초록

For the environmental protection, it is more desirable to use compost rather than chemical fertilizer. So in this paper, the effects of compost upon the rice quality were investigated with Hwajin Rice as the test variety. The rice quality and physicochemical characteristics were examined and the resrlts are as follows. As to the rice quality, the rate of polished rice was high in the non-fertilizer and the compost plot, the degree of transparency was high in the order of the traditional, the compost+urea, the compost and the non-fertilizer plot. The amylose content (one of the physicochemical characteristies of the rice), the rate of Mg/K, and the adhesivity and the cohesion power (charateristies of texturogram which show the density of boiled rice) were also high in the compost polt. Among the amylogram characteristics, the gelatinization temperature was lowest in the compost plot ; the lowest and the highest degree of viscosity and the break down were also inclined to be higher in the compost plot than in the traditional plot. After the soil test, the components of available phosphorus, organic matters, calcium, magnesium, potassinm and silicate increased in the soil as compared with those before test.
