Table I — Yields per Plot. 



[Bulletin 208 



The value of extra nitrogen, jjarticularly manure, is shown very graphi- 

 cally by the above table, although plot 3, which did not receive any manure, 

 is showing up better than it did with sweet corn and dry beans. The fer- 

 tilizer treatments were costly in relation to the value of the crop as will 

 be shown by the following table. The manure was valued at $2.50 per 

 ton and the other fertilizers at the 1922 spring prices as follows: 



Nitrate of Soda $53.00 per ton 



Tankage 33.00 " " 



Acid Phosphate 16.50 " " 



Potash 48.00 " " 



Table II — Value op Crop Less Cost of Fertilizer. 



The north half of the plots are limed on the even years at the rate of 2000 

 pounds of hydrated lime per acre. These applications of lime have been 

 made in the spring of 1918, 1920, 1922.
