TESTS OF G0:RN VARIETIES ON THE GEEAT PLAINS. 
11 
Northwestern Dent seed and the series was repeated five times, 
making, a total area for each variety of about one-nineteenth of an 
acre. The yield in pounds of ears for each row and the total yield 
of each variety are shown in Table III. In 1913 and 1914 the tests 
were made on both irrigated and dry land. The dry-land tests were 
so badly injured by drought in both years that yield records were 
not secured. The irrigated plantings were made in 2-row units 
and the series repeated twice in 1913 and three times in 1914. The 
yield in pounds of ears for each plat and the total yield of each variety 
are also shown in Table III. The check-plat yields are totaled by 
twos or threes, to correspond with the total yields of varieties. 
The yields in bushels per acre and the rank and class of each 
variety for the three years are shown in the summary of Table III. 
The rankings are given according to the average yields of the plats 
of each variety. 
U. S. Selection 133 has produced relatively well in all three years. 
Martens Wliite Dent has outyielded all other varieties by a consider- 
able amount in the two years in which it was grown.
