- Intervention effect Cowpea yields in intercropping with sorghum were low compared with sole cropping.
- Intervention effect Intercropping out-performed monocropping in cowpea yield.
- Observation Land equivalent ratios of sorghum intercropped with cowpea were greater than one.
- Intervention effect Intercropping gave higher gross income and cash returns to draught-power than monocropping.
- Intervention effect Intercropping did not increase returns to labour compared with monocropping.
- Intervention effect Differences between intercropping and monocropping were never large and seldom statistically significant.
