Yields per Acre. 



Attention is called in commenting upon these results to the 

 fact that manure is used on Plot O at the same rate as on the 

 other plots. 



Asparagus. — Asparagus has long been recognized as a rank 

 feeding crop, requiring liberal application of manure and fer- 

 tilizers. It will be noticed that this is the only one of the three 

 crops which appears to have been materially benefited by the use 

 of the fertilizers. The crop on Plot O, on manure alone, is 

 materially smaller than on either of the other two plots. Par- 

 ticular attention is called to the highly unfavorable effect of the 

 combinations containing the sulfate of ammonia. The yields 

 where this fertilizer was used are much below those produced 

 where the other nitrogen fertilizers are employed, and not ma- 

 terially gi'eater than where no fertilizer is used. 



Strawberries. — It will be noted that in marked contrast with 

 the results obtained with asparagus the yields of strawberries 

 are highest on plots where sulfate of ammonia is used. A sim- 

 ilar result has been obtained in earlier year.s. The highest 

 yield of all has been produced where muriate of potash is used 

 in connection with sulfate of ammonia, a combination which for
