영문 초록

The objective of this study was investigated the effect of organic fertilizer(OF) application on the grain yield, protein content, and soil chemical properties in rice cultivation to evaluate the replacement ratio of OF based on basal fertilization of inorganic(nitrogen) fertilizer, In case of soil 1 with optimum range of organic matter for rice growth, the grain yield of rice in 70% and 100% treatments of OF were higher than the other treatments. In soil 2 with higher than the optimum range of soil organic matter, the grain yield of rice of NPK, 30%, 70%, 100%, and 300% treatments of OF showed no significant difference. When the protein criteria of rice quality was below 7%, the treatment of 30%, 70%, and 100% using OF in soil 1 were satisfied with protein criteria of rice. In case of soil 1, ammonium nitrogen content, electrical conductivity, and the organic matter in 30%, 70%, 100%, 300% treatments of OF showed similar tendency to NPK treatment. These results suggested that the substitution ratio of OF 70~100% could be appropriate to increase the yield and commercial quality for rice.
