RESULTS AT BURNS, OREG. 



The Marquis variety has been included in the cooperative varietal 

 experiment at Bums during two years, 1914 and 1915. The annual 

 and average yields of the Marquis and other varieties, representing 

 seven different groups of wheats, are shown in Table XXIII. The 

 average yield of the highest yielding variety in each group is shown 

 graphically in figure 7. 



The results show that aU the varieties in all the groups except the 

 two durum varieties outyielded the Marquis by percentages varying 

 from nearly 5 to over 64. The hard red winter wheats are again the 

 highest yielders, though not so markedly superior as in Utah or even 

 in Idaho. The Palouse Bluestem and Early Baart excel the Marquis 

 here by more than 29 and 27 per cent, respectively. Two varieties 

 of the Preston group, the Fretes and Erivan, outyield Marquis by 

 nearly 10 per cent, while the Little Club excels it by about 5 per cent. 

 In the Fife group, the Ghirka Spring again outyields the Marquis, this 

 tune by 19 per cent.

RESULTS AT MORO, OREG. 



At the Eastern Oregon Dry-Farming 'substation at Moro the 

 cooperative varietal experiments have included the Marquis wheat 

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

 average yields of the Marquis and numerous other varieties are 

 shown in Table XXIV. The average yield of the best variety repre- 

 senting each group is shown graphically in figure 7. 



The tabulated data show that the average yields of aU groups 

 except the durum lie between 21 and 28 bushels per acre. The hard 

 red winter wheat here occupies about the middle of the scale, with a 

 yield of 24 bushels per acre. At Moro the Marquis outyielded the 

 Palouse Bluestem and Little Club about 5 per cent, but is excelled 

 by the Early Baart by nearly 14 per cent. The highest yielding
