However, with the introduction of upland arrowroot technology, the crop is now grown in many parts of the country.

Arrowroot is a high-value crop that fetches good money for farmers. It is a perennial crop that can be harvested every six months, and one can get mature arrowroot within that time frame. The crop is also highly nutritious and has a high monetary value. As a result, it has become a viable enterprise for many farmers in Kenya.

Many farmers in Kenya are now venturing into arrowroot farming due to its high profitability. With proper tending of the crop, farmers can earn a tidy sum from the sale of arrowroots. In this article, we will explore the various aspects of arrowroot farming in Kenya, including the best practices for cultivation, the potential profits, and the challenges faced by farmers in the industry.

Overview of Arrowroot Farming in Kenya

Arrowroot is an important crop in Kenya, grown mainly for its edible corms. The crop is highly nutritious and is a good source of carbohydrates, dietary fiber, and minerals such as potassium, magnesium, and iron. Arrowroot is also rich in vitamins such as vitamin B6 and vitamin C. In Kenya, arrowroot farming is becoming increasingly popular due to its high demand both locally and internationally.

Arrowroot farming in Kenya is mainly done in highland areas where the climate is cool and moist. The crop grows well in well-drained soils that are rich in organic matter. Arrowroots can be propagated through suckers or by planting the corms. The crop matures within 8-10 months after planting and can be harvested for up to 3 years.

Arrowroot farming in Kenya is mostly done by small-scale farmers who use traditional methods of cultivation. However, with the adoption of modern farming practices, arrowroot farming has become more efficient and profitable. Farmers are now using highland arrowroot technology, which involves planting the crop in trenches 60cm deep and 1 meter wide. This method creates the same conditions as in the river valleys, where arrowroots are traditionally grown.

Arrowroot farming in Kenya has numerous benefits, including providing food security, generating income, and improving soil fertility. The crop is also easy to maintain and requires minimal inputs. Additionally, arrowroot farming has a low environmental impact as it does not require the use of harmful chemicals.

Climatic and Soil Requirements for Arrowroot Farming

Arrowroot is a tropical plant that thrives in warm and humid climates. It requires a temperature range of 21 to 30 degrees Celsius and a rainfall of 1,500 to 2,500 mm per year. The plant prefers a well-distributed rainfall pattern throughout the year, with no prolonged dry spells or waterlogging.

Arrowroot requires a friable, well-drained loamy soil. However, soil at the foot of the hills, in valleys, and newly opened areas are preferable. Clayey soil must be avoided since it induces poor rhizome development and usually causes the deformation of the rhizome, which tends to break during harvesting.

Before planting, it is important to prepare the soil by deep plowing and harrowing to loosen it and remove any weeds or debris. The soil should be enriched with organic matter, such as compost or well-rotted manure, to improve its fertility and water-holding capacity.

It is also recommended to conduct a soil test to determine the soil’s pH level and nutrient content. Arrowroot thrives in a pH range of 5.5 to 7.5, and any deficiencies or imbalances can be corrected with the appropriate fertilizers or soil amendments.

Preparation and Planting of Arrowroot

Land preparation is an essential step in arrowroot farming. The land should be plowed and harrowed two or three times, depending on the soil. Plow deep enough to provide favorable conditions for better root development. It is also essential to remove all weeds, rocks, and debris from the land to avoid competition for nutrients and water.

Arrowroot can be propagated by suckers and rootstock or rhizomes with two or more nodes each. The suckers should be obtained from healthy and mature plants. The planting holes should be 60 cm deep, 1 meter wide, and any desired planting length.

After digging the holes, add a layer of manure mixed with soil at the bottom of each hole. Place the suckers at an angle of 45 degrees with the top node facing up. Cover the suckers with soil and press it firmly to remove any air pockets. Water the newly planted suckers to help them establish quickly.

