토양분석 결과 시험전에 비해 P , K, EC의 함량이 시험후에 높았고, 식물체 분석결과 늦게까지 추비한 처리에서 CaO의 함량이 높았다. 생육은 처리간 일정한 경향이 없었고 수량은 농가관행의 고형비료 처리가 시험장 및 농가포장에서 ha당 53.2MT 및 56.6MT인 것에 비해 2월과 3월 액비처리는 58.2MT 및 60.8MT, 3월과 4월 액비처리는 53.6MT 및 59.1MT 였다. 8월 하순까지의 부패율은 농가관행 고형비료 처리가 각각
This study was carried out to investigate the yield and storability of onions on top-dressing period. Top-dressing period was applied in February, March and March, April with liquid fertilizer and solid fertilizer of farmhouse practice during the onion growing season. The yields of onion in experimental station field and farmhouse field treated with conventional fertilization were 53.2 and 56.6MT, respectively. However, they were 58.2 and 60.8MT with application of liquid fertilizer in February and March, and 53.6 and 59.1MT with application of liquid fertilizer in March and April. Rotting rates until the end of August were lower with application of liquid fertilizer on February and March(15.8%, 28.9%), compared with application of solid fertilizer by farmhouse practice(23.6%, 41.0%), and were 20.7% and 31.7% by treatment of liquid fertilizer on March and April. In conclusion, treatment of liquid fertilizer on February and March decreased the rotting rate.
