Cowpea (Black-eyed Pea)
Cowpea is a warm-adapted, variable legume grown for dry seed, green peas, pods, leaves, forage and cover-crop uses. Black-eyed pea is one familiar seed market class within this species.
Profile
- Common names
- Cowpea is also called black-eyed pea, southern pea and crowder pea.
- Growth
- Cultivars range from vining forms to more upright bush types.
- Adaptation
- Cowpea is described as more drought tolerant than soybean and adapted to sandy soils.
- Uses
- The crop can be harvested for dry seed, fresh peas, green pods, greens or forage.
Water & soil context
- Moisture (VWC)
- Maintain adequate root-zone moisture for establishment and reproductive growth, while avoiding waterlogging; the cited publications do not provide a numeric target.
- Salinity tolerance
- Salt sensitivity is not documented in the cited pages.
- Drought tolerance
- The Iowa State-hosted crop guide describes cowpea as more drought tolerant than soybean; a formal drought class is not specified.
Illustrative monitoring-depth band
3–8 in
Editorial placement example, not a validated optimum or total rooting depth. Confirm the site's root distribution and soil horizons; multiple depths may be needed.
Practical irrigation timing should follow local soils, rainfall and growth stage; no universal sensor threshold is documented in these publications.
Problems to watch
- Inspect for insect pests and diseases described in regional cowpea production guidance.
Stress signs
- Wilting and reduced growth can signal water stress; check soil and root-zone conditions before concluding the cause.
Where you'll find it
- Dry seed
- Fresh shelled peas and green pods
- Leafy greens, forage and cover crop
