A field experiment was conducted in 2010 and 2011 at the Teaching and Research Farm, Federal University of Agriculture, Makurdi, Nigeria. The aim was to determine the suitability of some landraces of bambara groundnut for intercropping at varying planting densities with maize. The experiment was a 2×3×3 split-split plot laid in a randomized complete block design with three replications. Intercropping decreased number of pods and grain yields of bambara groundnut component. Number of pods and grain yields increased with increased planting density. Productivity indices indicated that bambara groundnut/maize intercropping was productive, and maize was the dominant component. The marginal rate of returns for the best combinations was 116.13%, suggesting profitability of the intercropping systems.
Key words: Bambara groundnuts, maize, intercropping, planting density.
