CEREAL EXPERIMENTS AT THE AKRON FIELD STATION. 15 
WINTER WHEAT. 
Winter wheat has been more profitable in this section than spring 
wheat. The most important varieties are the hard red winter wheats 
belonging to the Crimean or Turkey group. Six varieties have been 
grown continuously since the Akron Field Station was established 
in 1907. Rate-of-seeding and date-of-seeding experiments were 
started in 1911. Kharkof is the variety that has been used in these 
tests. An excellent field of winter wheat in the vicinity of the 
station is shown in figure 4. 
VARIETAL EXPERIMENTS, 
Experiments with winter wheat have been conducted both on 
field plats and in the nursery. These will be discussed separately. 
PLAT EXPERIMENTS, 
The winter-wheat varieties have been sown each year on land 
prepared by clean'summer fallow. The date of seeding has varied

because of weather conditions. Tabie VIII gives the dates on which 
sowing commenced each year. Except in the fall of 1907, the sowing 
has been done in September. The rate of seeding was 4 pecks 
per acre in 1907 and 3 pecks per acre in the following years. No 
fixed depth of seeding has been used. The object has been to sow 
the seed in moist soil, and in dry seasons this means 2 or 3 inches 
below the surface. Table IX shows the annual and average yields 
of 17 varieties of winter wheat grown at the Akron Field Station 
within the 8-year period, 1908 to 1915, inclusive. 
In the fall of 1907 the winter-wheat varieties were sown on land 
which had been broken the previous summer. Although the seed 
was sown late (Nov. 5), a good stand was obtained, and the varieties 
adapted to this part of the Plains gave fair yields. A number of 
varieties which failed completely are not included in Table IX. 
In the fall of 1908 the seed was treated with formaldehyde solu- 
tion forsmut. The germination wasslow. Counts for stand were not
