Simple notes for farmers
About the crop: This crop is annual. You plant, grow and harvest it in one main season, then plant again. You can normally start harvesting about 75 days after planting, depending on care and variety.
Main use: Farmers mostly grow this crop for green leaves, fresh pods, dry grain for food, and haulms for animal feed..
Pollination: This crop is mainly pollinated by self. Keeping flowers healthy and having insects like bees in the field helps improve fruit set and yields.
Where it grows: Cowpea (kunde) is grown in many warm and dry parts of East Africa, often together with maize or sorghum. It is grouped under: Legumes & Pulses.
Best climate: This crop does well in warm areas where the temperature is usually between 22 and 32 degrees Celsius. It prefers places that receive around 400 to 700 millimetres of rain in a year. It can grow from near sea level up to about 1800 metres above sea level.
Soil: The crop grows best in slightly acidic to near neutral soils, with a pH of about 5.5 to 7. It does well in light to medium textured, well-drained soils. cowpea (kunde) tolerates poorer soils better than many other crops.. Good drainage is important, so avoid waterlogged spots.
Plant spacing: Plant in rows about 45 centimetres apart, and leave about 20 centimetres between plants in the row. This gives each plant enough space for roots and canopy to spread.
Planting depth: Dig planting holes or furrows about 3 centimetres deep so the roots sit firmly in the soil but are not buried too deep.
Seed or planting material: Use around 20 kilograms of seed or planting material per hectare. Spread or plant evenly so the field has a good stand without being overcrowded.

| Name | Country | Maturity | Traits |
|---|---|---|---|
| Improved kunde – early maturing | KE | 70 | Early Cowpea (kunde) for short rains; good grain and leaf yield. |
| Dual-purpose Cowpea (kunde) | TZ | 80 | Grown for both grain and fodder; good drought tolerance. |
| Local kunde landrace | KE | 75 | Preferred taste and leaf quality; moderate yield. |
| Stage | Product | Rate (kg/ha) | Notes |
|---|---|---|---|
| Basal | NPK 10-26-10 or DAP (small dose) | 40 | Provides starter phosphorus for Cowpea (kunde) root growth and nodulation. |
| Topdress (optional) | Muriate of potash (MOP) or NPK with K | 20 | Target fields with potassium deficiency; helps grain filling and plant strength. |
| Name | Type | Symptoms | Management |
|---|---|---|---|
| Aphids | pest | Clusters of small green/black insects on young shoots and undersides of leaves; leaves curl and plants look sticky. | Encourage natural enemies (ladybirds, lacewings), avoid overuse of chemicals and use selective sprays only when heavy in... |
| Flower thrips | pest | Silvering and browning of flowers, poor pod set, deformed pods in Cowpea (kunde). | Plant early, avoid very late sowing and use recommended insecticides only when damage is severe. |
| Pod borers (Maruca and others) | pest | Holes in pods, webbing and damaged seeds inside pods. | Scout during flowering and early podding, and use recommended biopesticides or insecticides early when damage starts. |
| Cowpea weevil (in storage) | pest | Small holes in stored Cowpea (kunde) grain and powdery dust in bags. | Dry grain well, use airtight storage or treated storage technologies and clean stores between seasons. |
| Leaf spots and blights | disease | Brown or black spots on leaves; severe cases cause early leaf drop. | Use clean seed, rotate with non-legume crops and avoid overcrowding. |
| Root rots | disease | Plants of Cowpea (kunde) wilt and die, roots are dark and rotten in wet spots. | Improve drainage, avoid planting kunde in low, waterlogged areas and rotate fields. |
