On-farm trials, involving intercropping of banana with cowpeas (Vigna unquiculata), dasheen (Colocasia antiquorum), groundnuts (Arachis hypogaea), maize (Zea mays), eddoe (Colocasia esculenta), tannia (Xanthosoma sagittifolium), snapbeans (Phaseolus vulgaris) and their mixtures, were initiated in four different production environments in the Windward Islands. At each site, the existing farmers' intercropping practice was included as control. The results indicate that the cropping systems did not significantly influence the yield (except in Experiment 2), cropping cycle and nutrient concentrations of banana. The cropping systems, Banana + 2 Tannia + 3 Snapbeans, was economically superior (154%) to the control (B + IT) in Grenada. Inclusion of cowpeas in the mixture reduced the yield of dasheen and eddoe considerably.
