A wide diversity of foodcrops is grown in Uganda. In different regions different crops predominate; for instance, bananas form the staple in the high rainfall areas of the south whilst cereals become more important in the north. Some food crops such as bananas, cassava, sweet potato and various lentils are produced primarily for local, i.e. on-farm or rural, consumption, whilst others, such as maize, groundnuts, Irish potatoes and rice, are for export from the area of their production.
