A field experiment was carried out to investigate growth, yield and yield components of cassava and mungbean and land use efficiency, economic returns, and the uptake of soil nutrients (NPK). The results showed that total top dry weights, leaf area indices (LAI), yield and yield components of cassava were not affected by intercropping patterns and did on total top dry weights and leaf area of mungbean. Whilst grain dry weights, and pods per plant of mungbean were affected by cropping patterns but not with grains per pod and 1000-grain weights. Land equivalent ratio and combined economic value were mush greater for intercropping patterns than that of the sole crop both cassava and mungbean. Nutrient uptake per hectare of roots, stems, leaves of cassava were unaffected by intercropping patterns but did with that of mungbean due to the differences in plant populations. Total NPK uptake of cassava and mungbean grown together under intercropping patterns was similar to that of sole crop of cassava. However, the margin profit was much greater for intercropping plants than that of the sole crop since market prices were higher and the residues of plant materials of mungbean could be used to improve soil fertility apart from nodules of this legume crop being produced.
