In this article, measurement and analysis of productivity growth are studied by use of two approaches of "Time Trend" and "General Index" for years 2002-2007. Then, the measured productivity growth by Time Trend and General Index approaches are compared with measured productivity growth through Divisia Index approache for the studied provinces and the years. Results indicate that General Index approach is in less contrast with Index Number in comparison with to Time Trend Approach. So, by use of General Index approach, one could better attain the targeted results in comparison with Divisia Index and it is more applicable in research studies. Also results indicate that technical changes for the studied years have had their growth, resulting in increasing "return to scale" in irrigated wheat production.
