초록
본 시험은 벼 질소 소비 재배시 생육 및 쌀의 품질에 미치는 영향을 구명하기 위하여 일품벼 등 18종을 공시하여 관행 질소량 11.0 kg/10a와 소비 질소량 5.5 kg/10a로 구분하여 수행한 주요 결과는 다음과 같다. 소비 재배시 관행 재배에 비해 출수기는 1일 빠르거나 같았고, 초장은
This experiment was carried out to identify rice varieties suitable for growing under low N-fertilization levels. Eighteen rice varieties were grown at 5.5 kg and 11 kg/10a nitrogen levels in 2004-2005 in Taegu, Korea. Several varieties like Ilmibyeo, Nampyeongbyeo, Sindongjinbyeo, Dongjin 1 and Donganbyeo yielded more than 470 kg/10a. Low N-fertilization level (5.5 kg/10a) decreased yields of Junambyeo and Donganbyeo by more than 10%. However, the decrease in yield was not significant in Surabyeo and Hwayeongbyeo compared with the 11 kg/10a N-fertilizer treatment. Improved grain quality, chemical properties and palatability was noted in some rice varieties. In terms of rice yield and grain quality, Donganbyeo, Ilmibyeo, Ilpumbyeo, Dongjin 1, Saechoocheongbyeo and Saegyehwabyeo were selected as premising rice varieties for growing under low N-fertilization levels.
