In 1987 wheat was Chad's least important cereal grain. Farmers planted the crop in polders around the shores of Lake Chad, and some small planting also was done in the oases and wadis of northern Chad. Replacing an earlier state operation, the Organization for the Development of the Lake (Société pour le Développement du Lac--SODELAC) was founded in 1967 to organize cultivation and provide wheat for the state-owned flour mill at N'Djamena, the Grands Moulins du Tchad. The flour mill began operations in 1964 but closed in 1980; as of 1987, operations had not resumed. In the late 1970s, plans to plant some 20,000 hectares of wheat in polders failed because warfare around Lake Chad affected the infrastructure of SODELAC and the construction of new polders and because farmers resisted SODELAC-controlled production.
Wheat production generally followed trends similar to the production of other cereals, remaining low in the 1960s and 1970s but reaching a high in 1983. In 1984, however, production fell sharply. The bulk of wheat was traded through traditional channels to those herders in the northern regions of Chad who preferred wheat to millet or sorghum.
