Abstract

Shallot is a foreign crop introduced from France in 1995 as a new overwintering field crop with an aim to develop as an export crop. During the introductory cultivation trials, several problems were raised such as premature growth depression in early summer, sensitivity to summer moisture, and weakened vigor of the seed bulbs following successive propagations. This study was conducted to develop proper cultural methods based on annual productivity and adaptability of growing area to address and suggest solutions to some of these problems. Bulb weight was 18.7 g and bulb yield per 10a was 4,113 kg in 1995. In 1996, bulb weight increased to 25.8 g, while bulbs yield per 10a deceased to 2,013 kg. This trend continued in 1997 so that bulb weight increased, and yield per 10a decreased as compared to those in 1996. However, in 1998, both bulb weight (21.1 kg) and yield per 10a (1,246 kg) decreased significantly as compared to those of the previous years. Plant growth from planting to April in the coastal area was better than in other areas. However, the plant growth thereafter until early July was better in the semi-highland area. As a result, the bulb yield in the semi-highland area was 57% more than that in the lowland areas such as the coastal area.

새로운 노지 월동작물과 수출유망 작물을 개발하기 위하여 1995년도에 shallot을 도입하였다. 적응력 시험을 수행하는 과정에서 구 비대기의 고온에 의한 식물체의 조기 고사현상 및 습해 발생으로 수량이 점차 감소되었다. 또한 영양번식체로 세대를 진전시키는데 기인한 종구의 퇴화현상과 같은 문제점이 발생하였다. 이러한 문제점을 해결하기 위하여 연도별 생산성과 지대별 적응성에 따른 shallot의 재배방법을 개발하기 위해 수행하였다. 연도별 생산성은 1995년에는 평균 구중이 18.7 g, 10a당 수량은 4,113 kg이었다. 재배 2차년(1996년)의 평균 구중은 25.8 g으로 무거워졌으나 수량은 10a당 2,013 kg으로 48.9%로 낮아졌다. 재배 3차년의 평균 구중과 10a당 수량은 1996년의 결과와 유사한 경향을 보였다. 재배 4차년(1998년)의 평균 구중은 21.1 g으로 증가하였으나 수량은 10a당 1,246 kg로 도입 당시의 30.3% 수준으로 크게 낮아졌다. Shallot의 고랭지, 준고랭지, 평야지, 해안 지대의 지대별로 적응력을 시험한 결과 식물체 생육은 월동 전 후 및 생육성기인 4월까지는 해안 지대에서 생육이 왕성하였다. 하지만 수확기인 7월에 가까워질수록 준고랭지가 해안 지대에 비해 수량이 57%가 많았다.
