Were further conclusions to be drawn each season should be con- 
sidered separate^, but in each case inspection of the value column 
will show that for each of these three seasons irrigation of grain was 
made to pay. 
IRRIGATION EXPERIMENTS WITH INDIAN AND EGYPTIAN CORN IN 
1910 AND 1911. 
For this work, which extended through 1910 and 1911, the 1-acre 
tract lying directly north of the west end of check 37 was used. 
During 1909 this tract was in sugar beets, and previous to that for a 
number of years it had been in grain. 
In the spring of 1910 it was plowed twice — March 1 and April 9 — 
harrowed, and cross-harrowed. On April 29 the west 2 acres were 
seeded to Yellow Dent Indian corn and the east half to Egyptian 
corn (white durra), a sorghum. In seeding a corn" planter was used 
and the rows were placed 40 inches apart. 
During »the season of 1910 no definite time for irrigation was set 
or definite quantities assigned, both being controlled by the needs and 
conditions of the growing crops. 
INDIAN CORN. 
Immediately after planting the field was divided into four £>lats, 
the water being applied as shown in the following schedule :

Thorough cultivation followed each of these irrigations, and at all 
times the field was kept free from weeds. In the middle of August, 
when the corn was in the milk, it was cut, weighed, and fed green. 
After the crop was removed the land was fall plowed, harrowed, 
and allowed to stand idle through the winter. The following March 
it was again plowed, harrowed, and seeded to ' : Yellow Flint ? ' corn 
and the experiment of 1910 repeated. The area was divided into 
four plats, which received the following amounts of water during 
the growing season,
