洋葱（洋葱）产于格鲁吉亚东南部的维达利亚种植区，主要是从农场生产的裸根移植，通常在9月底播种。这些移植是在仲冬（11月至1月）进行的，并重新设置为最后的间隔。研究了洋葱的播期、移栽期、品种效应、产油量和品质。从11月的第一周开始，洋葱可以移植到12月底，产量和质量都很合理。例如，在200304年季节，2003年12月22日移植的洋葱的总产量与11月或12月早些时候移植的洋葱没有什么不同。在2004-05赛季，洋葱移植在2004年12月20日，总产量低于洋葱移植在11月，但没有不同的洋葱移植在2005年1月4日。有些品种形成双鳞茎的倾向可以通过推迟播种和移栽日期来减少。在10月的第一周而不是9月的第四周播种，在12月而不是11月移栽，可以减少某些品种的双鳞茎。
Onions (Allium cepa) produced in southeastern Georgia's Vidalia-growing region are primarily grown from on-farm produced bareroot transplants, which are usually sown at the end of September. These transplants are pulled midwinter (November to January) and reset to their final spacing. This study was to evaluate sowing date, transplanting date, and variety effect oil yield and quality of onions. Beginning in the first week of November, onions can be transplanted until the end of December with reasonable yield and quality. For example, in the 200304 season, total yield of onions transplanted on 22 Dec. 2003 did not differ from any onions transplanted on earlier dates in November or December. In the 2004-05 season, onions transplanted on 20 Dec. 2004, had lower total yield than onions transplanted in November, but were not different from onions transplanted on 4 Jan. 2005. The propensity of some varieties to form double bulbs can be reduced with later sowing and transplanting dates. Sowing the first week of October rather than the fourth week of September and transplanting in December rather than November can reduce double bulbs in some varieties.
