cultivation. Hand thinning is very expensive thus seed should be sown as thinly and uniformly as possible to reduce the need for thinning.

Intercropping 

Because of their limited space requirements and early growing habits, carrots are ideal for intercropping between other crops such as tomatoes, lettuce or capsicums and because of their  fragrant leaves can help keep pest levels low. Other crops good for intercropping with carrots  include garlic, dwarf bean, onion, parsnip, leek, small peas, pea mange-tout (snow peas), and radish.

The most profitable example of an association is that of carrots and leeks. Carrots have very deep roots that extract nutrients deep in the soil, whereas leeks have extremely superficial roots, which help the crop to extract nutrients near the soil surface. Moreover, carrots can drive away worms from leeks, while leeks can drive away flies from the carrots.

Cultivation of Carrots

Carrots grow very slowly for the first few weeks thus they can’t compete with weeds. Repeated shallow cultivation is necessary to keep down weeds especially in the early stages of growth. Deep cultivation may be injurious to roots as many of them are found within 5 cm of the surface. Keep the top of the roots covered with soil to avoid greening especially with Nantes variety.

Irrigation Requirement On Carrot Farming In Kenya

Carrots grown during dry season, and must be irrigated to accelerate seed germination and root growth. Irrigation has to be supplied every morning and afternoon after sowing seeds using watering can. Furrow irrigation after sowing or at early stage of the crop washes away and displaces seeds and uproots seedlings.

Irrigation can be applied every 5 to 7 days to field capacity depending on soil type and environment. Water-logging should be avoided. Inadequate irrigation increases roughness, decreases root size, and slows growth, and leads to poor color development. Irrigation has to be stopped when the crop matures.

Harvesting Carrots

Carrots are mostly harvested manually by pulling up the roots at the leaves as long as the soil is moist and soft. If the soil has dried, it will be necessary to use either a spade or similar tool to loosen the soil and harvest the roots. Carrots are usually ready for harvesting 60-85 days after sowing. Mature roots should be orange-coloured internally down to the blunt tip.

A good market price can be fetched from young carrots with a fresh top, but leaving the top on dries out the root quickly and reduces the marketing period of the crop. An alternative is to trim the top back to about 2 cm and package attractively.

For mature carrots the tops are trimmed down completely to avoid storage rots before marketing. Carrots can remain in good condition (Shelf life) for 100-150 days when the foliage is removed and they are stored at 1-4° C with 95-100% relative humidity. Carrots should be stored separately from other vegetables to prevent a bitter flavour induced by ethylene (a colourless gas with a sweet odour that is produced by many fruits and vegetables that accelerates the ripening process). Generally carrots store better when they are mature and harvested under moist conditions, and undamaged and free of diseases and pests.

Carrot Seeds In Kenya

An acre piece of land requires at least 2.5 kg of seed. Most carrot seedling sellers in Kenya sell them in packets ranging between 10-500 grams. With an average price of 3,500Kshs per Kg.

The soils must be well prepared and the planting depth should about one centimetre. The spacing is 30cm from row to row by continuous drill at planting time.

Carrot Yield Per Acre In Kenya

Carrot yield per acre in Kenya can vary based on a range of factors, including the carrot variety, soil quality, climate, cultivation practices, and pest management. On average, under optimal conditions and with proper care, carrot yields in Kenya can range from 15 to 25 tons per acre.

It’s important to note that achieving higher yields requires implementing best practices throughout the cultivation process, from selecting suitable varieties to preparing the soil, managing pests and diseases, providing consistent irrigation, and practicing proper spacing and thinning. Additionally, factors such as altitude, temperature, and local weather patterns can influence yields.

To maximize carrot yields, farmers should consider factors such as soil preparation, adequate fertilization, proper spacing, timely irrigation, and effective pest and disease control.

Common Pests and Diseases That Affect Carrot Farming In Kenya

Pests that affect carrot farming in Kenya:

  1. Carrot Fly (Psila rosae): Carrot flies are a major pest that lays eggs near the base of carrot plants. The hatched larvae burrow into the roots, causing tunnels and making the roots unappetizing. Crop rotation, covering crops with fine mesh or using floating row covers, and planting onions or leeks as companion plants can help deter carrot flies.
  2. Aphids: Aphids are small insects that suck sap from carrot leaves and stems. They can transmit plant viruses and weaken the plant. Natural predators like ladybugs and parasitic wasps can help control aphid populations. Insecticidal soap or neem oil can also be used.
  3. Wireworms: These are the larvae of click beetles and can cause damage by tunneling into carrot roots. Proper soil preparation and rotating crops can help reduce wireworm infestations.
  4. Cutworms: Cutworms are caterpillars that cut through plant stems at the soil level, causing young carrot plants to wilt and die. Protective collars around seedlings can prevent cutworm damage.

Diseases that affect carrot farming in Kenya:

  1. Aster Yellows: This disease is caused by a phytoplasma and is transmitted by leafhoppers. It leads to yellowing, stunting, and distorted growth in carrot plants. There’s no cure for infected plants; removal and destruction are the best control measures.
  2. Alternaria Leaf Blight: Alternaria fungi cause brown lesions on carrot leaves, eventually leading to defoliation. Crop rotation and ensuring proper spacing between plants for good air circulation can help prevent this disease.
  3. Cavity Spot (Pythium spp.): Cavity spot is a soil-borne disease that causes brown, sunken lesions on carrot roots. Proper soil drainage, avoiding over-irrigation, and improving soil structure can help reduce its occurrence.
  4. Powdery Mildew: Powdery mildew is a fungal disease that appears as a white, powdery coating on leaves. It can reduce plant vigor and yield. Regular inspection, proper spacing, and fungicide application can help control powdery mildew.
  5. Leaf Blight (Cercospora carotae): This disease causes circular, brown lesions with yellow margins on carrot leaves. Crop rotation, practicing good sanitation, and removing infected plant debris can help manage leaf blight.
  6. Root Knot Nematodes: These microscopic roundworms can cause galls or knots on carrot roots, affecting root development. Rotating crops, using nematode-resistant varieties, and improving soil health can help manage nematode infestations.
