재식거리가 코끼리마늘(Allium ampeloprasum L.)의 생육과 수량에 미치는 영향

Abstract

This study investigated the effect of planting density on growth and yield of elephant garlic. Three planting densities of 20 × 20, 20 × 15, and 20 × 10 ㎝ were tested with the furrow width fixed at 120 ㎝ for the evaluation of elephant galic growth and yield. The average date of emergence was middle and late November, requiring about 30 days for the all emergence. For the flowering, 221 days after sowing were required in all the treatments. Plant height and leaf growth were not significantly different according to the planting density. Flower stalk was shorter when planting density was narrow. The L/D ratio was decreased to form oval shape when planting density was narrow. The yield of elephant garlic was 1,811 ㎏ /10a in planting density 20 × 20 ㎝, 2,375 ㎏/10a in 20 × 15 ㎝, and 2,838 ㎏/10a in 20 × 10 ㎝ plot. The marketable garlic ratio was highest as 1,593 ㎏/10a in planting density of 20 × 15 ㎝.
