RATE-OF-SEEDING TESTS. 



Rate-of-seeding tests have been conducted on the Arlington Farm 

 by the United States Department of Agriculture with the Stoner 

 (Miracle) wheat for three years, it having been first included in these 

 tests in the sowings made in the fall of 1911. In these tests this wheat 

 was compared in the first year with seven other varieties, four of 

 which are well-known sorts commonly grown among farmers. In 

 the two succeeding years it has been compared with three of these 

 well-known sorts. The names of the varieties used and the yields for 

 the different rates of seeding are given in Table VIII^ only those 

 A'arieties being included which have been used throughout the entire 

 3-year period. In 1912 no seeding of less than 4 pecks per acre 

 was made of any of the varieties. In the succeeding two years seecl- 

 ings of 2, 3, 4, 5, 6, 7, and 8 pecks per acre were made. The plats 

 were one-twentieth of an acre in size in 1912, and the tests were not 

 replicated, but in 1914 the size of the plats was reduced to one- fortieth 

 of an acre, and the sowings were made in duplicate and the results 

 averaged. 



These results show that the best yield of Stoner wheat has been 

 obtained by sowing 4 pecks per acre. When 2 pecks were sown in 

 the two years 1913 and 1914, 22.15 bushels were harvested. In these 

 same years 24.5 bushels were harvested from 3 pecks sown and 

 24.95 from 4 pecks. From sowings of 5, 6, Y, and 8 pecks, less 

 quantities were harvested than from the 3-peck or 4-peck seedings, 

 but in each case more than from the 2-peck seeding. An addition 

 of 2 pecks to the quantity sown has increased the yield over the 

 2-peck sowing an average of 2.8 bushels per acre for the two years. 

 Including the year 1912 and averaging for onl}^ the 4, 5, and 6 peck 

 seedings, the best yield was again obtained by sowing 4 pecks, the 

 yield here, 26.52 bushels, being larger than that secured from sowing 

 either 5 pecks or 6 pecks per acre. Smaller or larger sowings were 

 not made in the year 1912.
