Technical efficiency of small holder cassava production in Anambra state, Nigeria: A Cobb-Douglas stochastic frontier production approach
This study was carried out to analyse the level of input utilization efficiency of cassava farmers in Anambra State. A multistage sampling technique was employed to select a total of 150 respondents for the study. Data collected were analysed using frequency distribution, means and percentages. A Stochastic Frontier Production Function (SFPF) which incorporated inefficiency causes were estimated using Maximum Likelihood Estimation (MLE) technique. The result obtained indicated that the farmers were operating below the production frontier with a mean technical efficiency of 73%. This shows that they are operating below the frontier. With appropriate technology using hybrid planting materials and credit, production can still be increased by 27%. It is recommended among others that credit and hybrid planting materials should be made readily available to the farmers to enhance resource use efficiency.
