Summary

Cultivated sorghum, Sorghum bicolor (L.) Moench, is the fifth most important cereal in the world after rice, wheat, maize and barley. The countries with the greatest areas of sorghum production are India (12.9 million ha), Sudan (5.7 million ha), Nigeria and the USA (4.0 million ha each) and Niger (2.35 million ha). Other major producers include Mexico, Argentina, Colombia and Venezuela in the Americas; Burkina Faso, Ethiopia, Mali, Tanzania, Chad, Cameroon, Somalia and Mozambique in Africa; China, Pakistan and Yemen in Asia. In terms of production, the major sorghum-growing countries of the world are the USA (17.5 million t), India (12.4 million t), China (5.1 million t), Mexico (4.4 million t), Nigeria (4.0 million t) and Sudan (3.3 million t). In many other countries, production is much lower but sorghum is a significant part of the agricultural production and a very important food crop for millions of poor farmers. This is particularly true for rain-fed areas of Asia and Africa. In many areas, the stalks and foliage (used as fodder, fuel, thatching and fencing material) are valued as much as the grain.

BOTANY AND DISTRIBUTION

Sorghum bicolor (L.) Moench (2n=20) is synonomous with Holcus bicolor L., Andropogon sorghum (L.) Brot. and Sorghum vulgare Pers. Sorghum has been called great millet, guinea corn, milo, sorgo (English); sorgho (French); sorgo (Spanish, Portuguese); jowar, cholam, jonna (India); kaoliang (China) and durra (Sudan).

Sorghum bicolor is considered an extremely variable crop-weed complex. It comprises wild, weedy and cultivated annual forms which are fully interfertile.
