Sorghum and Millet
Chad's most important subsistence crops were sorghum, millet, and berebere. Areas under production for these grains showed a downward trend after the mid-1950s, dropping from an average of 15,000 square kilometres to around 10,000 square kilometres in the 1960s and 1970s and falling to levels averaging 7,500 square kilometres between 1981 and 1986. Taking an average for all lands devoted to grain production during the years from 1981 to 1985, according to the Food and Agriculture Organization (FAO), sorghum and millet cultivation accounted for 85% of the total area. Between 1980 and 1985, these coarse grains accounted for 80 to 95% of all grain production.
