It is closely related to the cowpea and the savings yellow Without. Taxonomically it is passed either as a subspecies cylindrica or catjang or variety group ' biflora ' Vigna unguiculata by.

Features

It is very similar to the nominate the type of cowpea. It grows to 80 cm tall shrubby or creeping - twining 30 cm high. The trifoliate leaves are on long stalks. The terminal leaflets is 6 to 16 cm long. The flower clusters stand upright and wear pairs 4 to 12 flowers. The flower color is variable, ranging from white to purple and blue.

Cultivation

The Catjangbohne is originally from Africa, but came very early to Asia. Here is today their growing focus where it is used as a dry bean and vegetable. Statistics are lacking.

It is mainly grown in the lowlands of the tropics and subtropics, in the tropics it grows at altitudes of 2000 meters. The precipitate should be 700-1700 mm, the encoder is mounted so that the harvest after the rainy season takes place. Excessive rainfall lead to high leaf mass and low semen volume. The temperature should be between 12 and 28 ° C, the soil pH between 5 and 7.5. The plants also thrive on light soils, medium and heavy soils lead to higher yields. The yields are usually less than one ton of seed per hectare.

Use

Dark seeds are often used as animal feed, the bright tend to be eaten by humans. You will be awarded a better digestibility. Leaves and young pods are eaten as a vegetable or salad. The whole plants are recovered as green fodder and then supply 20-40 tonnes of green matter per hectare.
