Pearl Millet

Sowing: Being frost-tender, pearl millet is direct-sown outdoors only after the soil has warmed past 70°F, since cool soil or a root-bound start stunts the seedlings; germination follows within a couple of weeks once conditions are warm. Plants are typically spaced about 12 inches apart in full sun, a site they require since they do not tolerate shade.

Siting and water: The crop is adapted to poor, infertile, and drought-stricken ground and tolerates dry soils well, but overly wet or waterlogged conditions cause poor seed set, so clay soils need good drainage. Once established it grows rapidly on a robust root system, reaching several feet tall in a single season, and while it tolerates neglect it grows more vigorously with early fertilizer applications and consistent watering.

Management: Where grown as forage, cutting or grazing it frequently keeps quality at its best; left to grow tall, the crop declines in quality and becomes harder to dry properly.

Rust and leaf spot are potential diseases, and the crop can be damaged by chinch bugs and stink bugs; aphids occasionally infest plants as well.

Grain: Pearl millet is typically ready to harvest around 90 days after planting, once the grains have hardened and the plant has turned golden brown; it is cut by hand with a sickle or mechanically with a combine, then left to dry in the field for several days before threshing separates the grain from the chaff, with careful drying and storage needed afterward to prevent mold and insect damage.

Spikes: For cut-flower or dried use, the bottlebrush-like flower spikes are harvested once fully developed but just before the pollen sheds.

Culinary: The grain is eaten raw or cooked and used like rice in sweet or savory dishes, ground into flour for bread or porridge, or fermented into various foods; the sweet raw grains are also eaten directly by children in the regions where it is grown.

Forage: Pearl millet is widely grown as a summer forage crop and hay for livestock, and in the United States it is a common ingredient in birdseed mixes, with its seed heads also attractive to wild birds.

Ornamental: Its showy, foot-long bottlebrush flower spikes and coarse foliage make it a striking vertical accent in beds, borders, and containers, and the spikes are used as fresh cut flowers or in dried arrangements.

Other traditional uses: The plant has also served as a dye source and has documented traditional medicinal use in the African communities where it has long been cultivated.

Pearl millet originated in Central Africa and is counted among the world's oldest cultivated grains, having been grown as a food and forage crop across Africa and the Indian subcontinent since prehistoric times. It became a vital subsistence crop in the arid lands surrounding the Sahara Desert and in West Africa, where its tolerance of poor soils and low rainfall suited the region's challenging growing conditions, and cultivation has since spread to warm regions worldwide.
