Buckwheat. 



271 



strips in this field were plowed, one near the east end and afterward con- 

 stituting plats 21 and 2.2 of the experiment, another near the middle and 

 becoming plats 9 and 10. 

 The purpose of plowing 

 these strips was to de- 

 termine whether better re- 

 sults would be secured by 

 turning the rye under in the 

 early season or by allowing 

 it to grow till shortly before 

 drilling in the buckwheat. 

 On June 20th, the entire 

 area, including the two 

 strips just mentioned, was 

 plowed. At this time the 

 rye in some places was as 

 high as the horses' backs 

 and a heavy chain was used 

 to draw it under the fur- 

 rows. In preparing the 

 seed-bed the harrow and 

 roller were each used twice. 

 The seeding was at the rate 

 of three pecks per acre and 

 the drilling was done on 

 June 24th. The varieties 

 sown, the fertilizers ap- 

 plied to the various plats 

 and the computed yields per acre are best shown in the following table. 

 Each plat was approximately one-tenth acre. Plats i to 8 sown with the 

 Japanese variety constitute one fertilizer test and plats 12 to 23, excluding 

 13, 21 and 22, sown with Silver Hull variety, constitute a duplicate test :
