Sorghum farming guide — Kenya

Soil requirements, top counties, seed varieties, fertilizer plan & economics

Quick answer

To grow sorghum in Kenya, aim for soil pH 58 (clay soils); the best-suited counties are Kajiado, Baringo, Lamu, Taita Taveta, Tana River. Apply DAP or NPK at planting and top-dress with CAN at Week 4 and at flowering. A well-managed crop yields about 1,200 kg/acre (~KES 81,600 gross per acre).

Growing conditions for Sorghum

Annual rainfall

Altitude

Sorghum does best with 250700 mm of rainfall a year at 01,800 m above sea level. In drier areas, irrigation or water harvesting closes the gap; outside the altitude band, growth and yields drop.

Optimizing soil and fertilizers for Sorghum in Kenya

To achieve maximum yields when farming sorghum in Kenya, managing soil suitability is crucial. This crop performs best within a soil pH range of 5 to 8. Soils that fall outside this range can lock out essential macro and micro-nutrients, leading to stunted growth or crop failure. For acidic soils, applying dolomitic or calcitic agricultural lime is recommended at least 30 days before planting to normalize acidity.

Fertilizer application should be calibrated based on the crop’s nutrient demands. Sorghum has a low nitrogen requirement, low phosphorus requirement, and low potassium demand. Using certified seed varieties suited for your specific altitude and rainfall pattern, combined with a precise basal and top-dressing program (such as applying CAN at Week 4 and at flowering), ensures high crop quality and protects your overall farm investment.

How to grow sorghum in Kenya

  1. 1
    Prepare the soil
    Ensure soil pH is between 5 and 8. Preferred texture: Clay. Apply agricultural lime if your pH is below 5, ideally 30 days before planting.
  2. 2
    Plant at the right time
    Plant sorghum during Long Rains (Sowing & Basal Fertilizer–Bird Control & Scouting) or Short Rains (Sowing & Basal Fertilizer–Bird Control) or Dry Season (Harvesting & Drying–Seed Selection), timed to the start of the rains.
  3. 3
    Apply basal fertilizer
    Sorghum needs low nitrogen, low phosphorus, and low potassium. Apply a balanced basal fertilizer such as DAP or NPK at planting.
  4. 4
    Top-dress
    At Week 4 and at flowering, apply 0.5 bag(s) per acre of CAN. Apply at vegetative stage then repeat at early flowering for grain development.
  5. 5
    Monitor and harvest
    Scout regularly for pests and disease. Expected yield is about 1,200 kg/acre at roughly KES 68/kg.

Frequently asked questions about sorghum farming in Kenya

What soil pH is best for growing sorghum in Kenya?

Sorghum grows best in soil with a pH of 5 to 8. If your soil is more acidic than pH 5, apply agricultural lime about 30 days before planting to raise the pH and free up nutrients. The preferred soil texture is clay.

Which counties are best for sorghum farming in Kenya?

By soil suitability, the top counties for sorghum are Kajiado, Baringo, Lamu, Taita Taveta, Tana River. A full ranking of all 47 counties, each with a suitability score, is shown above.

What fertilizer does sorghum need?

Sorghum has low nitrogen, low phosphorus, and low potassium requirements. Apply a balanced basal fertilizer such as DAP or NPK at planting, then top-dress with 0.5 bag(s) per acre of CAN at Week 4 and at flowering.

When should I plant sorghum in Kenya?

Plant sorghum during Long Rains (Sowing & Basal Fertilizer to Bird Control & Scouting) or Short Rains (Sowing & Basal Fertilizer to Bird Control) or Dry Season (Harvesting & Drying to Seed Selection), timed to the start of the rains in your area.

How much can I earn from sorghum per acre in Kenya?

Sorghum yields about 1,200 kg per acre. At a market price of roughly KES 68/kg, that is around KES 81,600 per acre in gross revenue, before input and labour costs.
