Low Average Daily Soil Temperature Delays Sugarbeet Seedling Emergence (05/13/21)

Sugarbeet seeds germinate and emerge over a wide temperature range in the presence of adequate moisture and oxygen.

Sugarbeet seeds germinate and emerge over a wide temperature range in the presence of adequate moisture and oxygen. 

In Minnesota and North Dakota, growers have completed planting in most areas. Average daily bare soil temperature has been relatively low (48 F at Cavalier to 51 F at Wahpeton) over the past two weeks during planting. In addition, soil moisture has been low. As a result, germination and emergence have been very slow, especially where there is inadequate moisture. With soil temperature forecasted to increase in the next week, emergence will improve in areas where there is adequate soil moisture. In dry areas, a good rainfall will be required to increase emergence.

The following table gives approximate days to emergence of sugarbeet seeds planted at different soil temperature ranges with adequate moisture. Emergence will be further delayed if moisture is lacking.
