추비시기가 양파의 수량 및 저장성에 미치는 영향 = Effects of top-dressing period on Yield and Storage Quality of Onion(Allium Cepa L.)

국문 초록 (Abstract)

토양분석 결과 시험전에 비해 P_(2)O_(5), K, EC의 함량이 시험 후에 높았고, 식물체 분석결과 늦게까지 추비한 처리에서 C_(a)O의 함량이 높았다. 생육은 처리간 일정한 경향이 없었고 수량은 농가관행의 고형비료 처리가 시험장 및 농가포자에서 ㏊당 53.MT 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 23.6% 및 41.0%인 것에 비해 2월과 3월에 액비로 추비한 것이 15.8% 및 28.9%로 가장 낮았으며, 3월과 4월에 액비로 추비한 것은 20.7% 및 31.7%였다.

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 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.%, 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.
