(Vigna sinensis), an annual plant of the family Leguminosae. It resembles the kidney bean and the hyacinth bean. The stems, which are straight or prostrate, measure 20–200 cm long. The leaves are large, ternate, and long-petiolate. The inflorescences contain from two to eight yellowish green flowers. The pods, which measure 8–10 cm long, are cylindrical and linear; they contain four to ten seeds. Cowpea requires heat and moisture. The seeds sprout at a temperature of 12°-14°C; the sprouts are sensitive to spring frosts. The plant is cultivated in many countries, including Denmark, the Netherlands, France, the Federal Republic of Germany, the United States, and China. In the USSR it is grown in Transcaucasia, Middle Asia, the Northern Caucasus, and the southern Ukraine. Cowpea does not grow wild. There are many varieties under cultivation, predominantly on chernozem and clay soils—the soils on which they grow best.

Cowpea seeds are extremely tasty and have great nutritional value (containing 24–28 percent protein and 1.5–2 percent fat). They are used for food and forage. The unripened beans of varieties of the asparagus bean ( Vigna sesquipedalis) are eaten as a vegetable in fresh and canned forms. The foliage is used as pasture feed, hay, silage, and green manure; it is very nourishing and easily digestible and can be eaten by all types of livestock except horses. The yield per hectare (ha) is 126–300 centners of foliage, 45–60 centners of hay, and up to 14 centners of seeds (reaching 30 centners in moist subtropical areas). Cowpea that is grown for seeds is planted in wide rows spaced 50–70 cm apart. Plants that are cultivated for fodder and green manure are sown in rows spaced 30–35 cm apart or are planted broadcast. Cowpea is also planted in mixtures with corn, sorghum, sudan grass, and other crops. The rate of sowing for seeds is 35–40 kg/ha; for green fodder, 50 kg/ha; and for silage in mixtures with other crops, 25–30 kg/ha. The seeds are planted at a depth of 4–9 cm. Plantings of cowpea are damaged by pea and bean weevils, beetles, and pea moths. Countermeasures include chemical and agricultural-engineering methods.

According to her 'the Cowpea is almost set to be commercialized, but you know there are procedures before you make it available to farmers, it has to pass through Varietal Release Committee, you have to do Foundation Seed Multiplication, that takes sometimes, but it's a process towards commercialization, so everything is going to kickstart this year, both the Cowpea and Cotton, but Cowpea will be the first to come out, if it doesn't get to the farmers this year, early next year it will get to them because of their procedures it's going to follow before it gets to the farmers.
