CEKEAL EXPERIMENTS AT DICKINSON, N. DAK.

Table XIV shows that the earty varieties, the Kherson and Sixty- 

 Day, matured in about 103 days after planting. The medium-early 

 varieties, such as the Early Mountain and Victory, mature in about 

 117 days, the medium-late variety, Banner, in 123 days, and the late 

 variety, White Russian, in 128 days. The average date of heading 

 for the medium-early varieties is July 11 and the average date of 

 ripening August 13. The early varieties mature about two weeks 

 earlier and the medium-late and late varieties 6 and 11 days later, 

 respectively. The time of maturing is an important feature to be 

 considered with the oat crop. Early varieties often escape climatic 

 conditions, such as hail and hot winds, that seriously injure later 

 varieties. 



The average height of the early varieties is about 28 inches, which 

 gives sufficient length of straw for binding. The average height of 

 the other varieties is about 36 inches. Stand notes which have been 

 taken for a number of years show no definite correlation with yield 

 between the different varieties. The early varieties yield less straw 

 than the later ones; hence, the latter are to be preferred when the 

 straw is to be used for feed. The earlier varieties also usually weigh 

 less to the measured bushel. The medium-early varieties, however., 

 yield well in straw and the weight per bushel is high. 



BARLEY. 



The varietal trials of barley have been conducted in much the same 

 manner as those of wheat and oats. In 1907 and 1908 the barley 

 varieties were grown on new land which had been broken the previous 

 year. In 1909 and in succeeding years they were grown on corn land- 

 disked just previous to seeding. The usual date of seeding has been 

 about April 20, though in 1912 the seed was not sown till May 8.. 

 The rate of seeding has varied from 8 pecks to the acre in 1907 and 

 1908 to 5 pecks in 1912 and 1913. In 1912 the second growth, which 

 was produced after the hailstorm of July 11, matured seed, but only 

 four varieties were thrashed because of lack of help. 



The actual acre yields obtained from 16 varieties grown at Dickin- 

 son from 1907 to 1913 are presented in Table XV.

1 For comparison, the yields of the naked varieties are given in bushels of 48 pounds. The actual yield 

 in bushels of 60 pounds, the standard weight, would be one-fifth less.
