TESTS OF CORN VARIETIES ON THE GREAT 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 White Dent has outyielded all other varieties by a consider- 

 able amount in the two years in which it was grown.
