EXPERIMENT STATION. 



[Jan. 



Average Yields per Acre on the T/vo Sijsicms of Manuring, Ten Crops. 



It will be noticed that the average yield on plots 2 and 4 

 (lesser manure and potash) has been at the rate of about 3.8 

 bushels j)er acre less than on the larger quantity of manure 

 alone. 



During six years the experimental acre has been in mixed 

 grass and clover. The following tables show the average 

 results per plot and the averages for the two systems of 

 manuring : —

It will be noticed that the average difference against the 

 lesser quantity of manure and potash amounts to a little 

 more than 400 pounds of hay and slightly less than 300 

 pounds of rowen per acre annually. 



The differences indicated by the averages showTi in the 

 above tables, whether for corn or hay, are not sufficient to 

 offset the greater cost of the heavier application of manure.
