EXPERIMENTS "WITH MAEQUJS WHEAT. 



25 



RESTJLTS AT MOCCASIN, MONT. 



The varietal experiments at Moccasin have included Marquis 

 wheat during the 3-year period, 1913 to 1915, inclusive. The 

 annual and average yields obtained are given in Table XIX. The 

 average yield of the leading vaxiety in each group is shown in fig-ure 6. 



The hard red winter wheats of the Crimean group outyield all 

 spring wheats at Moccasin by a margin of over 6 bushels per acre. 

 Among the spring wheats the durums do not outrank the spring 

 common wheats, as they have done at most of the other stations; 

 in fact, the best varieties of durum, Fife, and Preston wheats are 

 practically equal in yield. The Marquis leads the Fife varieties by 

 a margin of over 5 per cent. The leading variety of durum wheat 

 and the leading variety of the Preston group of common wheat 

 outyield the Marquis, however, by the narrow margins of 1 and 3 

 per cent, respectively.

CONCLUSIONS. 



The graphic portrayal in figure 6 and the facts given in Tables EK 

 to XIX, inclusive, show that winter wheat is decidedly better than 

 any spring wheat in much of this section. In Central South Dakota 

 and North Dakota, however, winter wheat can not be grown suc- 

 cessfully. 



Among spring wheats, the durums outyielded all the groups of 

 common wheat at all of these stations, except Moccasin, Mont., and 

 Highmore, S. Dak. At all the stations except Highmore, in central 

 South Dakota, the durum wheats outyielded the Marquis variety. 

 At Highmore the high yield of the Marquis wheat was due to the 

 specially favorable location of the Marquis plat in a low spot in 1913. 

 At Moccasin, Mont., however, the yields of the Marquis and the best 

 durum variety were about equal.
