Adamawa Plateau
Many of the North's ethnic groups farm on small plots for subsistence. The chief among these are the Mbum and Duru. Sorghum, millet (both fast- and slow-growing), and maize are the staple crop throughout most of the province, though manioc (cassava) is also important on the Adamawa Plateau, and rice is especially popular in cities. Other crops include yams along the Lagdo Reservoir and at Tcholliré and groundnuts in the Mayo-Rey division.
