Verification test for harvest supplement by post-sowing of garlic in South Korea

After planting the garlic in winter season, the farmer spent additional time and labor to find out miss-planted pot and non-germinated pot for supplement the total yield of garlic in South Korea. With the intuition aspect, post-planted garlic clove has a difficulty of growing and the differences between early and late planted garlic can be reflected by the quality of garlic in harvest season. In this study, the physical characteristics of conventionally planted and post-planted garlic compared and the effect of post-planted operation was discussed. The garlic cloves were planted on late November of 2023 in conventional method and irrigation and management also conducted with it. After taking terms of germination, missed and non-germinated pots were investigated and additional garlic cloves were prepared for post-planted experiment. The hundred of garlic cloves were post-planted in randomly on 1^st December 2023 and management of whole field was performed in general. As an interim finding, planted garlics were taken on 19^th April 2023, a diameter of main stem, vertical length of garlic, number of leave, width and length of first two leave were selected as physical characteristics for the comparison. The degraded physical characteristics of post-planted garlic were found except in number of leave, a diameter of main stem and vertical length were 72.6% and 76.58% less than that of conventionally planted garlic. The width and length of leaf was 50% less growth than the conventionally planted garlic. However, garlic with an awareness shape was not recognized and similar level of the number of leave was found which indicated that they were in same phenological growth stage.
