Sudan grass was grown each, year by four methods — rows 42 inches 
apart, rows 35 inches apart, double rows 35 inches apart, and drilled 
with a grain drill. Table 23 shows the yields by the different methods. 
It will be noted that the row seedings were as complete failures in 
1919 as the drilled seeding and that in 1921 the advantage over the 
drilled seeding was not sufficient to produce a profitable crop. With 
average yields of about 1 ton per acre for the entire period, the yield 
of the closest spaced rows was only 65 pounds per acre more than 
that of the drilled seeding, and that of the 42-inch rows was less. 
Ripe seed was secured in almost every year that a crop was produced. 
The results of seeding by different methods in larger fields in which 
Sudan grass was grown for feed confirm the results of the plat experi- 
ments.

MILLET 
A limited variety test of millet was conducted from 1917 to 1923, 
inclusive, with the results shown in Table 24. The crop was a total 
failure in two of the seven years, but the yields were heavy in four 
of the other five years. Kursk averaged nearly 1^ tons per acre 
for the 7-year period. This is nearly 470 pounds more than Gold 
Mine, the next highest yielder. Siberian yielded highest in two of 
the three years it was grown.

FIELD PEAS 
The work with field peas consisted of a trial of four varieties from 
1917 to 1923, inclusive, and one other variety in 1922 and 1923. The 
peas were sown in close drills in twentieth-acre plats replicated three 
times. Beginning with 1920 one variety also was grown in double
