- Abstract Agro-chemical inputs (fertilizer and pesticides), have contributed in growing economics of Indonesia, which in 1970-1989 demonstrated a spectacular increase in rice production. Since the agro-chemical inputs possess two contradictive characteristics of enhancing yield and preventing yield loss on one hand, and threatening human health and environment on the other hand, a study that reviews the real contribution of agro-chemical inputs on rice production is needed. The objective of the study is to determine whether or not the contribution of agro-chemical inputs on rice production in the 1970-1989 periods is significant. Estimation is conducted by using time series data comprising four main factors of rice production: rice-planted area, nitrogen-fertilizer, chemical pesticides, and technological progress. Data werecompiled from GOI report. The results of estimation indicate that the increase in rice production during 1970-1989 was not caused by increasing chemical pesticides use, but by the enlargement of planted-rice area, rise in nitrogenous fertilizer use, and technological progress. Key words: fertilicer, pesticides, rice production
