The purpose of this study is that, whether inputs and insurance protection policy can effect on income inequality or not? The data which was needed for this study was gained by stratified simple random sampling from 573 wheat insured and uninsured farmers in North, Razavi and South Khorasan provinces in 1383. Result of this study showed that wheat farmer’s income tends to inequality as among the effective factors in production, land cultivated has the most shares and insurance has the lowest share in inequality. In other words insurance can lead to improve the income distribution. Climate share in income inequality is more than insurance share and climate share in income inequality of uninsured farmers is more than insured farmers. Also income inequality in North Khorasan with cold climate is more than other two provinces and insurance share in income inequality in Razavi with moderate climate is more than other two Provinces. At end of this study with respect to results, some suggestions are offered.
