General description
It is a common annual erect but branched
weed (rarely cultivated for its seeds in some pocket areas of Ethiopia),
with red leaves, flowers, stalk (smooth) and tassels. Seeds are black and
tiny like teff (Eragrostis tef) seeds. The leaves are alternate. The plant
grows mostly in cultivated fields including home gardens.
Edible part(s),
preparation methods and palatability
Leaves
and young shoots are edible. They are boiled and consumed as vegetable
and the husk of the seed is also used as food in Konso while the young
branches of the stalk are also eaten in South Omo by the Ari people. The
plant seeds are also used for preparation of local beverage known as ‘Chaqa’
in Konso.
The plant is very common and semi-domesticated on farm fields in Konso
and South Omo. Some farmers have started to cultivate and intercrop the
species on their farm fields near their homestead. In Konso the species
is found intercropped with cotton, maize, sorghum and beans.
Nutritional value
The
leaves of Amaranthus spp. are high in vitamin A content and furthermore,
have a high protein content of 27.8%. Fresh leaves contain higher quantities of
both calcium and phos-
phorus than cabbage.Compared
to spinach Amaranthus spp. have greater protein, calcium, phosphorus,
and iron content. The protein of these vegetables contains approximately 25%
lysine, which is absent in some cereals such as maize. The consumption of
these plants together with maize should balance the deficient nutrient.
Agroecology
Most
Amaranthus
species are widespread in tropical and subtropical regions of the world.
They mostly grow as a weed of cultivation in degraded land and built-up
areas, along rivers, roadsides and forest edges. The species grow in the
low- and midlands as well as on higher altitudes (900 – 2,600m) on a wide
range of soils, but they are most common in middle and high altitudes (1,400
- 2,400m).
Propagation
method(s)
Propagates by seeds.
Sample location(s)
Jarso Kebele, Konso
Remarks
There are two species of the weed
that are edible. Their main difference is in seed, leaf and stalk color.
The first one has white seeds and green leaves and stalk while the other
one is with black seeds and reddish leaves and stalk.
