This study was conducted to investigate for bulb yield and seed clove production using large bulbils of the garlic 'Namdo' cultivar in Southern regions from September 2005 to June 2007. Planting dates were planted on 5,15 and 25 September and bulbil weights were 0.8, 1.0, over 1.1 g, and over 1.5 g. Those were planted on the polyethylene film-mulched plots at a planting density of 18×11cm. In the planting dates trials, plant height, leaf sheath length and leaf sheath diameter of garlic in field were a few different and the rate of secondary growth of cloves in 2007 was 3.3~4.7% among the planting dates. The percentage of large bulb diameter(over Ø 4.5cm) was 61.4, 57.6, and 45.5%, respectively. Bulb weight and yield of garlic increased at early planting dates as 34.2, 33.0, 32.3 g and, 1,246, 1,213, and 1,156 kg/10a, respectively. But those were not significant among the planting dates. In the trial bulbil weights with 0.8, 1.0, over 1.1 g and over 1.5 g, the larger bulbils, the better growth of garlic plants. The distribution rate of large bulb diameter different bulbil weights were 42.3, 46.3, 54.4% and 62.9%, respectively. Bulb weight and yield of garlic increased to larger bulbils as 28.3, 30.2, 32.8 and 34.1 g and 1,046, 1,116, 1,214, and 1,269 kg/10a, respectively. But the garlic yield of clove was 1,440 kg/10a. Number of seed cloves of over 3 g were 206, 216, 239, and 245 cloves/㎡, respectively. Thus, it is possible that the marketable garlic and seed clove production with large bulbils over 1.1 g cultivation.
