Pearl millet
Pearl millet (Cenchrus americanus, commonly known as the synonym Pennisetum glaucum) is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The center of diversity and suggested area of domestication for the crop is in the Sahel zone of West Africa.
Pearl millet has ovoid grains of 3–4 millimetres (1⁄8–5⁄32 in) length, the largest kernels of all varieties of millet (not including sorghum). These can be nearly white, pale yellow, brown, grey, slate blue or purple. The 1,000-seed weight can be anything from 2.5 to 14 g with a mean of 8 g.
The height of the plant ranges from 0.5–4 metres (1 ft 8 in – 13 ft 1 in).
Pearl millet varieties from the world collection probably have more variation in physical characteristics than any other millet. Kernel shape has different classifications: obovate, hexagonal, lanceolate, globular and elliptical. In Africa, pearl millet is classified as either globular or lanceolate and hexagonal. Most of the millets are very similar to each other in basic structures, although there are some very specific differences.
Recent archaeobotanical research has confirmed the presence of domesticated pearl millet on the Sahel zone of northern Mali between 2500 and 2000 BCE. The Sahel zone is the species' center of diversity and suggested area of domestication.
Pearl millet is well adapted to growing areas characterized by drought, low soil fertility, low moisture, and high temperature. It performs well in soils with high salinity or low pH. Because of its tolerance to difficult growing conditions, it can be grown in areas where other cereal crops, such as maize or wheat, would not survive. Pearl millet is a summer annual crop well-suited for double cropping and rotations. The grain and forage are valuable as food and feed resources in Africa, Russia, India and China.
Today, pearl millet is grown on over 260,000 square kilometres (100,000 sq mi) of land worldwide. It accounts for about 50% of the total world production of millets.
World production of millets has been stable during the 1980s. According to FAO, 39.4 million hectares (97 million acres) of millet were planted in 1987 with an average production of only 704 kilograms per hectare (628 lb/acre).
