The objective of this study was to estimate the efficiency of arable crop farming in Ijebu Division of Ogun State with Ijebu North East and Odogbolu Local Governments selected as the study area. To achieve this objective, primary data were collected with the use of well structured questionnaires from 120 respondents. Of these, 90 were usable for the analyses. Frontier production function was used in analysing the data. The results show that 56 male and 34 female respondents were interviewed, out of which 73 per cent had formal education and 53 per cent had less than 10 years of farming experience. The computed technical efficiency index shows that maize had the highest number of variables with high technical efficiency index. Based on the fact that the seed input was positively significant for all three crops, a policy implication stemming from this is that government should improve on the availability of these inputs in order to increase the production level of arable crop farmers in the study area.
