12.84 to"S per acre and of the unfertilized 9.37 tons — a gain of 

 3.47 tons per acre in favor of the fertilized plats. In some 

 instances the gain was very much more marked than in others 

 and was profitably secured. On the average the gain just about 

 paid the cost of the fertilizer and the labor of handling the extra 

 tonnage of beets. In the second and third columns of the fol- 

 lowing table is given the respective yields obtained from the 

 fertilized and unfertilized plats : 



InfIvUEnce of Fertilizer Upon Yield and Quality of Beets. 



(When several varieties were grown fertilized and not fertilized, the average 

 of the fertilized and not fertilized plats is used.)

• bifliience of fertilizer 2ipon quality of beets. — The table given 

 above shows the effect produced by the fertilizer described under 

 the last topic upon the per cent of sugar in the beets and the purity 

 of the juice. Nine experiments gave 20 plats fertilized by the 

 side of 20 plats unfertilized. The average per cent of sugar in 

 the beets produced on the former was 15.28 and on the latter 

 14.74, a difference of .54 in favor of the fertilized plats. The 

 average purity of the juices obtained from the former was 84
