396 Bulletin 182. 



From ail inspection of table No. 1 it may be seen that in the indi- 

 vidual experiments important differences as to yield, content of sugar 

 and purity of juice occur. These differences are sometimes sufficient 

 to materially affect the profitableness of the crop, but the different 

 varieties do not fall into any regular order as to yield or quality of 

 crop. Each variety takes first place in some experiments and last 

 in others. 



Kleinwanzlebener produces largest yield in three cases and smallest in foiir. 



Vilmorin " " " four " " eight. 



Zehringen " " " two " " seven. 



Mangold " " " six " " one. 



Biendorf Elite Klein. " " " four " " five.* 



A Study of the kinds of soils upon which these experiments were 

 conducted does not seem to indicate that any one of these varieties 

 is preeminently adapted to a particular soil. 



As regards the quality of the beets it is also true that each variety 

 takes first place in some experiments and last in others, but here 

 there is a marked tendency for Kleinwanzlebener and Zehringen to 

 appear at the head of the list, Vilmorin and Biendorf Elite Klein- 

 wanzlebener to appear at the foot. 



Kleinwanzlebener shows largest % of sugar in ten cases, smallest in four. 



Vilmorin " " " " one " " seven. 



Zehringen " " " " ten " " one. 



Mangold " " " " three " " three. 



Biendorf Elite Klein " " " " one " " nine. 



In some instances the highest content of sugar is associated with 

 the largest yield, but the tendency is to reverse this and associate 

 high quality with low yield and vice versa. 



In table No. 2 are given the averages of the several varieties as 

 set forth in table No. 1. The yields per acre are the averages for 

 nineteen plats each growing the five varieties mentioned, except that 

 Biendorf Elite Kleinwanzlebener was omitted from one plat. The 

 columns showing the percentage of sugar and the purity of the juice 

 are the averages for twenty-four plats each growing the five varieties 

 except that the variety mentioned above was omitted from two of 

 them.
