Which bean variety is most profitable in Kenya?

Rosecoco (GLP 2, the speckled 'nyayo' bean) is the market favourite and usually fetches the best price because consumers prefer it. Wairimu (GLP 1004, small red) and Mwitemania (GLP 92, red mottled) are also strong sellers. Yellow beans (Nyota, Faida) and canning types like Mexican 142 (for the export/processing market) have growing niche demand. Choose a certified variety your buyers want and match maturity to your rainfall.

How many bags of beans can you harvest per acre in Kenya?

A well-managed acre of certified bush beans typically yields 5–10 bags of 90kg (about 450–900kg), with top farms reaching the higher end. Yields fall sharply with poor seed, drought or waterlogging at flowering, and uncontrolled diseases like anthracnose and pests such as aphids and bean fly. Good spacing, clean seed and timely pest control are the biggest yield levers.

When should I plant beans in Kenya?

Beans are a short-season crop (about 70–90 days) grown in both the long rains (March–April) and short rains (October–November) across most of the country. Plant with the first reliable rains so flowering and pod-fill do not coincide with a dry spell or heavy waterlogging. Because beans mature fast, they fit well as a sole crop, in rotation with maize, or intercropped with maize.

How do I control pests and diseases in beans?

The main problems are bean fly (stem maggot) early on, aphids, thrips and pod borers at flowering, and diseases like anthracnose, angular leaf spot, rust, halo blight and root rots. Use clean certified seed, treat seed against bean fly where recommended, scout from emergence, spray recommended insecticides and fungicides at flowering and pod-set, rotate with cereals, and avoid waterlogged fields. In storage, dry well and use hermetic bags or a protectant to stop bruchid weevils.

Do beans need fertiliser in Kenya?

Beans are legumes and fix much of their own nitrogen, so they need little N. A modest application of phosphate fertiliser (DAP or a P-rich NPK) at planting boosts root and nodule development and lifts yield, especially on phosphorus-poor or acidic soils. On acidic soils, lime plus phosphate gives a strong response. Avoid heavy nitrogen, which pushes leafy growth at the expense of pods.

Where can I sell dry beans in Kenya for a good price?

Beans have strong, steady demand — they are a staple in every Kenyan home, school and institution. Sell to local traders and millers, wholesale markets (Nairobi's Nyamakima and Wakulima, Nakuru, Eldoret), cooperatives and aggregators, institutional buyers (schools, hospitals, the WFP/relief supply chain), processors and canners, and direct buyers on Agrisoko. Grade for clean, uniform, unbroken seed of a preferred variety to earn the top price.

Dry Beans Farming in Kenya (2026 Guide): Rosecoco, Wairimu, Agronomy & Markets

Dry beans are Kenya's most important pulse and, after maize, the second staple on most family plates. From the speckled Rosecoco in a plate of githeri to red Wairimu and Mwitemania in a pot of stew, beans are eaten in every home, school and institution across the country — which means steady, year-round demand and a dependable market for farmers. Beans are also fast (about 70–90 days), improve the soil as a nitrogen-fixing legume, and fit neatly into rotations and intercrops with maize. This guide covers growing dry beans profitably in Kenya — variety choice, agronomy, pest and disease control, and markets — with realistic 2026 Kenyan numbers.

Where beans grow in Kenya

Beans grow across most of Kenya's medium and high-potential zones, roughly 1,000–2,100m above sea level with 400–1,200mm of rainfall per season. The main producing regions include:

Central and Mount Kenya: Kiambu, Murang'a, Nyeri, Kirinyaga, Embu, Meru — often intercropped with maize.
Rift Valley: Nakuru, Narok, Bomet, Nandi, Uasin Gishu, Baringo.
Western and Nyanza: Bungoma, Kakamega, Trans Nzoia, Kisii, Nyamira.
Eastern: Machakos, Makueni and Kitui (shorter-season, drought-tolerant types).

Beans dislike two extremes: waterlogging (which causes root rot and kills the crop) and drought at flowering (which aborts pods). Well-drained soils, the right planting date and a variety matched to your rainfall are the foundation of a good bean crop.

Choosing the right variety

Variety choice is driven by market preference first, then maturity and disease tolerance.

Variety	Type	Maturity	Market notes
Rosecoco (GLP 2)	Large speckled/red mottled	Medium (~85–90 days)	The market favourite; usually the best price
Wairimu (GLP 1004)	Small red	Medium	Strong, steady demand; good yielder
Mwitemania (GLP 92)	Red mottled	Medium	Popular in stews; good market acceptance
Nyota / Faida	Yellow, biofortified	Medium, fast-cooking	Growing demand; iron/zinc rich, quick to cook
Mexican 142	Small white/navy	Medium	Canning and processing market
KAT B1 / KAT B9	Drought-tolerant	Early	For drier Eastern zones

Rule of thumb: grow what your buyers pay most for — usually Rosecoco — unless you have a specific contract (canning, biofortified, or drought zones). Always plant fresh certified seed; recycled seed carries disease and loses vigour.

