Pearl millet (Pennisetum glaucum) is a drought-tolerant, annual grass crop primarily grown in arid and semi-arid regions of Africa and Asia, known for its small, round grains and ability to thrive in hot, dry conditions with low soil fertility; it is a staple food in many areas, often used to make flatbreads and porridge, and is also used as animal fodder due to its high nutritional value.
