Typical farm from the 1980s, showing intercropping of yams (finyjie in Nafaanra), cassava (dwa), calabash (chrԑ) or gourd and other crops. Banda, 1982.
A young cassava plant (dwa in Nafaanra) growing in an intercropped field. Manihot esculenta was introduced to Africa from the western hemipshere. It can be grown on soils that have been depleted of nutrients by other crops. Its cultivation requires little labor and its tubers, which provide a starchy staple, can be left in the ground for long periods. Other than as a source of calories, the tubers have little nutritional value. Cassava leaves, however, are used as vitamin- and nutrient-rich additions to soups. Lying on the ground around the cassava plant are dried maize stalks (bleju in Nafaanra) left behind from a previous planting cycle. Sabiye, 15 July, 2022.

A roadside agricultural field is planted with cassava (Manihot esculenta). The palmate leaves of the mature plants are visible growing among trees that were left standing when the intercropped field was first prepared. Regular weeding is needed to control spear grass, which can be seen growing at the edge of the field. Cassava is grown for its tubers, which can be harvested over a long period and store well when processed and dried. Its leaves are valued as an ingredient in soups. Planted early in the rainy season (April-May) the tubers mature in 6-18 months, depending on variety. Cassava tolerates poorer soils than yams (Dioscorea sp.), which are a preferred food in the area. Therefore, cassava it is grown in intercropped fields after yams are grown in the first year or two and before fields are left to fallow. Roadside near Nyire, August, 1994.
