SUGAR BEETS: PREVENTABLE LOSSES IN CULTURE. 21 



The data here presented show a strong correlation between per- 

 centage of stand and yield. The existence of a relation between yield 

 and percentage of stand has been demonstrated frequently under 

 experimental conditions in Europe and rather less frequently in the 

 United States. Therefore, it is believed that the losses in stand 

 shown to take place progressively throughout the season correspond 

 to a loss in yield. However, it is also shown, through apparent 

 exceptions to this correlation, that despite a stand of fair percentage 

 at the outset the yield may remain comparatively small through' 

 neglect and carelessness during the season. 



There is found to be a moderate uniformity in methods, but great 

 irregularity and discrepancy are conspicuous in the thoroughness 

 of their application; in other words, efficiency varies greatly. 



It is not to be expected that every beet grower, although he may 

 possess fields well adapted to beet culture, can at once obtain such 

 yields as the best of those mentioned in this paper. However, such 

 yields should be possible on many farms when, after a few years 

 of thorough cultivation, the fields have been worked up into equally 

 good condition. The benefits accruing from increased yields of beets 

 through improved tilth of the soil are especially pronounced. 



These studies were made among fair and good beet growers in an 

 old beet district whose mean yield reached the respectable total of 

 rather more than 17 tons to the acre, while the average for the United 

 States for 1910-11 was only 10.17 tons and that for the State of 

 Utah, where these studies were made, was 11.42 tons per acre. The 

 magnitude of preventable loss incurred by a very large proportion of 

 beet growers must be amazing; in fact, it must exceed the entire cost 

 of raising the crop.
