3.6. Relative profitability of the various crop rotations
Results of the economic analysis indicated that all crop sequences except the speargrass fallow resulted in a net positive revenue between US$34 and US$1827 corresponding to return on investment ranging from 10 to 254% during the first three cropping seasons (Table 5). The cassava cropping resulted in the highest return on investment whereas mucuna–maize–mucuna recorded the lowest return on investment.
