Kodo millet is native to the tropical and sub-tropical regions of South America and domesticated in India 3,000 years ago. Kodo millet is extensively grown on the poorest of soils throughout India but is probably not cultivated to any extent elsewhere. It is reputed to be extremely hardy, drought resistant and grows on stony or gravelly soils which would not support other crops. It is relatively long in duration requiring four to six months to mature compared with two to four months for the other miIlets. Short duration varieties have now been developed. Kodo is an annual tufted grass that grows up to 90 cm high. The grain is enclosed in hard, corneous, persistent husks that are difficult to remove. The grain may vary in colour from light red to dark grey.
