448 Report of the Department of Field Crops of the 



i. effect of different quantities of commercial plant- 

 foods UPON YIELDS AND QUALITY OF SUGAR BEETS. 



The plats used in the experiments occupied about one-twelfth of 

 an acre at the Station and about one-sixteenth of an acre at Mr. 

 Dawley's farm. All figures given in the tables, and all discus- 

 sions are based upon the results calculated to one acre. 



The following mixture of plant-food materials was employed in 

 these experiments: Two hundred pounds of nitrate of soda, 200 

 pounds of dried blood, 450 pounds of acid rock, and 150 pounds of 

 sulphate of potash. This was applied at the rate of 500 pounds, 

 1,000 pounds, 1,500 pounds, and 2,000 pounds an acre at the 

 Station and in the same quantities, except that of 2,000 pounds, at 

 Fayetteville. In each place two sets of experiments were car- 

 ried on. /
