RESULTS AT LANGDON, N. DAK. 



At Langdon, as at Edgeley, the experiments are conducted inde- 

 pendently by the North Dakota Agricultural Experiment Station, 

 and the results are used here by courtesy of the director and his 

 associates. The experiments have included the Marquis during only 

 two years, 1914 and 1915. The annual and average results are shown 

 in Table XVI and the yield of the leading variety of each group in 

 figure 6. 



The results may be seen at a glance. The two durum varieties far 

 excel the Marquis and Glyndon. In the Fife group the Marquis out- 

 yields the Glyndon by 6 bushels, or more than 27 per cent. The 

 yields of Bluestem varieties under the same conditions are not 

 reported.

RESULTS AT WILLISTON, N. DAK. 



The varietal experiments at Williston have included Marquis 

 wheat during three years, 1913 to 1915, inclusive. The annual and 

 average yields are shown in Table XVII, and the average yield of the 

 leading variety in each group is shown graphically in figure 6. 



At WiUiston, as elsewhere, the durum varieties excel any spring 

 common wheats in yield. The best durum., exceeds that of the 

 Power, the best spring common, by 4.6 bushels, or nearly 14 per cent. 

 Considering only the common wheats, the rank of the groups is Fife, 

 Bluestem, Preston, and Crimean (winter), in the order named. 

 Among the Fife varieties, the Power outyields the Marquis by 1 

 bushel, or 2.5 per cent. The Glyndon, in the Fife group, and the 

 Dakota, a Bluestem variety, almost exactly equal the Marquis in 

 yield. The yields of the winter-wheat varieties are very low. 



The comparatively low yield of the Marquis in 1915 was due to 

 damage by a late spring frost. The plants were about 8 inches tall 

 at the time. Not only at WiUiston but also at other points in the 

 State the Marquis seemed to be more seriously injured than other 

 varieties.
