36 BULLETIN 1287, U. S. DEPARTMENT OF AGRICULTURE 
Among varieties of hard red spring wheat grown for at least three 
years, Kota ranks first. It has been grown for a period too short to 
justify recommending it for seeding in this section, and it is perhaps 
shehtly later in maturing than is desirable. 
In general, the spring-wheat varieties have headed slightly earlier 
on cornland than on fallow, but have matured at about the same time. 
Most varieties have grown from 3 to 6 inches taller on fallow. Stem- | 
rust infection has been light and has been about the same on the two 
soul treatments. Variation in bushel weight has been slight except 
in Peliss and Pentad, which showed a materially higher bushel weight 
when grown on fallow. Yields of both grain and straw of all varieties 
have averaged higher on fallow. 
RATE-OF-SEEDING EXPERIMENTS 
With the exception of 1917, rate-of-seeding experiments with durum 
wheat have been conducted each year since 1911. From1911t01914, 
inclusive, Arnautka (C. I. No. 4064) was sown. In 1915 the variety 
used was Beloturka (C. I. No. 1520), while in 1916 and in the five 
years from 1918 to 1922, inclusive, Arnautka (C. I. No. 1493) was 
sown. The experiments were conducted largely on single plats on 
summer fallow from 1911 to 1916. In 1918, 1919, and 1920 they were 
grown on duplicate plats on fallow and on cornland and in 1921 and 
1922 on single plats on fallow. The rates of seeding have ranged by 
1-peck intervals from 1 to 7 pecks per acre, but the wheat has not 
been sown at all of the rates during all years of the experiment. 
In 1915 a rate-of-seeding experiment was conducted with the white 
spring wheat, Galgalos (C. I. No. 2398) and in 1916 with the hard 
red spring variety, Marquis (C. I. No. 3641). The rates of seeding 
in these experiments ranged by 1-peck intervals from 2 to 6 pecks. 
An unusually heavy seeding of 16 pecks was made of Marquis in 1916. 
The yields obtained in the rate-of-seeding experiments with durum 
wheat on fallow are shown in Table 18 and the average agronomic 
data in Table 19.

1 Experiment not conducted in 1917. The rate-of-seeding experiments were conducted on both fallow 
and cornland in 1918, 1919, and 1920, but yields from fallow only are reported here. Yields on cornland 
were somewhat less than those on fallow. ‘The varieties used were: From 1911 to 1914, inclusive, Arnautka 
I. No. 4064); 1915, Beloturka (C. I. No. 1520); and in 1916 and 1918 to 1922, inclusive, Arnautka (C. I. 
No. 1493).
