The seedling production potential of 100 seedballs of table beets may vary from one seed lot to another from fewer than 100 seedlings to more than 200. Thus, in order to obtain desired stands of plants, it is necessary to adjust planting rates in accordance with seedling production potential. ...This circular was prepared partly to provide a sufficiently detailed description of the sand test to guide others in using it, partly to present research data concerning the accuracy of the sand test in predicting field stands of table beets, and finally to illustrate the manner in which sand test results can be used to adjust planting rates to obtain desired stands of table beets under favorable field conditions.
