Cowpeas (Vigna unguiculata)

  • Description :
    • Indigenous to Africa and well adapted to South African conditions.
    • A drought tolerant summer legume used for pasture, hay or seed production.
  • Climate :
    • Subtropical/ Tropical
  • Moisture Requirements :
    • 350 mm + per annum
  • Soil Preference :
    • Widely adapted to most soil types but does not perform well on wet soils.
  • Sowing Rate :
    • Runner types :
      • 9 – 16 kg / ha :
        • 0.9 m rows – 111 000 plants / ha
        • 0.45m rows – 222 000 plants / ha
    • Upright types :
      • 12 – 20 kg / ha :
        • 12 – 20 kg / ha
        • 1.5m rows – 66 000 plants / ha, A spacing of 10cm between plants in the row is ideal
  • Planting Time :
    • The optimal planting times vary according to cultivar.
    • Cooler areas – mid November
    • Warm to hot areas – mid December
  • Planting Method :
    • Plant on a weed free seed bed as this will limit inputs during the growing season.
    • If the between-row spacing is adapted to the growth habit of the cultivar, the plants will smother weed seedlings after 7 – 8 weeks.
  • Management :
    • For successful establishment, plant only when night temperatures remain above 10 deg C.
    • Choice of cultivar is important as this will affect whether the crop is used as grain, fodder or green manuring.
    • Inoculation of seed is not necessary as the Bradyrhizobium bacteria for nitrogen fixation occur naturally in South African soils. For this reason, N application levels are low.
    • For sandy soils, 0 – 15 kgN/ha is recommended
    • For clay soils, 0 – 5 kgN/ha is recommended
    • High levels of P can promote flower abscission during stress period which will impede seed set.
    • 5 – 10 kgP/ha is normally recommended.
    • K applications are not required where soil K levels are approx. 80 ppm
  • Advantages :
    • Drought tolerant crop
    • Excellent for rotational purposes
    • The quantity of residual N left in the soil to the benefit of the next crop can vary between 20 – 100 kgN/ha
    • Produce reasonably well on acid soils including AR affected soils.
    • Can be used for silage
    • Have a high protein content : 22 – 24 %
    • Cowpea hay compares well to Lucerne hay
  • Limitations :
    • Susceptible to root-knot nematode
    • Very susceptible to weevil infection
    • Seeds can transfer various viral and bacterial diseases
