Malmquist index computed by data envelopment analysis approach was used to estimate the total factor productivity (TFP) growth in cotton production in Iran during 1983-2001. By dividing this index in the two components, technological change and technical efficiency change, two major factors of productivity growth in cotton production were analyzed. Data was obtained from production cost system and other statistical sources provided by ministry of Jahad-e-Agriculture. Results indicated that TFP growth in cotton crop was positive (0.8% per annum) for the period of this study .This figure was different in different provinces of Iran. Maximum growth rate was 6.2% in Fars province and was negative in Kerman, Mazanderan and Golestan provinces. In comparison, technical efficiency growth was more than technological change during 1983-2001.
