SUGAR BEETS. 
The soil treatment for sugar beets was the same as that previously 
described in connection with the other crops in this experiment. 
Sugar beets were planted in 1911, 1912, and 1913. 
In 1911 the beets were planted on April 30. At this time the soil 
on Series VII, which was not fall irrigated, was so dry that none of 
the seeds germinated until about May 20. At this time heavy winds 
caused considerable soil drifting, which so damaged the crop on 
Series VII that the stand was reduced to such a point as to be con- 
sidered a failure. It was too late to reseed, and sugar beets were 
therefore discarded for the year 1911. 
In 1912 the beets were planted on April 27 in rows 20 inches apart, 
the seed being planted at the rate of 15 pounds per acre. Soil drift- 
ing again destroyed the stands, and the plats were reseeded during 
the second week in May. A good stand was secured from the second 
seeding. The beets were irrigated three times during the season. 
In 1913 the beets were planted on May 20 in rows 20 inches apart, 
the seed being planted at the rate of 17 pounds per acre. The plants 
were thinned to 12 inches apart in the row. The crop was irrigated 
three times during the season. The numbers of the plats and the 
yields per acre obtained during 1912 and 1913 are stated iu Table VII. 
Table VII shows that the average yield of sugar beets was higher 
each year on the fall-irrigated land than on the land which received 
no fall irrigation. The average results of the two years show an 
increase of 1.6 tons per acre in favor of fall irrigation.
