Amaranthus caudatus
Amaranthaceae


Maelezo

Amaranthus caudatus is a cultivated herbaceous crop originating from South America. Reaching 1.5-2.5 m in height, its simple leaves occur in spiral arrangement along the stem. Inflourescences are large (as long as 1.5 m) and showy, with small, red or green flowers. Small, oval-shaped seeds (1.5-2.5 mm) vary in color from creamy white, reddish, or brown.

matumizi

A pseudocereal, A. caudatus seeds are used similar to grains: roasted, ground into flour, boiled, dried and stored, sprouted, or even fermented for beverages. Leaves are treated as a vegetable and prepared similar to other leafy crops. Plants can also be used for livestock fodder. Because of the showy flowers, A. caudatus is often grown as an ornamental.

kilimo

  • Elevation – up to 3600 m
  • Rainfall – 250-4200 mm
  • Soil Types – 4.3-8.5 pH; well-drained soils
  • Temperature Range – 7-40°C
  • Day Length Sensitivity – none
  • Light – prefers full sun

Scarifiction of A. caudatus seed increases germination rate, but is not required. Seeds can be broadcast or direct seeded in rows. Broadcast rates should be 8-18 kg/ha. When planting in rows, seeds should be 1-1.5 cm deep. Spacing should be 2.5-3.5 cm in-row, and 30-45 cm between-row. A. caudatus can be intercropped with maize.

uvunaji na uzalishaji wa mbegu

A. caudatus exhibits asynchronous ripening—when portions of the seed heads ripen before others—making harvest more intensive. Hand cutting ripe portions as they ripen, and while the plant is still green, will help prevent seed shatter. Leaves may be harvested continuously as needed.

wadudu na magonjwa

Several fungal pathogens affect A. caudatus, as well as caterpillars, stinkbugs, grasshoppers, and aphids.

mapishi na lishe

A. caudatus seeds are high in fatty acids and quality protein, and are gluten-free. They can be roasted, boiled, or dried and stored. Dried seed can be ground for flour, sprouted, or fermented for alcoholic beverages. Leaves can be boiled, stir-fried, or prepared in similar fashion to other leafy crops. A. caudatus is a hyperaccumulator of nitrates from the soil. Depending on fertilizer source, leaves can be high in nitrates, which is an anti-nutritive compound.
