CONCLUSIONS. 



The data in Tables XXI to XXV, inclusive, and in figure 7 show 

 that the Marquis variety has not proved a high yielder at any station 

 west of the Rocky Moimtains. At three stations in Utah, Idaho, and 

 Oregon, winter wheats outyield aU spring wheats. At all five stations, 

 other spring wheats outyield the Marquis, It is not as good, on the 

 average, as the Palouse Bluestem, Early Baart, Fretes, or Ghirka 

 Spring. It also is not as good as several of the new wheats which have 

 been tested at these western stations but are not yet grown commer- 

 cially. Marquis wheat is not recommended for any district west of 

 the Rocky Mountains. 



Results in Irrigated Districts. 



Irrigated farming is confined to the valleys more or less adjacent 

 to the mountains of the Western States. So far as known. Marquis 

 wheat has not been grown commercially under irrigation. 



Experiments to determine the value of 'Marquis wheat under irri- 

 gation conditions have been conducted at four different pohits. 

 Two of these are east and two west of the Rocky Mountains. The 

 stations are Newell, S. Dak.; Huntley, Mont.; Aberdeen, Idaho, and 

 Fallon, Nev. The location of these four stations and the average 

 yields of Marquis wheat and of the best variety in each of several 

 groups of wheat are shown graphically in figure 10. The annual 

 and average yields of the Marquis and several other varieties will be 

 found in Tables XXVI to XXIX inclusive.
