CROPS UNDER FALL IRRIGATION AT SCOTTSBLUFF. 
panying the production of each bushel of grain during the three years 
are given in Table III. The plat numbers were the same in each 
series each year. In other words, where plats 5, 11, and 16 in Series 
VI were fall irrigated, the corresponding plats in Series VII grew the 
same crops and were otherwise treated in the same way, except 
that they received no fall irrigation. In studying the table it is 
necessary to keep this in mind and to remember that the figures in 
columns headed U VI" relate to the fall-irrigated plats, while those 
in the column headed "VII" relate to the plats which were not fall 
irrigated.

Table III shows that the average results obtained with wheat during 
each of the three years favored fall irrigation. There were several 
individual instances in which the results did not agree with the average 
results, but the inconsistencies were in all cases relatively small. Con- 
sidering the average results during each of the three years, the wheat 
on fall-irrigated land grew taller and produced heavier yields of straw 
and of gram and a lower proportion of straw to grain than the wheat 
on land which was not fall irrigated. Considering the average results 
of the 3-year period, the wheat on the fall-irrigated land grew 1.7 
inches taller, produced 166 pounds more of straw, 5.5 bushels more of 
grain per acre, and 10.2 pounds less straw per bushel of grain than the 
wheat on the land which was not fall irrigated.
