초록

In an experiment of organic manure to substitute for chemical fertilizers in rice-cropping, the amount of applied fertilizer tended to increase pH and organic matters, depending on chemical characteristics of soil with organic fertilizers.
At first, that tendency about growth characteristics was shown in treatment group, which was applied organic manure and chemical fertilizers, comparing with control group. However,after growing period, leaf area, fresh weight, and dry weight in seventh treatment group applied 12 kg / 10 a of organic manure was higher than in other groups. There was no significant difference of the number of glumous flowers or percent ripened grain in terms of yield component, and control group and treatment group yielded above 500 kg per 10a. Especially, the highest figure was from seventh treatment group, 538 kg / 10 a.
Furthermore, quality of rice grain showed not much difference,depending on whether or not applying organic fertilizers.
As a result of the experiment, applying organic manure improves the physical property of soil. It is clear that organic fertilizers can be substituted for chemical ones since there is no difference from yield component and quality of brown rice, comparing with chemical fertilizers which have been used conventionally. The proper amount of organic manure is 267 kg per 10a; it makes good quality of yield.
