of beets which grew under abnormal conditions, can be fully 

 eliminated. 



Should through some cause or another the entire test field 

 show a very uneven and faulty stand, the selection of the test 

 beets must be left to the judgment of the investigator, and a 

 careful count of the beets in each test plot is necessary so that 

 the records show the prevailing conditions most accurately, fur- 

 nishing at the same time an explanation for the results of the 

 sugar and tonnage tests of these plots. The results from test 

 fields which have a uniformly thin stand, but no bare spots of 

 any consequence, while not of as great value as of a uniformly 

 good stand, can still be used for a fairly accurate calculation 

 of the yield of a variety. In this case the average between the 

 theoretical number of beets p<er acre and the actually counted 

 number of beets per acre, is ascertained, and this figure is then 

 multiplied with the average weight of the test beets. The re- 

 sults obtained from such irregular test fields are not conclusive 

 on the merits of a variety and can only be used for comparison 

 with others grown under the same conditions on the same field. 



llth : The larger the number of beets which are used for 

 the sugar determination, the more accurate are the results ob- 

 tained. The usual equipment and arrangement of a factory 

 laboratory, however, limits the number of beets to be tested, 

 and careful investigation has proven, that it is not necessary to 

 use all the beets from each test plot for analysis. 



The general custom for the selection of beets for laboratory 

 use is the following: After removing all beets grown in open 

 spaces and in outside rows, and others not standing in continu- 

 ous rows, the number of the remaining beets in each plot is as- 

 certained, and accordingly, every fourth, sixth or tenth beet 

 may be selected for the laboratory test. Just what percentage 

 of the normally grown beets should be selected cannot be pre- 

 scribed, as this depends entirely on the stand in the test plots; 

 all that is required is a sufficiently larsre number for the pur- 

 pose of obtaining the most accurate results. Some beets will al- 

 ways have to be discarded after they have been pulled, on ac- 

 count of broken roots, injuries by insects or disease, or for other 

 causes which cannot be detected until the beets have been lifted. 

 It is better to have too many beets than not enough.
