alfalfa. The plants were fertilized with 350.84 lbs. of nitrate of soda 

 per acre, and some plats received phosphoric acid at the rate of 53.52 

 lbs. per acre in addition. One-half of the nitrate of soda was applied 

 as a top dressing. The results showed that the application of phos- 

 phoric acid increased the protein content of the beets, and that the 

 red sorts gave greater yields than the yellow. The data for the differ- 

 ent varieties are given in the following table:

Two early and 7 late varieties of oats were tested, and the results 

 are discussed and tabulated. The plats received S9.21 lbs. potassium 

 nitrate per acre, one-fifth being applied as a top-dressing. The results 

 obtained are given in the following table :

In protein content the varieties differed immaterially, but Leutewitzer 

 Yellow contained 5.12 per cent of fat, being nearly 1 per cent more 

 than found in any other variety. 



Among 16 varieties of potatoes, Professor Maercker produced the 

 largest yield of tubers and starch, being 458.1 bu. of tubers and 5,225.9 

 lbs. of starch per acre. Next in order of productiveness was the variety 

 Geheimrat Thiel with a yield of 427.8 bu. of tubers and 4,877 lbs. of 

 starch per acre.
