 complete failure in both years, except when mulched with straw.

RESXJLTS AT EDGELEY, N. DAK. 



The experiments at Edgeley are conducted independently by the 

 North Dakota Agricultural Experiment Station, and the results 

 shown in Table XV have been made available through the courtesy 

 of the director and other officers of that station. The experiments 

 have included the Marquis during three years, 1913 to 1915, inclusive. 

 The results are given in Table XV, and the yield of the leading 

 variety in each group appears in figure 6. 



Winter wheats are not grown at Edgeley. Durum varieties con- 

 siderably outyield either the Fife or Bluestem groups of spring com- 

 mon wheat. The Marquis wheat excels all other varieties in the 

 Fife and Bluestem groups. It outyields the Power, the next best 

 Fife variety, by over 5 per cent and the Haynes by nearly 10 per cent.
