For yam production, result shows that there was a reduction in output among the control group whilst there was a palpable increase in output levels among the microcredit beneficiaries. This is evident in the reduction of average output per farmer from 1650.4 to 1333.4 tubers for the control group and the mammoth increase from 2555.6 to 7483.3 tubers among the treatment group. Table 8 also shows that for the control group, 11.1 percent of farmers produced above 5000 tubers 5 years ago however, none of the farmers produced up to 5000 tubers after 5 years with the majority (66.7 percent) producing between 1000-4999 tubers and some 22.2 and 11.1 percent producing between 500-999 and less than 500 tubers respectively.
