52 BULLETIN 1287, U. S. DEPARTMENT OF AGRICULTURE 
Several selections have been made from Dawn kafir, some of which 
give promise of maturing nearly as early as the Manchu Brown 
kaohang and have the advantage of shorter, stronger, and leafier stalks — 
and white kernels. Figure 22 shows heads of Dawn kafir and Freed 
sorghum selections grown at Akron. 
Because some of the sor gos (saccharine sorghums) produce nearly 
as much seed as kaohang and kafir and at the same time yield more 
forage, no grain sorghums can now be generally recommended to 
farmers of the district. Farther south and east, milo, kafir, and 
feterita are well adapted. 
EXPERIMENTS WITH CORN 
Experiments with corn have been conducted during the past 10 
years. The earlier results have been reported." Detailed data are 
available for only three years, 1920 to 1922, inclusive. The writer, 
working independently, started corn- -improvement studies at Akron 
in 1918. In 1920, 1921, and 1922 the improvement experiments were 
conducted as a cooperative project with the Office of Dry-Land Agri-

Fic. 23.—Average acre yields of five varieties of corn grown at the Akron Field Station in 1921 and 1922 
culture Investigations. The corn varietal experiments, however, have 
been conducted as a project of the Office of Cereal Investigations 
during the past three years. 
VARIETAL EXPERIMENTS 
The yields obtained in the varietal experiments with corn in 1920, 
1921, and 1922 are shown in Table 30. Figure 23 presents gr aphically 
the yields of the varieties of corn grown in 1921 and 19: 32. In all, 
15 strains have been grown in the varietal experiments during one or 
more of the past three years. The corn varietal plats of 1921 were 
located on fallow and those of 1920 and 1922 on soil which had been 
cropped the previous season. The data presented in Table 30 show 
Fulton Yellow and Swadley to be the best yielding varieties grown 
for three years. Akron White has produced excellent yields during 
the two years it has been included in the varietal experiment. Fulton 
Yellow, which is a new variety in this section, appears to be among 
the best of the yellow strains. 
The yields obtained in these experiments have been higher than 
may reasonably be expected under field conditions me this district, 
owing to the favorable corn years of 1920 and 1922 and the fact 
that the corn plats were planted on fallow in 1921. Corn not planted 
on fallow in 1921 at Akron yielded very poorly.
