Productivity of what in Ethiopia is below potential. This could be attributed to a number of factors among
which is lack of knowledge on how to use new wheat crop production technologies. Therefore, this study was conducted to estimate the technical efficiency of smallholder wheat producers and identify its determinants in Soro district of Hadiya zone, southern Ethiopia. Cross sectional data from a random sample of 125 wheat producing farmers were collected during the 2015/16 main production season and analyzed. A Cobb-Douglas Production Function and Stochastic Frontier Analysis were employed to achieve the objectives. The results revealed that the mean technical efficiency of wheat producing farmers was 72%. The discrepancy ratio gamma (γ), which measures the relative deviation of output from the frontier level due to inefficiency, was about 63%. This implies that about 63% of the variation in wheat production among the sample farmers was attributed to technical inefficiency effect. The estimated inefficiency parameters showed that age, education level, land ownership, fertility status of the plots and
extension contact negatively and significantly affected technical inefficiency of wheat production showing that an increase in the value of the variable attached to the coefficient means the variable negatively contributed to inefficiency level or conversely it contributed positively to efficiency levels. However, land fragmentation positively and significantly affected technical inefficiency showing that this variable has a negative influence on technical efficiency.