Season calendar

Period	Activity
February–March	Land preparation, buy certified seed and phosphate fertiliser
March–April	Plant long-rains crop with first reliable rains
Weeks 1–4	Early weeding, scout for bean fly
Flowering (~35–45 days)	Spray for aphids/thrips/pod borers and anthracnose; ensure moisture
~70–90 days	Pods dry, harvest, dry and thresh
October–November	Plant short-rains crop in bimodal areas
December–January	Short-rains harvest, drying, grading and selling

Land preparation, planting and fertiliser

Prepare a fine, well-drained seedbed. Beans are highly sensitive to waterlogging — make drainage furrows on heavy or flat land.
Spacing: about 45–50cm between rows and 10–15cm within the row for bush beans, one to two seeds per hole, sown 3–5cm deep. This gives a full stand and good air circulation to reduce disease.
Fertiliser: apply a modest phosphate dose at planting (DAP or a P-rich NPK) to build roots and nodules. As legumes, beans fix their own nitrogen — avoid heavy N, which delays podding. On acidic soils, lime plus phosphate gives a strong response.
Rotation and intercrop: rotate beans with maize or cereals to break disease cycles, or intercrop with maize (common in Central and Meru) to earn two crops from one field.

Pests, diseases and weed control

Bean fly (stem maggot): The main early pest; seedlings wilt and die. Use seed dressing where recommended and plant early into a firm seedbed.
Aphids, thrips, pod borers: Attack from flowering; scout and spray recommended insecticides at flowering and pod-set — the stage that decides yield.
Anthracnose, angular leaf spot, rust, halo blight: Fungal and bacterial diseases worse in wet, humid conditions. Use clean certified seed, wider spacing for air flow, rotation, and fungicides where justified.
Root rots: Avoid waterlogged, continuously cropped land; rotate and improve drainage.
Bruchid weevils (storage): Dry grain well and store in hermetic (PICS) bags or with an approved protectant — bruchids can ruin market quality within weeks.
Weeds: Keep clean for the first 3–4 weeks; beans compete poorly early on.

Indicative costs, yields and gross margin (per acre, 2026)

These are indicative ranges and vary with variety, soil, management, input prices and season — a planning guide, not a guarantee.

Item	Indicative KES per acre
Land preparation	4,000–7,000
Certified seed (about 25–30kg)	4,000–7,000
Fertiliser (phosphate at planting)	3,500–6,000
Pesticide + fungicide	3,000–7,000
Planting + weeding labour	5,000–9,000
Harvesting, threshing, drying, bags	4,000–8,000
Total variable cost	~23,500–44,000
Yield (well managed)	5–10 bags (90kg)
Farm-gate price (indicative)	KES 8,000–14,000 / 90kg bag
Gross revenue	~40,000–140,000
Indicative gross margin	~20,000–100,000

Bean prices are typically much higher per kilo than maize, and demand is constant — which is why a well-managed bean crop can out-earn maize on the same land, and why beans are such a valuable rotation and intercrop partner.

Harvesting, drying and storage

Harvest when most pods are dry and rattling — uproot whole plants or pick pods, then dry further on a tarpaulin before threshing (by beating in bags or mechanically). Dry grain to about 12–13% moisture for safe storage. Clean and grade for uniform, unbroken seed of a single variety — mixed or broken beans fetch less. Protect against bruchid weevils with hermetic bags or an approved protectant, and store off the floor in a dry, ventilated place so you can hold for a better price.

Where and how to sell your beans

Beans enjoy some of the steadiest demand in Kenyan agriculture:

Local traders and wholesale markets: Nairobi's Nyamakima and Wakulima, plus Nakuru, Eldoret, Kisumu and county markets.
Institutions: Schools, colleges, hospitals, prisons and relief buyers (WFP supply chains) buy graded beans in volume.
Processors and canners: Contract demand for canning types (e.g. Mexican 142) and biofortified varieties.
Cooperatives and aggregators: Bulking improves bargaining power and access to structured buyers.
Direct buyers on Agrisoko: List your beans with variety, grade and moisture stated clearly to reach buyers beyond the local broker.

Grade well, state your variety, and compare buyers rather than accepting the first offer. Before agreeing any price, check the live bean price and the broader market intelligence dashboard so you negotiate from data.
