Abstract

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.

논 조건의 포트규모에서 유기질 비료로 화학비료 밑거름량을 대체하기 위해 벼의 정조수량, 쌀 품질 기준인 단백질 함량, 토양 화학적 특성에 미치는 영향을 조사하였다. 벼 생산에 적정인 유기물함량을 지닌 토양 1에서 벼의 생산량은 다른 처리구보다 70 %, 100 %에서 높았다. 벼 생산에 적정보다 높은 유기물함량을 지닌 토양 2에서 벼의 생산량은 NPK, 유기질비료 30%, 70%, 100%, 300%에서 차이가 없었다. 쌀 품질에 대한 단백질 기준이 7 % 이하를 적용할 때 유기질비료 3종(혼합유기질비료, 혼합유박, 유기복합)의 처리구 중에서 70 %, 100 % 처리구가 쌀 품질의 단백질 기준에 적합하였다. 유기질비료 30 %, 70 %, 100 %, 300 % 처리에서 유기물 함량, 암모늄태 질소 및 전기전도도는 NPK 처리와 유사한 경향을 보였다. 이러한 결과로부터 표준 질소 밑거름 시용량의 70 ~ 100 % 수준으로 유기질 비료 3종에 대해 투입하는 것이 농경지의 적절한 양분을 유지하고 쌀의 수확량과 품질을 유지하는 좋은 방법이라 판단된다.
