Table IV shows that the average yields obtained with baleey during 
each of the three years were in favor of fall irrigation, and the same 
was true with all but one of the individual grain yields obtained. 
Barley on fall-irrigated land produced higher average yields of straw 
per acre each year, except 1911. In 1911 and 1912 the barley grew 
somewhat taller on the fall-irrigated land, but in 1913 the height of 
the matured grain was slightly greater on the land which was not fall 
irrigated. The average proportion of straw to grain was lower on the 
fall-irrigated land in 1911 and 1913 and higher in 1912. Considering 
the average results of the 3-year period, the barley on fall-irrigated 
land was 1.8 inches taller than that on land not fall irrigated, and it 
produced 109 pounds more of straw and 7 bushels more of grain per 
acre and 8.4 pounds less of straw per bushel of grain. 
OATS. 
The soil treatment and fall irrigation applied to the plats producing 
oats were the same as those applied to the plats producing wheat and 
barley during the 3-year period. A variety of oats known as ''New 
Market" was used each year, and the seed was planted at the rate of 
10 pecks per acre. 
In 1911 the condition of the soil at planting time, April 20, was the 
same on the oats plats as on the barley plats, and the seed on both
