This work examined the production efficiency of cassava farms in Taraba State. A purposive sampling method was used to select 300 cassava farmers in the study area. Important information on inputs used and outputs realized in cassava production were collected from cassava farmers using structured questionnaire. The datacollectedwere analyzed using descriptive statistics, stochastic frontier production function and cost function. The estimated gamma parameter of stochastic frontier production

... ction showed that about 92% variation in output among cassava farmers in the study area was due to differences in technical efficiency. The estimated elasticities of production with respect to farm size, family labour, hired labour and fertilizer were statistically significant at 1% and 5% level of significance respectively. The mean technical, allocative and economic efficiency were 0.887, 0.856 and 0.825 respectively, meaning that the sample farmers were relatively very efficient in allocating their limited resources with technical efficiency appears to be more significant than allocative and economic efficiency. The result of the study showed that the major factor affecting cassava productions in the study area were farm size, family labour, hired labour, fertilizer, house hold size, years of schooling and source of funds. These factors were significant and have positive influence on cassava output. It is thus recommended that farmers should be encouraged to adopt more intensive cultural practices instead of continued expansion in land put to cassava production.
