CROPS UNDER FALL IRRIGATION AT SCOTTSBLUFF. 11 
As shown in Table V, the individual yields of oats were in most 
cases higher on the fall-irrigated land, and the same was true with 
respect to the individual yields of straw. In 1911 the proportion of 
straw to grain was uniformly lower on fall-irrigated land than on land 
not fall irrigated, while the reverse was true in 1912 and 1913. Con- 
sidering the average results of each year, the oats on the fall-irrigated 
land were taller in 1911 and 1913 and the same height in 1912; the 
average yield of straw per acre was higher on the fall-irrigated land 
in each of the three years, and the same is true with respect to the 
average yield of grain. Considering the average results of the 3-year 
period, oats on fall-irrigated land grew 1.1 inches taller, produced 135 
pounds per acre more of straw, 11 bushels more of grain, and 4.8 
pounds less of straw per bushel than oats on land not fall irrigated. 
CORN. 
Corn was included in this experiment in 1912 and 1913 only. The 
preparation of the land and the fall irrigation were the same as with 
the crops previously discussed. A local variety known as Calico corn 
was used. The seed was planted in rows 40 inches apart and the 
plants were thinned to 20 inches apart within the row. 
In 1912 the corn was planted in both series on May 8. The crop 
was irrigated once during the season of 1912. No differences were 
noted as to the stage of maturity reached by the corn on the two 
series during the year. The crop was harvested on September 15, at 
which time the grain on all the plats was about 85 per cent matured. 
In 1913 the corn was planted on May 19. During the period from 
July 7 to 12 severe hot winds prevailed and damaged the corn on 
both series to some extent. No differences were noted between the 
plats on the two series as to the damage done by the hot winds. The 
crop was irrigated once during the season. No differences were 
noted as to the stage of maturity reached before frost. The corn 
in both series was harvested on September 18, at which time it was 
practically all matured. 
The numbers of the plats and the yields per acre of stover and of 
grain during the years 1912 and 1913 are given in Table VI. 
Table VI shows that with one exception the individual grain yields 
of corn were higher each year on the fall-irrigated land. Considering 
the averages obtained in each of the two years, the yields of stover 
and of grain were higher on fall-irrigated land than on land not fall 
irrigated, and the proportion of stover to grain was lower on the fall- 
irrigated land. Considering the average results of the two years, 
the corn on fall-irrigated land produced 490 pounds per acre more of 
stover, 10.6 bushels per acre more of grain, and 5.4 pounds less of 
stover per bushel of grain than the corn on land which was not fall 
irrigated.
