of acid rock, 850 pounds of sulphate of potash, 450 pounds of dried 
blood, 200 pounds of nitrate of soda. This mixture was applied at 
the rates of 500 pounds and 750 pounds an acre. The approxi- 
mate cost of this mixture was $24 a ton, which would make the 
cost of the fertilizer applied equal to $6 in one case and $9 in the 
other. 
(1) Effect of fertelizers on yreld.— When 500 pounds of fertili- 
tilizer per acre were applied, the yield of beets, trimmed and 
washed, increased in 15 out of 17 cases. The increase of yield 
varied from 140 pounds to 9,010 pounds an acre. The average 
increase in all cases amounted to 3,874 pounds an acre. | 
The application of 750 pounds of fertilizer was accompanied by 
an increased yield in every case but one, ay compared with the use 
of no fertilizer. The increase of yield varied from 570 pounds to 
11,790 pounds and averaged 5,264 pounds an acre. 
As compared with the application of 500 pounds of fertilizer 
an acre, the application of 750 pounds was attended by an increase 
except in two cases. The increased yield varied from 240 pounds 
. to 8,170 pounds and averaged 1,390 pounds an acre.

(2) Effect of fertilizers on percentage of sugar.— When 500 
pounds of fertilizer an acre were applied, the sugar content of 
the beets increased in 9 cases and decreased in 8 cases, the general 
average remaining unchanged. With the application of 750° 
pounds an acre, the sugar increased in 4 cases and decreased in 13 
cases, the average decrease being one-half of 1 per cent.
