RESULTS AT DICKINSON, N. DAK. 



Marquis ^vlleat has been grown at the Dickinson substation dui'ing 

 three years, 1913 to 1915, inclusive. The annual and average 

 yields obtained from this and other varieties are shown in Table 

 XVIII. The average yield of the leading variety in each group is 

 shown graphically in figure 6. 



The results obtained are nearly the same as those at WilUston. 

 The durum wheats lead by a wide margin. The Marquis is the 

 highest yielding variety of common wheat, and the Kubanka No. 8 

 excels it by nearly 35 per cent. The groups of common wheat rank 

 in the same order as at Williston, namely, Fife, Bluestem, Preston, 

 and Crimean (winter). The Marquis outyields the Rysting, the 

 next best Fife variety, by 1.7 bushels, or 6 per cent, and the Preston 

 by 2.7 bushels, or 11 per cent, while it exceeds the Crossbred Blue- 

 stem by 3.4 bushels, or 14 per cent. The winter wheats are not 

 successfully grown in North Dakota.
