Abstract
The effect of transplanting and sowing date on bolting of
sugar beet (cu. Amazon) was investigated from 1981 to 1983 at
Lincoln College, Canterbury, New Zealand. In addition, the
effect of bolters on the yield and quality was also examined.
Evidence from these experiments indicated a higher bolting
percentage from the mid-August sowing compared to midSeptember or early October sowing. The extent of bolting also
varied with different planting methods; the older the plants
were at the time of planting, the higher was the percentage of
bolters produced. The early bolters reduced the sugar yield by
23.6% compared with the normal plants. Conversely, the late
bolters increased sugar yield by 20.4% compared with the normal plants.
