Sorghum grain is a genus of flowering plants in the grass family Poaceae. Seventeen of the twenty-five species are native to Australia with the range of some extending to Africa, Asia, and certain islands in the Indian oceans.
One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized, in pasture lands. Sorghum is in the subfamily Panicoideae and the tribe Andropogoneae.
Pearl Millet (BAJRA) (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.
