Bambara groundnut has been classified as an underutilized crop and described as a complete food. In this study the dry matter, ash, crude protein, crude fat, neutral detergent fibre (NDF), acid detergent fibre (ADF) and acid detergent lignin (ADL) were determined for nine landraces cultivated in Botswana, Namibia and Swaziland. The Association of Official Analytical Chemists methods were used for the analysis. The results (g/100 g) obtained were as follows: dry matter: 92.17-94.00, ash: 3.57-4.85, crude protein: 17.10-22.94, crude fat: 4.90-7.24, ADF: 6.53-10.65, NDF: 14.10-25.82, and ADL: 0.19-3.44. The landraces grown in Botswana had more protein (20.66-22.94) compared with those grown in Namibia (19.28-20.53) and Swaziland (17.10-19.91). In contrast, the landraces grown in Swaziland had higher values for NDF (16.33-25.82) than those grown in Namibia (15.80-21.19) and Botswana (14.10-21.71). The fat content was overall low which is in line with good nutritional requirements. There were intra and inter country composition similarities and differences among the landraces. The results show that the crop is a good source of protein and fibre.
