This study determines the technical efficiency level and socioeconomic characteristics that
influence the technical efficiency of yellow pepper farmers. Stochastic Frontier function that
incorporated inefficiency factors was estimated using a Maximum Likelihood technique to
provide estimates of technical efficiency and its determinants using data obtained from 60
Nsukka Yellow pepper farmers in Nsukka, Enugu State, Nigeria. The result shows that the mean
technical efficiency was 70 percent indicating the need for improvement in efficiency level for
additional 30 percent.

 The result also indicates that the respondents are operating in the rational
stage (stage II) of production as indicated by the return to scale of 0.797. The empirical findings
also show that age, number of years spent in formal education, family size and farming
experience are important socio-economic determinants of the respondents’ level of efficiency.
Farming experience had positive influence on the respondents’ level of efficiency. It was
recommended that rural women should be effectively mobilized for full participation in the
production of Nsukka yellow pepper through the use of extension agents and community leaders,
provision of farm inputs through establishment of channels that will enable farmer access credit
facilities and review of land use act to give the rural farmers access to land.
