In order to investigate the impact of government policies on supply, cropping area and yield of sugar beet during 1981-2003, nominal rate of protection (NRP) was applied as a variable to persuade government’s policies in this study. Results showed that despite of its negative impacts on cropping area, the NRP has positive effects on supply and yield of sugar beet inIran. Moreover, real price of sugar beet has no significant effect on supply, cropping area and yield of sugar beet. The elasticity of supply, cropping area and yield functions with respect to the NRP was found to be 0.2, -0.029 and 0.25, respectively, indicating that the government supports can lead to yield and supply improvement.
