TESTS OF CORN VAKIETIES ON THE GREAT PLAINS. 
15 
varieties are not sufficiently large to indicate the superiority of any 
one of them. White Austrahan has occupied a very high rank in 
the years in which it has been grown. It should be given further 
trial as a corn for hogging off. 
TESTS AT NORTH PLATTE. 
The results of only one year are available from the station at North 
Platte, Nebr. The tests were made on dry land. Plantings were 
made in 1912, 1913, and 1914. In 1913 and 1914 the drought injury 
was so severe that yield records were not made. The variety units 
were made up of plats 175 feet long and 7 feet wide, making an area 
of about one thirty-fifth of an acre, and each plat contained two rows. 
The variety plats were alternated with check plats, all planted to the 
same variety. The series was grown in duphcate. 
The yields in pounds of ears of each plat and the total pounds of 
ears produced by the two plats of each variety are shown in Table V. 
In the total column, the yields of the check plats are combined by 
twos in the same order as the plats of the different varieties. 
Actual and corrected yields per acre and the rank and class of 
each variety are shown in the summary. The corrected yields are 
secured by decreasing or increasing the actual average yield of the 
two plats of each variety by the amount the average yield of the four 
adjacent check plats exceeds or faUs below the average yield of all 
check plats. The rankings are according to corrected yields.
