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 1.5 million hectares to around 1 million hectares in the 1960s and 1970s and falling to levels averaging 750,000 hectares 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 percent of the total area. Between 1980 and 1985, these coarse grains accounted for 80 to 95 percent of all grain production.
