BULLETIN 33, IT. S. DEPARTMENT OF AGRICULTURE. 



the Kherson by the Nebraska Agricultural Experiment Station and 

 the Sixty-Day by the United States Department of Agriculture. The 

 Kherson, as shown in Table XIII, has outyielded the Sixty-Day in 

 all years except one, and for the 7-year period from 1907 to 1913 

 has exceeded it in yield by over 13 per cent. 



THE LATE OROUl'. 



Late varieties of oats are not well adapted to western North 

 Dakota. "When not damaged by hail, drought, or frost, they yield 

 fairly well. Those who wish their oats to mature after the wheat 

 crop is harvested may prefer to grow the later varieties. One variety, 

 the White Russian (C. I. No. 551), has been continued in the trial at 

 Dickinson. The original seed was obtained from the North Dakota 

 Agricultural Experiment Station at Fargo. It is a tall oat, pro- 

 ducing a heavy, rank growth. The panicle is large, long, and one 

 sided. (Fig. 5.) The grain is white, long, but well filled and plump. 

 Unless late oats best fit the system of management on the individual 

 farm, their growth should be discouraged in western North Dakota. 



MISCELLANEOUS DATA ON OATS. 



Some of the more significant data on the varieties of oats included 

 in Table XIII are given in Table XIV. This table shows the com- 

 parative behavior of the different varieties during the growing sea- 

 son, as well as the yield of straw, weight per bushel, height, etc., 

 which are important factors to be considered in making a compari- 

 son between different varieties. 



Table XIV. — Average miscellaneous data for nine varieties of oats grown at the 

 Dickinson substation for periods of three to six years (1907 to 1913). 



[Superior index figures indicate the number of years in which the data were obtained when this number is 

 less than the number of years i:i which the variety was grown.]
