Yellow Beans Farming in Kenya

Yellow beans present a lucrative investment opportunity owing to their high market demand and easy marketability. Additionally, they require minimal inputs and thrive during the short rains. With a short growth period of just two months, they can also serve as an intercropping crop between seasons of your main crop, enhancing overall agricultural productivity.

Ecological requirements

Soil Conditions:

  • Well-drained soil rich in organic matter.
  • pH level of 6.5 to 7.5.
  • Avoid water-logged soils as they result in poor yields.


  • Optimum rainfall between 800 and 2,000mm per year.
  • Well-distributed rainfall throughout the year is preferred.
  • If rainfall is insufficient, irrigation can be employed.
  • Avoid irrigating during the flowering period to prevent flower abortion.

Watering Practices:

  • Avoid overfeeding with water; yellow beans require only a small amount.
  • Irrigate once per week, if necessary.


  • Suitable for diverse altitudes ranging from 1,000 to 2,100 meters above sea level.


  • Tolerates temperatures ranging from 15 to 33°C.
  • Optimum temperature for maximum yields is 20 to 25°C.
  • High temperatures can affect flowering and pod setting.
  • Low temperatures may lead to disease incidences such as blight.

Yellow Beans Farming in Kenya: Planting

Planting and Spacing:

  • Plant beans during the short rains to reduce the impact of heavy rains and waterlogged soils.
  • Avoid planting during cold weather accompanied by short rains to prevent low-quality crops and reduced yields.
  • Alternatively, plant yellow beans during the dry season and water them once per week, avoiding watering during the flowering stage.
  • For pole variety: Optimal spacing is 10×40 cm.
  • For bush variety: Optimal spacing is 20×20 cm.
  • Planting at these spacings allows for approximately 100,000 yellow bean seeds per acre, roughly equivalent to 25 to 30 kgs of seeds.

Nutrient Management:

  • Mix soil with compost organic manure before planting to boost fertility and yields.
  • Two weeks after germination, apply a balanced NPK fertilizer such as 17.17.17 or 23.23.23.
  • Alternatively, apply foliar fertilizer at this time if preferred.

Pest and Disease Management:

  • Be vigilant for pests such as aphids, cutworms, bean fly, caterpillars, whiteflies, and bollworm.
  • Control pest infestations by spraying appropriate chemicals upon early detection.
  • Effective chemicals include Pentagon 50 EC by Greenlife and Umeme by Osho Chemicals.

Pest and Diseases

Disease Management:

  • Bean Rust:
    • Symptoms: Formation of reddish-brown patches on leaves, stems, or pods.
    • Control:
      • Apply a preventive fungicide like Green Copper or Mistress upon early signs.
      • For affected plants, use a curative fungicide such as Trinity Gold or Ridomil.
  • Downy Mildew:
    • Symptoms: Formation of whitish/grey substance on leaves, starting from the underside and progressing to the top.
    • Control: Use a fungicide like Trinity Gold or Milraz.
  • Anthracnose:
    • Symptoms: Brown/black sunken lesions on stems, pods, seeds, or leaves.
    • Control: Spray Absolute 375SC at a rate of 10ml/20l knapsack.
  • Blight:
    • Symptoms: Yellowing and eventual falling off of leaves, discoloration of vascular tissues.
    • Control: Apply a fungicide such as Trinity Gold or Green Copper.

Weeding Practices:

  • Ensure proper and timely weeding to minimize competition for nutrients and resources.
  • Uproot all weeds before planting and remove any weeds growing within the plants by week three.
  • As bean plants spread out, they will naturally suppress further weed growth, reducing the need for additional weeding.
