Abstract

This study was conducted to investigate the response of garlic growth and yield to irrigation water. The garlic seeds using the southern ecotype garlic cultivar, ‘Namdo’. The cloves were planted on the polyethylene film-mulched plots at a planting density of 18 × 11 ㎝ in a greenhouse in September 2002 and harvested in May 2003. The irrigation levels during the experimental period were 30, 20, 10 ㎜ and no-irrigation. In April 30th, plant height and leaf area were 90-96 ㎝ and 415-492 ㎝²/plant under irrigated condition, while 82 ㎝ and 392 ㎝²/plant under water stressed condition, respectively, suggesting that leaf growth was largely inhibited by water deficiency. The distribution rate of large size of garlic bulbs (abov 45 ㎜ diameter) ranges 58.9-76.5% under irrigation, but 39.4% under water-stressed condition. The yield of garlic bulbs was not significant among the 30, 20, and 10 ㎜ irrigation level which was 1,344, 1,239 and 1,157 ㎏/10a, respectively. Overall, this study suggests that the yield of garlic bulbs was significantly decreased under no-irrigation condition.
