gross margin (Tk. 9,875/ha or US$169/ha). Therefore, considerable scope exists to improve
the productivity performance of the average farmers. One way to assess the extent of such
scope is to empirically estimate technical efficiency in wheat production and identify its
determinants, which forms the main objective of this research.
The paper proceeds as follows. The next section briefly describes the history of Research
and Development of wheat crop in Bangladesh. Section 3 describes the analytical framework,
study areas and the data. Section 4 presents the results. The final section concludes and draws
policy implications.