The spacing of the suckers depends on the desired yield and the available land. A spacing of 30cmx30cm is recommended for big-sized arrowroots. With four suckers in every hole, the farmer covers them with a little layer of soil. After about two weeks, add manure mixed with soil around the plants to provide the necessary nutrients.

It is also important to ensure that the arrowroots are well watered. The plants should be watered regularly, especially during the dry season. The amount of water required depends on the soil type and the stage of growth. Too much water can cause the roots to rot, while too little water can stunt the growth of the plant.

Topdressing should be done between the second and third months after planting. This is done by applying NPK inorganic fertilizer. A 50-kilogram bag adequately caters to one acre. Proper feeding is ultimately what will determine the quality of your arrowroots.

Overall, proper preparation and planting of arrowroot are crucial for a successful harvest. Ensure that you follow the recommended spacing, use quality suckers, and provide the necessary nutrients and water for the plants to thrive.

Arrowroot Farming Practices and Techniques

Arrowroot farming is a profitable venture in Kenya, and it requires proper techniques and practices to ensure maximum yield. Here are some of the best practices and techniques:

  • Soil Preparation: Arrowroots grow well in well-drained and fertile soils. Before planting, the soil should be tilled and mixed with organic matter such as compost or manure to improve soil fertility. The soil should be loosened to a depth of at least 30 cm to allow for proper root development.
  • Planting: Arrowroots are planted by stem cuttings known as suckers. The suckers should be planted in trenches measuring 60 cm deep, 1 metre wide, and 30 cm apart. The planting should be done during the rainy season to ensure proper germination and growth.
  • Irrigation: Arrowroots require a constant supply of moisture to grow well. In areas with low rainfall, irrigation is necessary. Drip irrigation is the most efficient method of irrigation as it conserves water and ensures that the plants receive enough moisture.
  • Fertilization: Arrowroots require adequate nutrients to grow well. Organic fertilizers such as compost or manure can be applied to the soil before planting. During the growing season, nitrogen-rich fertilizers such as urea can be applied to promote growth and yield.
  • Pest and Disease Control: Arrowroots are susceptible to pests and diseases such as nematodes and bacterial wilt. Crop rotation, intercropping, and the use of resistant varieties can help control pests and diseases. In case of an infestation, appropriate pesticides should be used.

By following these practices and techniques, arrowroot farmers in Kenya can achieve high yields and maximize profits.


Pest and Disease Management in Arrowroot Farming

Arrowroot farming in Kenya is a lucrative venture that is gaining popularity due to its high demand and nutritional value.

Harvesting and Post-Harvest Handling of Arrowroot

Arrowroot is usually harvested 8 to 10 months after planting when most of the leaves have turned yellow and shrunk. Harvesting should be done carefully to avoid damage to the rhizomes, which can reduce the quality and yield of the crop. Hand digging and mechanical harvesting are the two main methods of harvesting arrowroot.

If hand digging is used, the soil around the plant should be loosened with a fork or a spade before the rhizomes are gently pulled out of the soil. If mechanical harvesting is used, a harvester or a tractor with a plow attachment can be used to lift the rhizomes out of the soil.

After harvesting, the rhizomes should be washed, peeled, and graded to remove any damaged or diseased rhizomes. The rhizomes can be stored in a cool, dry place for up to two weeks before processing or planting. However, if longer storage is required, the rhizomes should be treated with a fungicide and stored in a cool, humid place to prevent drying out.

Processing of arrowroot involves washing, peeling, grating, squeezing, settling, drying, and grinding into powder form. The starch can then be used for various purposes such as making biscuits, cakes, and puddings, and as a thickener for soups and sauces.

Proper post-harvest handling of arrowroot is important to maintain the quality and yield of the crop. The rhizomes should be handled carefully during harvesting and processing to avoid damage. Storage conditions should be optimized to prevent drying out or rotting of the rhizomes. By following these practices, farmers can ensure a successful and profitable arrowroot farming venture.
