The organic rice culture (ORC) is watched with keen interest by those who fear deteriorations in foods and ecosystems. To assess the ORC from the view point of crop science, the field experiments were conducted from 1991 to 1993.The yielding ability of the ORC in the experimental plots was significantly lower than that of the control plot. The yields of plots supplemented with chemical fertilizer were equal to that of the control plot. The damage caused by pest and disease in the non-pesticide plots was remarkably slight, but it should be noted that the occurrence of pest and disease varies considerably from year to year. The yield was seriously decreased by weed in the plots to which no herbicide was applied, due to the decrease in the number of panicles. It is suggested that not only input of organic matter to the field but also supplementary applications of chemical fertilizer and pesticide are necessary for high and stable production of ORC.

有机稻米文化（ORC）受到那些担心食物和生态系统恶化的人的密切关注。为了从作物科学的角度对有机肥进行评价，于1991 ~ 1993年进行了田间试验。施化肥小区的产量与对照区相当。在非农药区，病虫害造成的损害非常轻微，但应该指出，病虫害的发生每年都有很大差异。在不施用除草剂的地块中，由于穗数减少，杂草严重降低了产量。因此，有机碳的高产稳产不仅需要有机质的投入，还需要化肥和农药的补充。
