Pearl millet (Pennisetum glaucum) is the most widely grown type of millet. Grown in Africa and the Indian subcontinent since prehistoric times, it is generally accepted that pearl millet originated in Africa and was subsequently introduced into India. The earliest archaeological records in India date to 2000 BC, so domestication in Africa must have taken place earlier. Its origin has been traced to tropical Africa. The center of diversity for the crop is in the Sahel zone of West Africa. Cultivation subsequently spread to east and southern Africa, and southern Asia. Records exist for cultivation of pearl millet in the United States in the 1850s, and the crop was introduced into Brazil in the 1960s.
Pearl millet is well adapted to growing areas characterized by drought, low soil fertility, 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.
Today pearl millet is grown on over 260,000 km² worldwide. It accounts for approximately 50% of the total world production of millets.
India is the largest producer of pearl millet. It is locally known as bajra, and is primarily consumed in the states of Haryana, Rajasthan, Gujarat and Madhya Pradesh. Roti (made from pearl millet) has been the primary food of farmers in Gujarat. It is also used to make other Gujarati Dishes like Dhebra or Thepla, Vada etc....
