Production of Sugar-Beet Seed 



229 



At the Utah Station tests running for nine years gave 

 the following yield of seed from the individual plants : 



TABLE X. AVERAGE WEIGHT OF SEED PRODUCED BY MOTHER 



BEETS 



An acre of land contains about 7000 mother beets. If 

 each one produced as much as the average reported above, 

 nearly 7000 pounds of seed to the acre might be expected. 

 This, however, is not approached in practice. The yield 

 is usually between 1000 and 2000 pounds to the acre. A 

 yield greater than 2000 pounds is exceptional. The 

 average yield of seed for the United States for 1916 and 

 1917 was about 1100 pounds to the acre. 



The fields of commercial seed raised by the Utah Ex- 

 periment Station at Logan have given the following yields 

 during the years 1912 to 1917 inclusive : 



1 There are 453 grams in one pound.
