cowpeas, forage crop, south dakota, summer forage
In the northern Great Plains, cool-season pastures decline in productivity during summer. This reduces available forage supplies. Solutions to forage shortages during the summer traditionally have included the use of perennial and annual warm-season species for pastures, hay, or silage. Cowpeas, a non-traditional crop suitable for summer forage, have been investigated recently at SDSU. Cowpeas (Vigna unguiculata [L.] Walp.) are an important legume in the southeastern United States, but since 1940 they have been replaced gradually by soybeans, clovers, and other legumes. Referred to as “black-eyed peas,” cowpeas are grown primarily for human consumption but also are suitable for hay, silage, and pasture.
