450 Report of the Department of Field Chops of the 



the use of 2,000 pounds of fertilizer gave a smaller actual yield of 

 beets than did the use of 1,000 pounds and 1,500 pounds of fer- 

 tilizer. It is possible that the use of so large quantities of fertilizer 

 may have affected the seed.

(2) Effect of fertilizers on percentage of sugar. — The general 

 effect of applying fertilizers was to decrease slightly the percent- 

 age of sugar in beets. As between the application of 500 pounds, 

 1,000 pounds and 1,500 pounds of fertilizer, the average percent- 

 age of sugar remained the same. With 2,000 pounds there was an 

 increased percentage of sugar.

(3) Effect of fertilizers on coefficient of 'purity. — The influ- 

 ence of fertilizers upon the coefficient of purity showed a slight 

 decrease up to and including 1,500 pounds of fertilizer. The use 

 of 2,000 pounds was attended with an increase in the coefficient
