Directions for Tests 



With Different Varieties of Sugar Beet Seed 

 by the Standard Method. 



Comparative tests with sugar beet seed should be carried 

 on by every factory for the purpose of establishing the merits 

 of each variety and in order to ascertain from actual returns, 

 which type is the most remunerative to the farmer and which 

 to the factory. 



It is a well-known fact that the sugar beet is very sensitive 

 to all agencies influencing the growth of plants, such as at- 

 mospheric conditions, character of soil, cultivation and others, 

 and quite frequently a barely noticeable deviation of one or the 

 other produces a material difference in yield or sugar content 

 of a certain variety. Therefore, in order to properly judge the 

 relative value of various sugar beet types, it is essential that 

 they be grown and tested under as nearly uniform conditions 

 as possible. 



Equally as important as uniformity of soil, climatic and 

 other external conditions, are tiie following points, in connec- 

 tion with the standard test method : 



1st : The planting, cultivation and general care of the test 

 field should be handled as nearly alike, as this work is per- 

 formed in the field of the average beet grower. 



2nd: The test field should be as uniform as possible in 

 character of soil and subsoil, also as regards the preceding 

 crop, fertilization and preparation of the ground. Land which 

 has been previously used for experimental work, garden, dump- 

 ing ground for rubbish, etc., is not fit for these test plots. The 

 field selected for the standard test should be most carefully 

 prepared. 



All preparatory work, especially the deep plowing, should 

 be performed under a right angle to the beet rows. The plow- 

 ing should be done by one man with one and the same plow.
