چکیده	Productivity growth is a major source of economic growth and welfare improvement and works for obtaining economic goals. On the other hand, because of its basic role in providing strategic products and food security, Iranian Agronomy Sub-Sector has an excessive importance in agriculture sector as a main and important sector in Iranian economy. In this research, technical, allocative and economic efficiency, total factor productivity and optimum values for cost minimizing are calculated for strategic agronomy products including wheat, barley, rice, cotton and sugar beet in 15 years during 1995 to 2009 by Malmquist index and data envelopment analysis (DEA) method. Results show that productivity for these products has generally risen in this period. Technical efficiencies are in high levels but allocative and economic efficiencies are in lower levels. Economic efficiency and consequently farmers’ income can increase by optimizing value of inputs and employing more advanced technology and improving agricultural extension.
