Abstract

This study was conducted to evaluate the effect of mulching material and planting density on growth and bulb development of shallot. The transparent PE film was better than black PE film as a mulching material for the overwintering shallot crop. Transparent PE film mulching promoted plant growth and increased marketable yield by 21% as compared with that of the black PE film-mulched crop. However, the bulb size was not significantly affected by the type of mulching film. The height and width of ridge and planting density significantly affected the growth and bulb yield of the moisture sensitive shallot. Bulb yield of the shallot planted in five rows in 120 cm wide ridges (20,833 plants per 10 a) was 1,332 kg per 10 a, which was 1.7 times as high as that by the crop grown in three rows in 120 cm wide ridges (12,500 plants per 10 a). In conclusion, the shallot crop is recommended to be cultivated in five rows in 120 cm ridges mulched with the transparent PE film.

본 연구는 멀칭재료와 재식방법에 따른 shallot의 생육에 미치는 영향을 조사하였다. 멀칭비닐 종류별 시험에서 투명 PE필름 처리구에서 흑색 PE필름보다 엽수, 초장, 엽초장, 엽초경이 더 좋았고, 상품수량도 21%나 증수되었다. 그러나 구의 크기별 분포에서는 유의적인 차이가 없었다. Shallot의 재식밀도별 수량은 120 cm 5조(10 a당 20,833주)에서 1,332 kg으로 120 cm 2조(10 a당 12,500주)에서보다 1.7배가 증수되어 밀식재배가 유리하였다. 따라서 shallot의 재배는 투명 PE필름 멀칭에 휴폭 120 cm에 5조가 좋을 것으로 사료된다.
