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.
