172 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The following tabular statement shows the annual applica- 

 tion and special distri])ution of the nianurial substances with 

 reference to each plat since 1889. The fertilizers were in 

 every case applied broadcast as early as circumstances per- 

 mitted. They were slightly harrowed under before the seed 

 was planted in rows by a seed drill. Each })lat received the 

 same amount of seed.

1892.— The field was ploughed April 19 and 20. The 

 barn-yard manure was applied to Plat April 15 ; the re- 

 maining plats, 1-10, received May G their different mixtures 

 of commercial fertilizers, broadcast, after which the entire 

 field was harrowed and rolled. The seed was sown in drills 

 two and one-half feet apart May IG, at the rate of seven 

 pounds to each })lat. 



The soja bean seed, a late maturing variety, was bought of 

 J. M. Th()r])urn & Co., New York City, at eight cents per 

 pound. The crop was cut for ensilage September 8. 



The young plants appeared above ground May 28 ; they 

 were cultivated and hoed June 3 and July 17, when they
