春播時期가 마늘의 球形成 및 收量에 미치는 影響 = Effect of Spring Planting Date on Bulb Formation and Yield of Garlic

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the effect of planting date and size of seed cloves on bulb formation and yield in spring plantings of garlic. A split plot design with five replications was used. The main effects were 6 planting dates: at intervals of 10 days from March 5 to April 25, 1979. The subplots were 6 size groups of seed cloves: at intervals of 0.5g from 1.5 to 4.5g.
The results obtained are summarized as follows:
1. Number of cloves per bulb was decreased as planting was delayed. The number of cloves was markedly decreased in the plots planted after April 16. The effect of size of seed cloves on the number of cloves was not significant.
2. Weight of cloves per plant was also decreased as planting was delayed. The weight of cloves per plant was markedly decreased in the plots planted on or after April 16. The weights of cloves both in the outer and inner layers were also decreased as planting was delayed. However, the inner layer cloves were significantly heavier than outer layer ones in the plots planted on or after April 16.
3. When considered the distribution of number and weight of cloves per bulb as influenced by planting date, relatively large cloves weighing 3 to 4g were frequent in the bulbs produced in the plots planted on or before April 4, while relatively small cloves weighing 1 to 2g were common in the plots planted thereafter.
