Box, Shambu, Ethiopia Abstract: The aim of the study was to estimate technical efficiency of smallholder farmers in maize production in case of Jardega Jarte districts with specific objectives to estimate the level of technical efficiency and to identify factors affecting technical efficiency in the study area. The study used cross-sectional data and the data were collected from sample representative respondents of 168 randomly selected farm households. Cobb-Douglas production function and the Stochastic Frontier Model were used to identify factors influencing productivity and efficiency. The hypotheses tests confirm that, the adequacy of Cobb-Douglas the appropriateness of using SFA the joint statistical significance of inefficiency effects; the appropriateness of using Half- normal and Exponential distribution for one sided error; and nature of the stochastic production function. The maximum likelihood parameter estimates showed that all input variables have positive and significant effect on production. The estimated Cob Douglas production function revealed that all inputs labor in hour, maize cultivated land, Dap, Urea, Seed, oxen have positive
