of the fife varieties next largest, with the bearded fife, and durums 

 following - in the order named. The fife variety White Fife (C. I. 

 Xo. 3319) gave the greatest average volume (2,370 c. c.) to the loaf. 

 The volume of the loaf, as well as the texture and other important 

 factors, are shown in cross sections of these loaves of bread in Plate I. 

 The average volume of loaf of four varieties of fife wheat in 1911 

 was 2 per cent greater than that of four varieties of bearded fife 

 wheat. In 1913 five varieties of fife wheat gave a loaf volume 7 per 

 cent greater than five varieties of bearded fife wheat. An average 

 for the two years gives a gain of 4.5 per cent in favor of fife wheat. 

 The average yield of straight flour for the two classes of wheat was 

 practically the same. 



Wintek Wheat. 



Varietal tests with winter wheat were started in the fall of 1912. 

 The results of only one year are therefore available. The trial in- 

 cluded five varieties. Plantings were made in duplicate, one set being 

 planted on fallowed land, the other on corn land with the cornstalks 

 left standing. An average yield of 13.5 bushels per acre was obtained 

 from the varieties planted on corn land and 4.7 bushels per acre from 

 the same varieties planted on fallowed land. The standing corn- 

 stalks caught the drifting snow during the winter, which resulted in 

 giving a measure of protection to the wheat plants. Stand notes of 

 plants per acre taken in the fall shortly after emergence, and again 

 in the spring after the surviving plants had made some growth, 

 showed an average survival for all varieties on the corn land to be 33 

 per cent and on fallowed land 19 per cent. 



The varieties yielded according to their percentage of survival. 

 The variety having the greatest survival was North Dakota No. 1997 

 (C. I. No. 3084), a bearded variety of the Turkey type. The next 

 most hard} 7 variety was Beloglina (C. I. No. 1543), with Kharkof 

 (C. I. No. 1583) and Turkey (C. I. No. 1571) following in the order 

 named. Turkey wheat, which has been under trial for several years 

 at Dickinson, has given indifferent results, the stand in all seasons 

 being greatly reduced by winterkilling. Many different cultural 

 methods have been used in an attempt to find a method of producing 

 a profitable crop of winter wheat. In all cases either total or severe 

 winterkilling has resulted. 



It is evident that North Dakota will continue to grow spring 

 rather than winter wheat until different cultural methods from any 

 now advocated are used or until hardier varieties or strains of winter 

 wheat than any yet known are produced. 



OATS. 



The actual acre yields obtained from trials with 38 varieties of 

 oats grown at Dickinson from 1907 to 1913 are presented in Table
