The method of analyses used includes the decomposition of relative prices of estate crop commodities and direct, indirect and total protection rates. The results show that the real prices of main estate crops in the period of 1985 - 1997 experienced, a decrease compared to that 1979 - 1985. However in the period of 1997 - 2005, the real prices of cocoa and rubber, but not for coffee , tea and CPO , showed an increase compared to the preceding periods. The indirect protection , in general indicated an increase, however, the direct protection, showed a decrease. In total , the rate protection of the estate crops resulted in positive value eventhough it seamed to decrease from time to time. Term of trade of estate crops againts the importing sugar, from 1979 to 1997 showed a decrease but they were still in positive values. The decreasing performance o of main estate crops would be more significant with respect to the capacity to import. In the future , it is suggested , it is seggested that the government of Indonesia should adjust its interventions continuosly by taking into account tha international price movements of main estate crops to give incentives t to producers and exporters. in general indicated
