174 AGRICULTURAL EXPERIMENT STATION. [Jan. 



in 1890 (see eighth annual report) ; rye, in 1891 (see ninth 

 annual report). 



The following tabular statement shows the annual applica- 

 tion and special distribution of the manurial 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 plat received the 

 same amount of seed.

1891. — The soil of the field being brought by ploughing 

 and harrowing into a good mechanical condition for planting, 

 the entire area was seeded with winter rye Sept. 5, 1890. 

 Each plat received five and one-half pounds of rye in drills 

 two feet apart. The second largest plate was used in the 

 seeding machine. 



The young plants appeared above ground October 1.
